Sea battle table printable. How to play Battleship: rules

A couple of days ago, I was surprised to learn that some of my friends do not know how to play sea battle. Those. They, of course, know the rules, 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 improve 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 listed ships must be placed on a square field of 10 by 10 cells, and the ships cannot touch either the 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” (the letters “Y” and “Y” are skipped).

An enemy field of similar size is drawn nearby. If there is a successful shot at the enemy ship, a cross is placed on the corresponding cell of the enemy field and a second shot is fired; if the shot is unsuccessful, a dot is placed in the corresponding cell and the turn goes to the enemy.

Optimal strategy

There is always an element of randomness in a naval battle game, but it can be kept to a minimum. Before moving directly to the search for the optimal strategy, it is necessary to voice one obvious thing: the probability of hitting an enemy ship is higher, the fewer unchecked cells are left on his field, similarly, the probability of hitting your ships is lower, the more unchecked cells are left on your field. That. For effective game 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 notation will be used:

Optimal shooting

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

In accordance with the notation adopted above, in the figure, those cells on which unsuccessful shots have already been fired are marked in yellow, cells on which shots ended in hits are marked in red, and cells on which were not fired were marked in green, but it can be guaranteed that the ships there are no ships in them (there cannot be ships there, because according to the rules of the game, ships cannot touch).

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

The third rule follows from the first two: you must first try to knock out the largest enemy ships. This rule may not be obvious to you, but if you think a little, you can easily notice that having destroyed an enemy battleship, we are in best case scenario we will immediately receive information about 14 guaranteed free cells, and by destroying the cruiser, about only 12.

That. The optimal shooting 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 the area playing field 4 by 4 cells in size. If there is an enemy battleship in the area in question, then it is guaranteed to be knocked out in no more than 4 shots. To do this, you need to shoot so that there is exactly one checked cell on each horizontal and vertical line. All variants of such shooting are presented below (without taking into account reflections and rotations).

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

After the enemy battleship is destroyed, it is necessary to begin the search for cruisers, and then destroyers. In this case, as you already guessed, you can use a similar technique. Only now it is necessary to divide the field into squares with a side 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 (fields that you have already shot at when searching for a battleship are marked in green):

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

Optimal placement of ships

The optimal ship placement strategy is in some ways the inverse of the optimal shooting strategy. When shooting, we tried to find the largest ships in order to reduce the number of cells that needed to be checked by guaranteeing free cells. This means that when placing 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, a battleship in the center of the field opens 14 fields for the enemy at once, but a battleship standing in the corner opens only 6 fields for the enemy:

Likewise, a cruiser standing in the corner opens only 6 instead of 12 fields. Thus, by placing large ships along the border of the field, you leave more space 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 left by the time you catch the boats, the harder it will be for the enemy to win.

Below are three ways to deploy large ships that leave plenty of room for boats (in blue):

Each of the above arrangements leaves exactly 60 free cells for boats, which means that the probability of accidentally getting into a boat is 0.066. For comparison, it’s worth giving a random arrangement of ships:

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

In conclusion, I would like to say that you should not spend too much time playing naval battle. I especially want to warn you against playing during lectures. While I was sitting in Wabi-Sabi playing battleship with my girlfriend, a waitress walked by and said that she was quite good at playing because... I practiced a lot in pairs. Who knows what she would have worked like if she had listened to lectures in her time?

P.S. The comments absolutely correctly indicate that there were already similar publications on the hub; it would be wrong not to provide links to them.

Content

Simple and exciting game, which has been known since childhood - sea battle. The rules of the game are not very complicated; anyone can remember them. Sea battle is popular with adults and children; you can play it anywhere.

Rules of the game Sea Battle

The essence of the entertainment is 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 this game today:

1. On paper. This method is considered classic version entertainment. It allows you to play anywhere. A checkered notebook or one piece of paper (not even lined) is suitable for battle.
2. Tabletop. The first version of such entertainment appeared more than 80 years ago. Board game The sea battle was distinguished by its volume and colorfulness. Over time, many variations appeared with different numbers of ships and different field sizes.
3. On the computer. Modern gadgets can easily be turned into a battlefield for ships by downloading and installing the desired application. There are online gaming options. Features: selected points are recorded automatically, there is voice acting that adds reality to what is happening.

Field

To understand how to play sea battle, 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 side is numbered from top to bottom, the vertical side is numbered with letter designations. The letters of the Russian alphabet from “A” to “K” or from “A to “I” are used if “Ё” and “Y” are omitted. 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 a “foreign” field, which has the same dimensions and coordinates. This is a site for the enemy flotilla. The field is empty and is used to mark your moves and your opponent’s “hits.” Given that there are several coordinate system options, 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. The ship consists of several decks or pipes (hence the name, for example, “double-deck” or “double-pipe”). On the playing field there are:

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

IN classic game Drawing ships on the playing field is necessary according to the rules. For example, all ships cannot touch each other with their sides or corners. There are variants of the game when ships are placed in the letter “L”, squares or zigzags, touching the 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. When using more ships, a different field shape is used, measuring 15 by 15. You must decide on the choice of game in advance.

Progress of the game

Playing sea battle on paper must be in accordance with certain rules. The instructions determine the conditions and sequence of moves:

1. Initially, it is chosen who will go with the first. To do this, players cast lots.
2. When making a “shot”, the player names the coordinates, for example, B3.
3. If there is nothing in the cell, the opponent says “by.” The ship is located at the named coordinates, then it is “wounded” - if it is hit, “killed” - when it is completely destroyed.
4. A cross indicates a hit on an enemy ship. With such a successful shot, according to the rules, the player takes a second turn. The right to move is transferred to the second player if the shot lands on an empty field.
5. The winner is the one who sinks all his opponent's ships first.
6. At the end of the game, opponents can request each other's playing fields for verification. The loser will be the one whose fields are filled in incorrectly. Victory goes to the one who fought a fair fight.

There are certain restrictions in the game. The game may end early if rules are not followed. The following are considered gross violations:

1. Incorrectly drawn field - the number of vessels exceeds the required number, the side dimensions or coordinate system are incorrect.
2. One of the players spied the location of the other's ships.
3. Skipping a move due to inattention.

Winning strategy

A simple battle is not based solely on luck. To achieve victory, there is a strategy and tactics for playing naval battle. It is as follows:

1. The sheet with the lined field must be held so that the enemy cannot see.
2. For convenience and reporting, it is recommended to mark enemy shots with dots.
3. The most vulnerable ships are the battleship and torpedo boat. The first one is very large, so it is easy to spot. Torpedo boats are small and difficult to find on the field, but they sink with one hit.
4. Beginners often aim at the corners of the playing square, so drawing them there is not recommended.
5. Experienced players advise immediately coming up with a layout for the ships on the field. Good results can be achieved if you arrange the flotilla units according to the scheme. For example, by gathering cruisers and battleships in one place, and placing boats and destroyers in a chaotic order.
6. Techniques for shooting at a flotilla can be different. To quickly destroy a battleship, it is recommended to start searching for it diagonally. You need to shoot at squares on 4, through 3 cells. Then you need to move in descending order: look for three-decker, two-decker and single boats.

Incredible popular game on paper.

The goal of the game is to sink the enemy's ships before he can sink yours.

Rules of the game " Sea battle»

Two players play. Each of them needs a piece of paper (preferably checkered), a pencil or a pen. The game begins with preparing the field. Two squares of 10x10 cells are drawn on a piece of paper. On one of them they will deploy their ships, in the other they will “fire” on 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 debate arises whether or not to use the letter “Y”). By the way, in some schools, instead of the 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.

Ship placement

Next, the deployment of fleets begins. Classic rules sea ​​battle they say that there should be 4 ships in one cell (“ single-deck" or " single-pipe"), 3 ships with 2 squares, 2 with 3 squares and one with four decks. All ships must be straight; curved or “diagonal” ones are not allowed. The ships are placed on the playing field in such a way that there is always a gap of one square between them, that is, they should not touch each other either with their sides or corners. In this case, ships can touch the edges of the field and occupy corners.

Game

When the ships are placed, players take turns firing, calling 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 you can take another shot. If there is no ship in the named cell, a dot is placed in the cell and the turn goes to the opponent.

The game is played until one of the players completely wins, that is, until all the ships are sunk. At the end of the game, the loser can ask the winner to look at his arrangement of ships.

Mastery

If you think that sea ​​battle- a game built solely on luck and fortune, then you are wrong. In fact, it contains both strategy and tactics, which we will talk about in conclusion. So - about tricks and various honest and not so honest methods of playing sea ​​battle:

• First of all (and this is the most important thing!), you need to hold your sheet with ships so that the enemy couldn't peek your location;
• Be sure to keep a record of your own and other people's moves, marking them dots. This will prevent shots at the same cells;
• After sinking an enemy ship, also surround it with points so as not to shoot at places where there are obviously no ships;
• You should not place ships in the corners of the field: usually newbies shoot at them first. However, exceptions will be discussed below;
• It is necessary to develop a strategy for placement. An uneven distribution of ships gives a good result: gather all the “large” ships into one or two dense groups, and hide the remaining “single-deck” ships separately in secret places on the playing field. In this case, the enemy will quickly identify and destroy the group of large ships, and then will spend a long time searching for the remaining small ones;
• By killing big ship, the enemy surrounds him with dots. So, having found " four-decker", the opponent immediately opens (4+1+1)*3 = 18 cells (that is, 18% or almost 1/5 of the field). " Three-decker"gives 15 cells (15%), " double decker" - 12%, and " single-deck" - 9%. If you place the “four-decker” against the wall, then it will allow you to open only 12 cells (10 for a three-decker, 8 for a two-decker). If you place the “four-decker” in a corner, it will allow you to open only 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 better to use this advice in combination with the previous one.
• Shooting tactics can also be different. However, it is best to start destroying enemy ships by looking for a “four-decker”. To do this, you can shoot diagonally, or draw a diamond, or shoot through 3 cells to the fourth. As soon as a four-deck ship is found, we look for three-deck ones, then two... Of course, during the search process we will come across “all sorts of little things” and make adjustments to the plans.
• Here’s a dishonest way: arrange all the ships except the last single-deck (it will serve as the Elusive submarine). And he will be placed (and killed) only in the last remaining cell. It's quite easy to combat this: let the players place ships in one color and fire in another. It is possible, for example, for players to have pens or pencils of different colors and, after arranging the ships, simply exchange pens.

Still alive. Although it seemed that she should have been forgotten in the era of online entertainment. And, nevertheless, the popularity of battles on notebook sheet still just as big. The only thing that has changed is the method of making the field. Why draw if a printer can handle routine work much faster than a human? So, sea ​​battle field: without registration and SMS.

Naval battlefield

The standard base on which conventional ships are located is a graphed square. As a rule, the game table is divided into 100 cells with coordinates from A1 to K10 or from A0 to K9. And, in order not to draw two grids each time, download a ready-made field for naval battles from our website. The template is completely ready for printing on A4 sheet, and after downloading the image can be immediately output to the printer.

Sea battlefield: advantages of the template

Agree, playing naval battle is much more enjoyable on a neat, beautifully designed field. And most importantly, having a sufficient number of tables in stock, you can fight for a long time without interruption. There is no need to be distracted by drawing the sheet, because there is a printing machine for this. All you have to do is arrange a cunning flotilla, come up with a strategy, and become a champion in naval combat.

You can not draw these fields, but immediately download ready-made ones from this page and print them in A4 format. I suggest larger fields in which the size of one cell is 7.5 x 7.5 mm. The size of the fields is traditionally: 10 by 10 cells.

The first field for the game on a white background. There are no unnecessary graphics, which means less ink will be used when printing. At the bottom of each card there is a graphical hint about the number of ships. Let me remind you that according to the terms of the game, each participant in the battle must initially have 1 four-decker ship (4 squares circled), 2 three-deckers, 3 two-deckers and 4 single-deckers. 1 deck = 1 circled square. When building ships, they should not touch at the corners or sides.

Not everyone wants boring white naval battle cards. Therefore, I present to your attention a template for a naval battle with a themed background. Cut the fields along the dotted line, draw the ships in any order and start the game! Download the pattern template for the game with a sea background:

And the last option for the game is with a uniform background - a picture with shells and starfish. This image has calmer shades and is therefore more clearly visible. game elements. Download, print the fields and cut them into cards.

Templates with ships

I am posting for you forms with ready-made ship arrangements. The PDF file contains 10 sheets, each with two game cards. They are enough for 10 games between a pair of players.

Rules of the game

Two players are dealt game cards. You can take ready-made templates with ships from our website. On the left of each player is a field with his squadron, and on the right is an empty square of the enemy. It is on it that you will search for enemy ships, shooting at the target. Players “walk” in turns. the player alone “shoots”, naming the coordinates of the ship’s intended location. For example, A4. Player 2 looks to the left field, and if there is a single-deck ship at the coordinate, then he says “killed.” Player 1 marks this place on an empty square with the “Snowflake” icon. If only part of a multi-deck ship (two, three or four decks) is located at the coordinate, then player 2 says “wounded”. Player 1 marks the “Cross” (X) icon on the empty field and player 1 moves again until he misses. If player 1 calls a coordinate where there are no ships, then player 2 says “by.” Player 1 puts a point and the turn passes to the other participant in the battle.
