How many ships are in the sea battle game. How to play sea battle on a leaf

06.12.2020

A couple of days ago, I was surprised to learn that some of my acquaintances do not know how to play sea battle. Those. They know the rules, of course, but they play somehow haphazardly and in the end they often lose. In this post I will try to outline the main ideas that will help you to improve the level of your game.

Rules of the game

There are many options for naval combat, but we will consider the most common option with the following set of ships:

All of the listed ships must be placed on a 10 by 10 square field, and the ships cannot touch either by their corners or sides. The playing field itself is numbered from top to bottom, and the verticals are marked with Russian letters from "A" to "K" (while the letters "E" and "Y" are omitted).

An enemy field of the same size is drawn next to it. With a successful shot at the enemy's ship, a cross is placed on the corresponding cell of the enemy field and a second shot is fired, with an unsuccessful shot, a dot is placed in the corresponding cell, and the move goes to the enemy.

Optimal strategy

There is always an element of randomness in the sea battle game, but it can be minimized. Before proceeding directly to the search for the optimal strategy, it is necessary to voice one obvious thing: the probability of hitting an enemy ship is the higher, the fewer unchecked cells are left on his field, similarly, the probability of hitting your ships is the lower, the more unchecked cells are left on your field. So To play effectively, you need to learn two things at once: optimal shooting at the enemy and optimal placement of your ships.

In the following explanation, the following conventions will be used:

Optimal shooting

The first and most obvious rule of optimal shooting is the following rule: do not shoot at the cells immediately surrounding the destroyed enemy ship.

In accordance with the designations adopted above, in the figure those cells at which unsuccessful shots have already been fired are marked in yellow, the cells at which the shots ended with a hit are marked in red, and the cells that were not fired at are marked in green, but it can be guaranteed that the ships they are not (there cannot be ships there, because according to the rules of the game the ships cannot touch).

The second rule immediately follows from the first rule: if you managed to knock out an enemy ship, you must immediately finish it off in order to get a list of guaranteed free cells as soon as possible.

The third rule follows from the first two: it is necessary first of all to try to knock out the largest enemy ships. Perhaps this rule is not obvious to you, but if you think a little, you can easily notice that by destroying an enemy battleship, at best, we will receive information immediately about 14 guaranteed free cells, and by destroying a cruiser, only about 12.

So the optimal firing strategy can be reduced to a targeted search and destruction of the largest enemy ships. Unfortunately, it is not enough to formulate a strategy; it is necessary to propose a way to implement it.

First, let's look at a section of the playing field measuring 4 by 4 cells. If there is an enemy battleship in the area under consideration, then it is guaranteed that it can be knocked out in no more than 4 shots. To do this, you need to shoot so that on each horizontal and vertical there is exactly one checked cell. below are all variants of such shooting (excluding reflections and turns).

Among all these options, only the first two options are optimal on a 10 by 10 squares field, guaranteeing hitting the battleship in a maximum of 24 shots.

After the enemy battleship is destroyed, you need to start looking for cruisers, and then destroyers. In this case, as you may have guessed, you can use a similar technique. Only now it is necessary to divide the field into squares with sides of 3 and 2 cells, respectively.

If you used the second strategy when searching for a battleship, then to search for cruisers and destroyers you need to shoot at the following fields (green fields are marked at which you have already fired when searching for a battleship):

There is no optimal strategy for finding boats, so at the end of the game you have to rely mainly on luck.

Optimal ship placement

The optimal ship placement strategy is in a sense the opposite of the optimal firing strategy. When shooting, we tried to find the largest ships in order to reduce the number of cells that need to be checked, at the expense of guaranteed free cells. This means that when placing the ships, they must be placed in such a way that in case of their loss, the number of guaranteed free cells is minimized. As you remember, the battleship in the center of the field opens 14 fields for the enemy at once, but the battleship standing in the corner opens only 6 fields for the enemy:

Likewise, a cruiser in a corner opens only 6 fields instead of 12 fields. Thus, by placing large ships along the border of the field, you leave more room for boats. Because There is no strategy for finding boats, the enemy will have to shoot at random, and the more free fields you have by the time you catch boats, the harder it will be for the enemy to win.

Below are three ways to place large ships, which leave plenty of room for boats (blue):

Each of the given arrangements leaves exactly 60 free spaces for the boats, which means that the probability of accidentally hitting the boat is 0.066. For comparison, it is worth giving a random arrangement of ships:

With this arrangement, there are only 21 cells left for the boats, which means that the probability of hitting the boat is already 0.19, i.e. almost 3 times higher.

In conclusion, I want to say that you should not spend too much time playing naval combat. I especially want to warn you against playing in lectures. When I was sitting in Wabi-Sabi and playing naval combat with my girlfriend, a waitress walked by and said that she was playing very well, because practiced a lot in pairs. Who knows who she would have worked if she had attended lectures at one time?

P.S. In the comments, it is absolutely true that there have already been similar publications on Habré, it would be wrong not to link to them.

Children are so keen on various gadgets that they often do not want not only to read, but even to play in virtual reality. This worries both professionals and parents. In one of the episodes of the cartoon "Barboskins", Grandpa just offers a way to return children to the real world by playing with the whole family in an ordinary "Sea Battle" on paper.

To do this, he turns off the electricity in the house, and the grandchildren are forced to master the game, which does not require any special conditions. He showed that you can spend time interestingly without any Internet, armed only with a pen and your own mind.

Although this board game Sea Battle now exists in the computer version, the traditional version of destroying ships on a piece of paper in a box has one undoubted advantage over the virtual one.

It is more interesting to play with a real person than with a computer, the fight turns out to be much more fun and exciting. And it is even more useful, because in this case the child develops not only logic and strategic thinking, but also intuition, the ability to “calculate” and read the emotions of another person.

Another plus and reason for the long-term popularity of the game is the simplicity of its organization. In order to lead ships into battle, you do not need the Internet, electricity, a large room or any special surroundings. Enough paper, pen and know sea battle on paper for two.

Learning to play sea battle

The rules for naval combat for two people are pretty simple. On paper, each player must draw a square of 10x10 cells, which are designated on one side by letters from A to K (without E and Y), on the other by numbers from 1 to 10. In this field you need to place your ships.

A second square is drawn next to it with the same designation for the fields. On it, during the battle, the player fixes his shots.

Making a "shot" the player names the target coordinates, for example, B8.
The opponent answers "by" if there is nothing in the cell; "Wounded" if his ship was hit; “Killed” when the ship is destroyed.
Hitting a foreign ship is indicated by a cross. In this case, the rules give the right to the next shot.
On a miss, the right to shoot passes to the second player. The winner is the one who is the first to destroy all enemy ships.
At the end of the game, the participant can demand that the opponent show his playing field and check the records of moves.

The rules of the Sea Battle game stipulate not only how many and what size ships are involved in the battle, but also their location.

The composition of the ships: 4 submarines of one cell, 3 destroyers consisting of two cells, 2 cruisers of three cells and one four-cell battleship.
Draw the ships so that they do not touch each other in any way. There must be at least one cell distance between them.
Ships can be placed horizontally, vertically, and at the edge of the playing field.

What not to do

They stipulate rules and certain restrictions.

You cannot change the composition of ships.
Some rules say that one ship can only have a linear shape, in some versions the shape of the letter G is allowed. This point must be discussed in advance. But in all variants, you cannot draw and arrange ships diagonally.
The value of the field cannot be changed.
You cannot distort coordinates and hide the hit.

Strategies

Not only simple rules and conditions for organizing the game explain the popularity of the Sea Battle game, but also the fact that winning in it is determined not only by luck, but also by the correct strategy and tactics. This is a game of two people, which means that emotions and cunning join the logic. Therefore, a winning strategy involves:

The opponent should never be able to see your playing field.
Consider your opponent's skill and way of playing. For example, if your opponent is a beginner, then you should not place your ships in the corners of the field. Inexperienced ones often start with them, especially with A1. If an experienced and long-time rival will play with you, who already knows that there cannot be in the corners of your ships, then you should break the template and hide a couple there.
Consider the location of your ships. One of the winning strategies is considered to be the location of large ships compactly in one place, and unicellular ships scattering away from each other. Then the player, having quickly found large ships, will spend a lot of time looking for small submarines. This will give you time and a chance to win back.

Winning tactics

There are a few simple tricks related to correct game tactics.

It is imperative to record the opponent's moves on your field, and all your moves on the second playing field. Not only hits are indicated, but also misses. Someone makes it with dots, someone with crosses. This will avoid re-firing empty squares and conflicts in case of any errors.

If the opponent's ship is "killed" in a sea battle, then the cells surrounding it are marked as empty immediately. After all, we know that the rules prohibit the placement of ships in them. This saves you time. In this case, the most profitable shot at the battleship. Its destruction opens eighteen cells at once, almost a fifth of the field.

The shooting tactics of the players can also be different. You can shoot by making moves diagonally. This makes it more likely to hook large ships. You can, in search of a profitable battleship, shoot through three cells to the fourth. After the first hits, the choice of moves is determined based on what begins to appear on the enemy playing field.

The tactic of fighting the popular fraud, when the opponent places the last single-deck ship in the last free cell during the game. In order to make such a deception impossible, the field and ships are drawn in one color, and the shots are marked with another pen or pencil.

Today the game Sea Battle exists both in the form of a tabletop factory set and in the form of a computer game, but playing on a simple piece of paper in a box is still exciting.

We play "Sea Battle"

Required good imagination. And now you just need to log into the social network, launch the application, and vivid pictures of battles will appear right in front of you. But how to win a sea battle? It turns out that there are several ways to confuse an opponent and quickly score several thousand points.

End-to-end verification

A set of ships always occupies 17% of the field area. And it is likely that some of the figures will be located on one of the diagonals. Therefore, for a seed, shoot the lines that connect opposite corners. it main idea of \u200b\u200bthe planhow to win sea battle online.

How to win a naval battle? We are looking for ships

When one of the shots hits the spot, try to determine the type and position of the ship. To do this, feel the four cells around the covered target. Better yet, this is a hint how to win naval battle in classmates - use the so-called knight's move. That is, check three squares in a row horizontally (vertically), and then fold to the side. The meaning of this is - by "drawing" two letters G, you will scan more than 30% of all cells.

Do I need to hide ships?

Surprisingly, most of the fleet should be displayedcrowding large figures at the border of the field. It will be extremely difficult for an opponent who is also wondering how to win at, it will be extremely difficult to find one- and two-deck bots. Yes, some of the ships will leave, but after a short triumph, your opponent will start shooting past, often passing the move.

And how to win a naval battle in classmates? Depending on which application you turn on, both a bot and a person can appear on the other side of the screen. And then, as you understand, the strategy needs to be selected individually.

Summing up

Probably, you yourself, having mastered the free application, will invent new ways of how to win the sea battle online. However, the old, tried-and-true tools described above shouldn't be discounted either. These strategies, if used skillfully, will help defeat any virtual player.

Sea Battle is a popular game with simple rules. Asking the question of how to win a sea battle, the player will always be helped by a winning attitude and the right strategy.

First you need to remember the rules of the game. The player has ten ships at his disposal: 1 four-deck battleship, 2 three-deck cruisers, 3 double-deck destroyers and 4 single-deck boats.

The fleet is positioned on the field so that the vessels do not touch each other. Next you need to draw the same field for the enemy to mark your shots. On a miss, the move goes to the opponent. The winner is the one who sinks the opponent's fleet first.

You can agree with your opponent about the ability to change the shape of the ships, "bend" the ships. So the ships on the field will look like the parts of "Tetris", it will be more difficult to sink them, and it will become more interesting to play.

A successful alignment in the game does not depend on chance, but on two important components of the strategy:

placement of own ships;
the best option for shooting at the enemy's fleet.

Location of ships

There are several tactics for deploying your fleet. Whether tactics work or not will depend on the opponent's shooting tactics. In any case, a haphazard arrangement of ships will not lead to a known good result.

"Half of the field"

The first tactic is to place the battleship, cruisers, and destroyers on the same half of the field.

But four boats are located on the opposite side, as a result they become practically invulnerable. The enemy will have to make a lot of shots before he hears "Killed!"

"Diagonals"

The first thing most players do is shoot the field along two diagonals - from corner to corner. If the opponent is of this type, the second tactic will be very useful. All ships are positioned so that they will not be hit by diagonal shots.

The nice thing about this tactic is that it can be used in conjunction with another formation tactic. A well-thought-out layout of your fleet is half the battle.

"Shores"

The third tactic can be applied in two ways. The first way is simple - place all your ships around the edges so that the middle of the field remains empty. While the enemy will randomly fire, wondering where all the ships have gone, you can calmly search for his fleet.

Such tactics may not be justified, especially when the opponent guesses what the chip is. If the secret of the location of the ships is revealed, the opponent will sink the entire flotilla of the player in the minimum number of moves.

The second method is more thoughtful and similar to the "Half Field" tactic. To do this, place the battleship, cruisers and destroyers along the banks, but scatter the boats throughout the field.

Placing large ships in this way leaves a lot of free space for boats. There is no strategy for finding boats, and the opponent will fire at random, losing precious moves.

Even if the enemy is not going to fire on the field diagonally, shots in the corners cannot be avoided. Thus, it is better not to occupy cells A1, A10, K1, K10. It is also undesirable to place ships in the very center of the field - D5, D6, E5, E6.

The player's strength and invulnerability are precisely in single-deck boats - although they can be destroyed with one shot, for this you need to find them first. The more reliably they are hidden, the more chances you have to win the game.

Destroying the enemy

There are also several tactics for destroying an opponent's flotilla. Some of them overlap with ship placement tactics.

"Diagonals"

Many people will put at least one ship on this periphery. Therefore, we arm ourselves with patience and methodically shoot the diagonals, alternating for a variety of directions of fire.

The player in the picture neglected the tactics of correct positioning and paid for it with the loss of the battleship and boat.

When the diagonals are shot through, you can continue shooting in a checkerboard pattern.

"Chess"

From the name it is clear how you need to "clean up" the opponent's field. The good thing about this tactic is that it allows you to quickly find battleships, destroyers and cruisers. However, you will have to sweat with the search for boats.

"Locator"

The tactics are a bit like Chess, however, with their own twist. To use this tactic in the corners of the field, mentally or directly with a pen, mark four squares measuring 4 by 4 cells.

You need to fire them diagonally. As a result, the field will be divided by a white cross. Given the number of ships that have already been sunk, finding the rest will not be difficult. In the picture, the player discovered six ships thanks to the Locator tactic.

"Crow's Feet"

The destruction of a battleship gives the player the advantage that he will have to fire a much smaller number of cells than if he destroys, for example, a destroyer. Having sunk the battleship, there will be from 6 to 14 cells around it, which the player no longer needs to fire.

So, to find the battleship, you can use the Crow's Feet tactic. To do this, mentally divide the field into squares of 4 by 4 cells and make four volleys in each square.

In the first top square, the player fires a volley at A3, B4, B2, D1. Then it remains to repeat the pattern in other squares. The battleship will be found in a maximum of 24 shots.

After the battleship has been found and sunk, you can proceed to the attack on the three-deck cruisers. To do this, in each square you need to make only two shots.

In the first square, shoot at B1 and G3, and do the same with the rest of the minifields. The eleventh shot is guaranteed to kill the cruiser.

To knock out a double-deck destroyer in each square, you need to make three shots. Shoot at A2, B3 and B4 in the first square. Repeat the triple move in the remaining squares. In the end, the most difficult thing will remain - the search for boats. Unfortunately, there is no tactic for finding them. The player will have to rely on his intuition or the psychology of the opponent.

There are a few more rules for quickly destroying an opponent's fleet:

The "Sea Battle" rules do not necessarily prescribe finishing off the ship after the first "Wounded!" However, it is better to bring the matter to the victorious "Killed!" After all, the courts cannot stand close to each other.
When shelling the enemy's field, you do not need to stagnate in one place. The shots should cover as large an area as possible. Keeping in mind the tactics he likes, the player can “walk” around the field, instead of continuing to fire at the wrong area.
If the opponent uses some kind of tactics, and does not randomly shoot at random cells, you need to turn on the head. Sometimes, looking closely at the moves of the enemy, you can guess how he placed his ships.
Often playing with one opponent, the player can memorize his deployment and firing tactics, using the experience gained to improve his own strategy.

To practice the skills of playing "Sea Battle" and test tactics, you can use online services. The advantages of gaming sites are high speed and low resource consumption. Having worked out and improved his strategy, the player will be able to show off his knowledge in a game with a live opponent.

There is no one hundred percent way to win in "Sea Battle", in the end it all depends on the strategy of the enemy and the player himself. For this reason, Sea Battle remains a fun way to pass your time.

A simple and addictive game that has been known since childhood is sea battle. The rules of the game are not very complicated, anyone can remember them. Adults and children like the sea battle, you can play it anywhere.

Sea Battle game rules

The essence of the entertainment lies in the fact that two players take turns calling certain coordinates on the opponent's map, which is unknown to them. The named point must hit the ship or part of it. The task of each player is to sink all enemy ships first. There are several options for such a game today:

On the paper. This method is considered a classic entertainment option. It lets you play anywhere. A checkered notebook or one leaf (not even lined) is suitable for battle.
Desktop. The first version of such entertainment appeared more than 80 years ago. The board game sea battle was notable for its volume, color. Over time, many variations appeared with different numbers of ships, different sizes of fields.
On the computer. Modern gadgets can be easily turned into a battlefield of ships by downloading and installing the required application. There are online options. Features: the selected points are fixed automatically, there is a voice acting that adds reality to what is happening.

Field

To understand how to play naval combat, you need to understand the basic concepts. You need to start by drawing your playing field. It is a coordinate plane, a 10 by 10 square. Each side has its own definitions: the horizontal one is numbered from top to bottom, the vertical one - by letter designations. The letters of the Russian alphabet are used from "A" to "K" or from "A to" I "if" E "and" Y "are skipped. Often, instead of letter designations, the words "Snow Maiden" or "Republic" are used. They consist of ten letters, which corresponds to 10 squares on the playing field.

Next to "your" field you need to draw "someone else's", which has the same dimensions and coordinates. This is the site for the enemy's flotilla. The field is empty, it is used to mark your opponent's moves and "hits". Given that there are several options for the coordinate system, it is recommended to agree in advance which one will be used. Next, you need to arrange the ships.

Number and arrangement of ships

There is a certain layout of ships on the playing field. A ship consists of several decks or pipes (hence the name, for example, "double-deck" or "double-pipe"). On the playing field are located:

1 four-deck, ship, battleship, - a row of four cells,
2 three-deck, cruisers - rows of 3 cells;
3 double-deck, destroyers, - rows of 2 cells;
4 single-deck ships, torpedo boats, - 1 cage.

In the classic game, you need to draw ships on the playing field according to the rules. For example, all ships by sides or corners cannot touch each other. There are variants of the game, when ships are placed with the letter "G", squares or zigzags, touching with corners is not prohibited. There are also battles with a different number of ships or their structure, for example, a five-deck (aircraft carrier), several four-deck ones. When using a larger number of ships, a different form of the field is used, measuring 15 by 15. It is necessary to decide on the choice of game in advance.

Game progress

It is necessary to play naval combat on paper in accordance with certain rules. The instruction defines the conditions and order of moves:

Initially, it is chosen who will walk with the first. To do this, the players throw lots.
When making a "shot", the player names the coordinates, for example, B3.
If there is nothing in the cage, the opponent says "by". The ship is located according to the named coordinates, then "wounded" - if it was hit, "killed" - when completely destroyed.
The cross marks the hit on the enemy ship. With such a successful shot, according to the rules, the player moves a second time. The right to move is passed to the second player if the blow fell on an empty field.
The winner is the one who is the first to sink all ships of his opponent.
At the end of the game, opponents can demand from each other playing fields for verification. The loser will be the one whose fields are filled in incorrectly. The victory goes to the one who fought an honest fight.

There are certain limitations in the game. The game can be ended earlier if there is a violation of the rules. Gross violations are:

Incorrectly Drawn Margin — Number of vessels exceeds the required number, wrong side dimensions or coordinate system.
One of the players spied on the location of the ships from another.
Skipping a turn due to inattention.

Winning strategy

An easy battle isn't all about luck. To achieve victory, there is a strategy and tactics for playing sea battle. It is as follows:

The sheet with the drawn field must be held so that the enemy cannot see.
For convenience and reporting, it is recommended to mark enemy shots with dots.
The most vulnerable ships are the battleship and the torpedo boat. The first one is very large and therefore easy to spot. Torpedo boats are small and hard to find in the field, but they sink with one blow.
Beginners often aim at the corners of the game square, so it is not recommended to draw them there.
Experienced players are advised to immediately come up with the layout of the ships on the field. Good results can be achieved by arranging the flotilla units according to the scheme. For example, by collecting cruisers and battleships in one place, and placing boats and destroyers in a chaotic manner.
Flotilla shooting techniques can be different. To quickly destroy the battleship, it is recommended to start searching for it diagonally. You need to shoot at the squares at 4, after 3 cells. Then you need to move in descending order: look for three-deck, double-deck and single-boats.

If you have not tried to play Sea Battle, then most likely you have been abandoned by aliens. Because in the to-do list of a Russian schoolchild, the game "Sea Battle" is marked as "a sure remedy for boredom" and today is the time to make sure!

Let's learn how to play Sea Battle online - in Russian for free and without registration. You don't even need an opponent - fight the computer! Let's start with the basics.

Rules how to play sea battle on a piece of paper

The original Battleship is a classic board game for tactics and attention, where two players were supposed to draw 2 10 × 10 grids with letters horizontally and numbers vertically on a piece of paper in a box. The first is a field for placing your fleet of 10 ships so that the enemy cannot see. The second is a battle plan with a mark of moves towards the enemy.

The fleet consists of:

1 "four-deck battleship";
2 "three-deck cruisers";
3 "double-deck destroyers";
4 "single-deck boats".

When placing, the distance of 1 cell must be taken into account (ships should not touch either sides or sterns).

Each player in turn calls the other the possible coordinates of the target and, according to the answers: "by", "wounded" or "killed", he orients himself in the situation - trying to build a strategy for destruction and analyze the opponent's plans. Hitting the ship is awarded the right to make one more move.

In the online version of naval combat, you do not need to draw anything and mark the coordinates of each point too - the computer will do this automatically and complement each move with funny animation. You start playing first and can follow the statistics of the moves.

How to arrange ships to win in Naval Battle

The most vulnerable targets are four-deck and three-deck ships, which are easy to spot if you shoot at intervals of three squares. Usually they are placed far from each other, but in the same diagonal, at an angle. Bypass this rule - place ships more closely - all large ones vertically or horizontally.

Consider the mandatory distance between occupied positions: there can be no other targets within a radius of one cell from the wrecked ships.

Try to reduce the area of \u200b\u200boccupied areas and confuse the enemy - place the smallest ships "in plain sight".

The enemy will certainly shoot near the point of impact in order to determine whether the wounded combat ship is located vertically or horizontally. To buy time and provoke mistakes, change the spatial placement of the same type of ships and use the edge of the grid to the maximum.

Think like the enemy. In most cases, enemy ships are located at a distance from each other, in order to complicate the task of identifying them, scatter them, but remember about the placement rules (there can be no other occupied positions within the radius of one cell).

Control

Use the computer mouse to drag the battleships onto the grid by clicking on the ship and holding the mouse down.

To change the position in space (turn horizontally or vertically) - hold Ctrl while the boat is out of the grid and only then click and drag.

In Game "sea battle" two people play, who in turn call the coordinates of the ships on the enemy map. If the coordinates are occupied, then the ship or part of it is "drowned", and the one who got in has the right to make one more move.

The game takes place on a field of 10x10 cells of each player, which houses a fleet of ships. Contours are usually numbered from top to bottom, and verticals are labeled from left to right. In this case, the letters of the Russian alphabet are used from "a" to "k" (the letters "e" and "y" are usually skipped) or from "a" to "and" (using the letter "e"), or letters of the Latin alphabet from " a "to" j ". Sometimes the word "republic" or "snow maiden" is used, since in these 10-letter words not a single letter is repeated. Since there are various options for specifying the coordinate system, it is better to agree on this in advance.

The fleet consists of

* 1 ship - a row of 4 cells "four-deck"

* 2 ships - a row of 3 cells "three-deck"

* 3 ships - a row of 2 cells "double-deck"

* 4 ships - a row of 1 single-deck cells.

When placed, ships cannot touch each other at their corners.

The decks of ships should be built "in line", not bends. The main thing: you cannot build the decks of one ship diagonally.

Before the start of hostilities, players throw lots or agree who will go first.

The player making the move makes a shot - names out loud the coordinates of the cell in which, in his opinion, the enemy ship is, for example, "К1!" ...
If the shot hit a cell that is not occupied by any enemy ship, then the answer follows: "Pass!" and the shooting player puts a dot on someone else's square in this place. The right to move passes to the opponent.
If the shot hit the cell where the multi-deck ship is located (larger than 1 cell), then the answer is “Wounded!”. The shooter puts a cross on a foreign field in this cell, and his opponent puts a cross on his own field in this cell. The shooter is entitled to one more shot.
If the shot hit the cell where the single-deck ship or the last unaffected cell of the multi-deck ship is located, the answer is "Sunk!" or "Killed!" Both players mark the sunken ship on a sheet. The shooter is entitled to one more shot.

The winner is the one who sinks all 10 enemy ships first. The loser has the right to ask the opponent to examine the playing field after the end of the game.

Violations

The player has his own field drawn incorrectly: the number of ships does not correspond to the rules; ships touch each other; wrong field sizes and wrong coordinate system.

The player made changes on his playing field that were not provided for by the rules of the game (during the game, you can only put dots and crosses and only according to the rules), for example, he completed the missing ship, the player peeped the location of the enemy ships or missed his turn.

An incredibly popular paper game. And although now there are special play sets for "Sea Battle", as well as a lot of computer implementations, the classic version on a piece of paper remains the most popular.

The goal of the game is to sink enemy ships before he has time to sink yours.

Rules of the game "Sea Battle"

Two players are playing. Each of them needs a piece of paper (preferably in a cage), pencil or pen. The game begins with the preparation of the field. Two squares of 10 × 10 cells are drawn on a piece of paper. On one of them their ships will be deployed, in the other they will "fire" at enemy ships.

The sides of the squares are signed with letters horizontally and numbers vertically. It is necessary to agree in advance which letters will be written (the main disputes arise as to whether or not to use the letter "E"). By the way, in some schools, instead of a boring alphabet, they write the word "REPUBLIC" - it just contains 10 non-repeating letters. This is especially useful for those who have never mastered the alphabet.

Arrangement of ships

Next, the placement of fleets begins. The classic rules of naval combat say that there should be 4 ships in one cell ("single-deck" or "one-tube"), 3 ships in 2 cells, 2 - 3 cells each and one - four-deck. All ships must be straight, curved and "diagonal" are not allowed. Ships are located on the playing field in such a way that there is always a gap of one cell between them, that is, they should not touch each other either by their sides or corners. In this case, ships can touch the edges of the field and take up corners.

When the ships are placed, the players take turns making “shots”, naming the squares by their “coordinates”: “A1”, “B6”, etc. If the cell is occupied by a ship or part of it, the enemy must answer "wounded" or "killed" ("sunk"). This cell is crossed out with a cross and one more shot can be made. If there is no ship in the named cell, a point is placed in the cell and the move goes to the opponent.

The game is played until the complete victory of one of the players, that is, until all the ships are sunk.

At the end of the game, the loser can ask the winner to look at his ship placement.

Mastery

If you think that naval combat is a game based solely on luck and luck, then you are wrong. In fact, it contains both strategy and tactics, which we will talk about in the conclusion. So - about the tricks as well as various honest and not very fair methods of playing sea battle:

First of all (and this is the most important thing!), You need to keep your sheet with ships so that the enemy cannot spy on your location;
Be sure to keep track of your and others' moves, marking them with dots. This will exclude shots at the same cells;
After sinking an enemy ship, also surround it with dots so as not to shoot at places where there are obviously no ships;
Do not put ships in the corners of the field: usually beginners shoot at them first. However, exceptions will be discussed below;
It is necessary to develop a strategy for placement. A good result is an uneven distribution of ships: collect all the "large" ships in one or two dense groupings, and hide the remaining "single-decks" separately in secret places of the playing field. In this case, the enemy will quickly calculate and defeat the grouping of large ships, and then will search for the remaining small ships for a long time;
After killing a large ship, the enemy surrounds it with dots. This means that, having found a “four-deck”, the enemy immediately opens (4 + 1 + 1) * 3 \u003d 18 cells (that is, 18% or almost 1/5 of the field). "Three-deck" gives 15 cells (15%), "double-deck" - 12%, and "single-deck" - 9%. If you put the "four-deck" against the wall, then it will open only 12 cells (10 for a three-deck, 8 for a two-deck). If you put the "four-deck" in the corner, it will only open 10 cells (8, 6 and 4, respectively). Of course, if the enemy realizes that all the ships are on the edge, he will quickly sink them. Therefore, it is best to use this advice in conjunction with the previous one.
Shooting tactics can also vary. However, the best way to start the destruction of enemy ships is to search for a "four-deck". To do this, you can shoot on the diagonals, or draw a diamond, or shoot through 3 cells to the fourth. As soon as a four-deck ship is found, we are looking for a three-deck one, then two. Of course, in the process of searching "every little thing" will come across and make adjustments to the plans.
And here is the dishonest way: to arrange all the ships, except for the last single-deck (it will act as the submarine "Elusive"). And he will be placed (and killed) only in the last remaining cell. Dealing with this is easy enough: have the players arrange the ships in one color, and fire in another. For example, players can have pens or pencils of different colors and, after placing the ships, simply change the pens.

Sea Battle is a simple and addicting board game that doesn't require any special knowledge or special tools. To play together with a friend or family member, just take two squared sheets and two pencils. The game not only allows you to have fun, but also contributes to the development of intuition, strategic thinking. How to play naval combat at home?

Rules of the game

The essence of the sea battle game is that two people take turns blindly calling the coordinates on the enemy's map (on a piece of paper in a box). The named point must destroy the ship or hook part of it. The sooner the player sinks the opponent's fleet, the faster he will win.

Playing field

It is a sheet in a box, on which a square of 10 x 10 cells is drawn. Each side of the figure has its own coordinates. The vertical side is numbered from top to bottom (from 1 to 10). Horizontal from left to right is designated by letters of the Russian alphabet (from "A" to "K", omitting "E" and "Y"). The ships are placed in the drawn square.

Sometimes, instead of letters, the words "Republic" or "Snow Maiden" are used.

The opponent's field is drawn on paper next to his own field. It must have identical coordinates and dimensions. The plane remains free and is used to mark your shots.

The number and location of ships in the sea battle game

Submarines are made up of multiple tubes or decks. The playing field must accommodate:

1 four-deck battleship - 4 cells;
2 three-deck cruisers - 3 cells each;
3 double-deck destroyers - 2 cells each;
4 single-deck ships - 1 cell each.

The ships should be placed according to certain rules. They cannot touch each other at their corners or sides. There must be at least one empty cell between them. It is equally important that they are located only horizontally and vertically.

There are options for naval combat with a different arrangement of ships - the letter "G", zigzags or squares. Perhaps their other structure and number. For example, 2-3 four-deck and 1 five-deck (aircraft carrier). When using a larger number of ships, a different field size (15 × 15) will be required.

Conditions and order of moves

The players draw lots to choose who will go first. When you shoot, you name the coordinates (letter and number). For example, B8. The opponent looks at the playing field with his submarines and replies:

past;
injured;
killed.

In the first case, he makes it clear that you are on an empty cell. The move goes to the opponent.

The second option means that you are in a multi-deck vessel (consisting of 2, 3 or 4 cells). Mark this place on your map. You are entitled to the next shot. To finish off someone else's ship, use the nearby coordinates. For example: B7, B9, A8 or B8. You can temporarily leave alone the wounded ship and look for another. The turn lasts until you miss.

The third option suggests that the enemy's submarine is destroyed. If this happened with a single shot, then it was single-deck (occupied one cell). If the ship is killed on the second turn, then it was double-decked, etc. After the destruction of the ship, you can walk until you hear the answer "by".

Strategies

Well-planned tactics will help to win the sea battle game. The winning strategy offers:

Mask carefully. The companion should not see your board on a checkered piece of paper.
Consider the opponent's way of playing and skill. For example, if this is a beginner player, then you should not place your fleet in the corners of the field. Beginners start with them. With an experienced competitor, it is better to break the mold and hide two or three ships in such a place.
Consider the placement of your ships. Single-celled vessels can be scattered, far from each other. Large - compact in one place. The partner will quickly find large objects. However, he will spend much more time looking for small submarines. This will give you a chance to win back.
Celebrate your shots. Place crosses in the right empty square. This is not how you name these coordinates a second time. Record both hits and misses. This will avoid conflicts in case of any errors.
Cross out the cells around the destroyed enemy ship. The rules prohibit building ships in them. This will save you time.
Shoot while moving diagonally. This increases the chances of knocking out large submarines. In search of a battleship, you can walk through three cells to the fourth.

What not to do

If the rules are not followed, the sea battle game can be ended earlier. The following are considered unacceptable violations:

Skipping turn due to carelessness.
Incorrectly drawn margin: incorrect coordinate system or side dimensions of the square.
The number of vessels exceeds the required number.
One of the players spied on another's submarine placement.
Hiding hits.
The last single-deck ship is placed by the opponent in the last free cell during the game. To avoid deception, draw the ships and the field on a piece of paper in one color, and mark the shots with another pencil or pen.

Sea battle is a pretty addicting game. She is familiar to many adults and children. Its rules are simple, anyone can remember them. You can play almost anywhere. All that is needed for this is a piece of paper and a pen.

Indulging in tic-tac-toe games, cities in words and sea battle with passion, children continue the tradition of their parents' hobbies. But what is their surprise when they find out about it. It seems to them that everything they play is their own inventions, without realizing that everything new is, as a rule, well forgotten old, transformed and adapted to new possibilities.

Good old sea battle games

If earlier naval battles took place on a piece of paper, today they unfold on digital media screens, although sometimes they look authentic with the original. The rules of such toys have also been preserved, and this attracts the attention not only of the younger generation, but also of their parents, brought up on these entertaining and intellectual products. It's nice to plunge into childhood and play sea battle online. Now this lesson is available even when there is no one to share the moments of returning to the days gone by. Artificial intelligence easily takes over the function of your opponent and makes moves no less skillfully.

Simple rules of the game

In front of you you see two squares, one of which is your military training ground. Both of them have the same dimensions and markings - 10x10 cells on each side, as well as numbers and letters.

The right or left side assumes the order of the numbers from one to ten, from top to bottom.
Accordingly, the top or bottom side is marked with letters from right to left, AK.
Within the field, each player places ships and keeps their deployment secret.
Those ships that contain more than two cells can be refracted at right angles to either side.

According to the conditions, each participant must have a standard presence of combat units:

four-deck ship - one;
three-deck - two;
two-deck - three;
single-deck - four.

The name of the ships comes from how many cells each contains. To play sea battle online, remember the original version, and it will become clear to you what's what.

In order to make a shot at an enemy object, name the estimated coordinates, for example, K-2.
If the shot is successful, the defeated must report whether you killed his ship or only wounded him.
Until then, you can take steps in a row until you hit the target, but as soon as you miss, this right goes to your opponent.

As you can see, online sea battle games differ only in that there is no need to draw squares and markings yourself, because the developers have already done this for you. And you don't have to have a playmate on hand to enjoy the process. You can choose a new version of the toy, or turn to one that resembles a sheet of paper and a drawing with a ballpoint pen, and this will help you indulge in nostalgia for your pleasure.

The revival of slot machines in virtual spaces

Adult gamblers should remember how in Soviet-era cinemas there were slot machines in the waiting room. People, while waiting for an invitation to the hall to watch a movie, could while away the time by fetching a pen or a keychain from the bowels of a box using an iron pliers, shoot at targets in a virtual shooting range or play sea battle. Ships were sailing on the horizon, and you, looking through a special binocular window, pointed your sight at them and, pressing a button, tried to knock them out. When the shot reached its target, the ship sank to the bottom, and a red flash illuminated the screen. If you want to experience some forgotten sensations, get ready for a surprise, because we have exactly the same game! In addition, online sea battle games offer modern versions of the process.

Going to sail the seas, decide for yourself - you will become a pirate or will bravely fight against sea robbers.

Today computers - both stationary and laptops, tablets and PDAs - play a huge role in our life. With their help, people write, read books, draw. The reality around us is gradually being computerized, creating new opportunities and transferring old ones into a virtual format. That is why board, card and logic games are so popular, the action of which is transferred to computer monitors. People quickly learn new things, so they are happy to play chess, poker or "in the cities" in a new way. And of course, there are many who want to play sea battle online. We all remember this game from school. The teachers fought in vain with her - after all, there is simply no better way to dispel boredom in a lesson you are not interested in. All you need is two checkered sheets, pens and the ability to speak quietly. “A1 - wounded… D8 - killed” - these encrypted messages marked victories and defeats in a game that seems simple only at first glance. After all, here players need a good memory and visualization skills to imagine the location of ships on the enemy map. As well as logic and imagination to arrange your fleet in the most unexpected way. And if checkers and even more so chess were considered games for clever people, then everyone played in sea battle - boys and girls, excellent students and poor students, kids and high school students.

There were also tabletop versions of the game in the form of a field on which you can place pieces-ships. But there was no need for them - you can always draw a piece of paper in a box and immediately start fighting. Modern sea battle makes it much more comfortable to play online. For example, it marks the places where, according to the rules, there cannot be enemy ships, so that you do not waste your shots. And the visual component makes the game more fun - on the squares of the field you see not crosses and dots, but real battleships, cruisers, destroyers and submarines. In addition, online sea battle makes it attractive to a very wide audience. For example, for those who love logic games, but do not want to learn new rules. Here he is given the opportunity to play his favorite game in a new, more perfect format. Thus, online sea battle games turned into a modern and popular game, breathed a second wind into it and helped to find new fans. A generation raised in the fascinating world of computer games. Those who have no idea how you can play exciting games using a simple piece of paper and a ballpoint pen.

It's pretty easy to tell how to play naval combat - the rules are simple, no special skills or adaptations are required in the process. This game is often chosen for fun and relaxation. Such leisure will help develop strategic thinking and logic.

The game requires only 2 sheets of paper and pencils or pens. The playing field is a square with a side of 10 cells. Letters from A to K are written horizontally above the field ("E" and "Y" are skipped), vertically - numbers from 1 to 10. Each player draws 2 squares:

one has his own fleet;
the second is left empty - this is the opponent's field.

Opponents do not see each other's fields.

The classic version of the game.

Ships are placed inside the square. You need to accommodate:

4 single-deck 1 cage vessels;
3 double-deck destroyers, 2 cells each;
2 three-deck cruisers, 3 cells each;
1 four-deck battleship occupying 4 cells.

The figures should not touch each other by sides or corners, partially or completely coincide. In the classic version of the game, all ships are placed vertically or horizontally. There are, however, varieties in which placement with the letter "g" or a square is allowed.

Naval battle variations

Traditional naval combat can be played not only on paper, but also on your phone, tablet or computer. In addition, there are special sets for this board game. With their help, you can make the fight more realistic.

Tabletop sea battle.

There are options with larger fields. They can accommodate larger ships. Often these versions add a 5-cell liner. As an option - to play sea battle three or four, having gathered in a large company.

The "Volley" is also a complicated version. The size of the play area remains the same, but the size and number of ships change. You need to draw:

1 liner of 5 cells;
2 destroyers from 2 slots;
1 cruiser out of 3.

A person makes 7 shots per turn (1 for the destroyers, 2 for the cruiser, and 3 for the liner). The opponent does not specify which of the moves was effective. Instead, it states how many hits were made on which ship (for example, "1 in the liner" or "2 in the cruiser"). When any of the ships is sunk, you need to immediately report. At the same time, the number of shots will also decrease in accordance with the lost ship.

You can add 1 or more minutes to the game. Such a figure is indicated on the field with a circle. If the enemy shoots at an explosive element, he must report the coordinates of one of his cells containing the ship. In this case, the cell will not die immediately. The owner of the mine can shoot it later. The explosive device must not come into contact with vessels (including their corners).

On a large field 16 * 16, you can increase not only the number of ships, but also the number of mines. At the same time, a minesweeper is introduced into the game. On the playground, it is marked as a triangle. If a player gets into an enemy minesweeper, he will have to tell the enemy where one of the mines that have not yet been opened is located. A cage with such an element should not come into contact with ships, mines and other minesweepers.

Naval combat rules

The goal of the game is to drown all the opponent's combat units. The player chooses which cell he wants to check, after which he first names its letter, and then - the number (for example, "E8"). If the second player has a ship in such a cell, the person answers "hit" or "killed". The attacker puts a cross in the right place on the drawn empty field. After being hit, the person gets the right to one more shot.

When he names a cell that the opponent has empty, he will answer "by". After that, the turn goes to the second player. The winner is the one who is the first to discover all of the opponent's ships.

The winner is the one who is the first to "trim" the enemy ships.

How to play sea battle on a leaf

The easiest way is to use squared notebook sheets. If you take landscape ones, you will have to draw the field using a ruler. You must first agree on the letter designations. Some players prefer to use words of 10 non-repeating letters (for example, "Republic" or "Snow Maiden").

Field creation

You can use a piece of paper from a notebook in a box, or you can independently draw 2 sites measuring 10 * 10 for each of the players. In the first, they place their own flotilla, the second is required to fix the shots fired, hits in the enemy combat units.

You can draw a larger field, add larger vessels. Such options are suitable for professionals who have mastered the simpler version.

Number and location of ships

Participants of the classic version of the game "Sea Battle".

In the classic version, each player has a fleet of 10 combat units, differing in length. Total should be:

boats - 4 ships, 1 cage each;
destroyers - 3 of 2 cells;
cruisers - 2 figures out of 3;
battleship - 1 ship out of 4.

The pieces must not intersect or touch, including diagonally. By default, ships are drawn in the form of a straight stick, but by agreement of the participants, they can be bent or made a square. In this case, it will be more difficult to calculate the position of the enemy battleship.

Order of moves

You can agree on who goes first, or draw lots. The right to move is passed to the second player after a miss. If a person hits the target, he continues to walk.

Game strategies and tactics

Often large units are located on one half of the field, and small ones on the other. While cruisers, battleships and destroyers will be easy to spot, it will be difficult for the enemy to sink the boat. It is better if single-deck vessels are located far from each other. So the opponent will spend a lot of time looking for them, due to which there will be an opportunity to recoup.

Effective and diagonal shooting. With their help, large ships are found. Experienced naval combatants take this into account when deploying their own flotilla.

The player can place all units around the edges. Then the enemy will have to spend a lot of shots to check the empty territory inside the square.

Your opponent's tactics need to be considered when placing your ships. If the enemy is a beginner, it is better to refrain from placing units in corner cages. Novice players often check them first. If you are playing with an experienced one, you can hide 1-2 small boats in the corners. Due to the formed pattern, the corners will be checked last.

Examples of the location of ships.

Any moves of the opponent should be recorded on their own field. Indicate each of your actions on the second. Not only hits, but also unsuccessful moves are noted. This will prevent you from re-shooting an empty square, preventing mistakes and possible disagreements.

You need to carefully hide your field from the second player, so that he could not spy on and cheat.

When the enemy ship is sunk, you should mark the cells surrounding it with dots, as already fired. According to the rules of the game, it is forbidden to place ships in them, so it is not necessary to spend moves on a check. Sinking a battleship is most beneficial, as this will open 18 cells at once. If you place a large ship near the wall, the number of open cells will be reduced to 10.

Forbidden tricks

Often, players do not put 1 boat until the last one. It is drawn already during the game in the last free cell. To prevent such fraud, you first need to draw a field and ships with a pen of one color, and then use ink of a different color during the game. At the end, you can ask the enemy to show the field. If he cheated, the deception would quickly be revealed.

You can't peep on your opponent. It is better to sit at a distance from each other so that it would be impossible to peep unnoticed.

It is prohibited to change the number or size of ships. You can not violate the rules of placement. Dishonest players can position boats so that they are in contact with the battleship at an angle. To prevent such fraud, arrange in advance to show each other the field after the game ends.

You cannot hide hits. In addition, it is prohibited to change the size of the site. It is necessary to agree in advance on the lettering so that the cells have the same coordinates for both participants in the gameplay.

You can not skip both your own and enemy moves.

As a rule, you can learn to play sea battle in one evening. When you get bored with the traditional look, move on to the harder options.
