Naval battle play print. Rules of the game sea battle on paper with a strategy. Optimal ship placement

You can not draw these fields, but immediately download the finished 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 superfluous graphics, which means that less ink will be used during printing. At the bottom of each card is a graphical clue to the number of ships. Let me remind you that according to the rules of the game, each participant in the battle should initially have 1 four-deck ship (4 cells circled), 2 three-deck, 3 two-deck and 4 one-deck. 1 deck = 1 circled square. When building ships, they should not touch at the corners or sides.

Not everyone wants boring white naval combat cards. Therefore, I bring to your attention a template for a naval battle with a thematic background. Cut the boards along the dotted line, draw the ships in random order and start the game! Download a scheme template for a game with a sea background:

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

Ship patterns

I am laying out for you forms with ready-made arrangements of ships. IN PDF file- 10 sheets, each of which has two game cards. They are enough for 10 games between a pair of players.

Rules of the game

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

A couple of days ago I was surprised to learn that some of my friends do not know how to play sea battle. Those. Of course, they know the rules, but they play somehow haphazardly and as a result often lose. In this post, I will try to outline the main ideas that will help you level up 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 10 by 10 square field, and the ships cannot touch either 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 "Yo" and "Y" are skipped).

An enemy field of the same size is drawn nearby. In case of 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;

Optimal Strategy

There is always an element of randomness in the game of naval combat, but it can be minimized. Before proceeding directly to the search for the optimal strategy, it is necessary to state one obvious thing: the probability of hitting an enemy ship is higher, the fewer unchecked cells are left on its field, similarly, the probability of hitting your ships is the lower, the more unchecked cells are left on your field. That. 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 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 are marked in yellow, on which unsuccessful shots have already been fired, cells on which shots ended in a hit are marked in red, and cells on which no shooting was carried out are marked in green, but it can be guaranteed that the ships there are no ships in them (ships cannot be there, because according to the rules of the game, ships cannot touch each other).

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: you must first 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 immediately receive information about 14 guaranteed free cells, and by destroying a cruiser, only about 12.

That. 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.

To begin with, let's consider a 4 by 4 cell area of ​​the playing field. If there is an enemy battleship in the area under consideration, then it is guaranteed to be knocked out in no more than 4 shots. To do this, you need to shoot in such a way that there is exactly one checked cell on each horizontal and vertical. below are all options for such shooting (excluding reflections and turns).

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

After the enemy battleship is destroyed, it is necessary to start searching 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 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 (green indicates the fields that you have already fired at 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 strategy for placing ships is in some sense the reverse of the optimal strategy for firing. 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 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:

Similarly, a cruiser standing in a corner opens only 6 fields instead of 12. 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 left by the time you catch the boats, the harder it will be for the enemy to win.

Below are three ways to place capital ships that leave a lot of room for boats (marked in blue):

Each of the above arrangements leaves exactly 60 free cells for boats, which means that the probability of accidentally hitting a boat is 0.066. For comparison, it is 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 want to say that you should not spend too much time playing sea battle. I especially want to warn you against playing in lectures. When I was sitting in Wabi Sabi and playing sea battle with my girlfriend, a waitress walked by and said that she plays quite well, because. I practiced a lot in pairs. Who knows what she would have worked for if she had listened to lectures at one time?

P.S. The comments absolutely correctly indicate that there were already similar publications on Habré, it would be wrong not to put links to them.

Content

A simple and exciting game that has been known since childhood is sea battle. The rules of the game are not very complicated, anyone can remember them. Sea battles are liked by adults and children, you can play it anywhere.

Rules of the game Sea battle

The essence of entertainment lies in the fact that two players take turns naming certain coordinates on the opponent's map, which they do not know. The named point must hit the ship or part of it. The task of each player is to sink all enemy ships as soon as possible. There are several options for such a game today:

1. On paper. This method is considered a classic entertainment option. It allows you to play anywhere. A checkered notebook or one leaf (not even lined) is suitable for battles.
2. Desktop. The first version of such entertainment appeared more than 80 years ago. The board game sea battle was voluminous and colorful. After a while, many variations appeared with different numbers of ships, other sizes of fields.
3. On the computer. Modern gadgets can easily be turned into a battlefield for ships by downloading and installing the right application. There are options to play online. 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 sea battle, you need to understand the basic concepts. You need to start by drawing your playing field. It is a coordinate plane, a square 10 by 10. Each of its sides has its own definitions: the horizontal is numbered from top to bottom, the vertical - with letter designations. The letters of the Russian alphabet are used from "A" to "K" or from "A to "I", if "Yo" and "Y" are omitted. Often, instead of letter designations, the words "Snegurochka" or "Republic" are used. They consist of ten letters, which corresponds to 10 squares on the playing field.

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

Number and placement 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, "two-deck" or "two-pipe"). On the playing field are:

• 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 cell.

In the classic game, it is necessary to draw ships on the playing field according to the rules. For example, all court sides or corners cannot touch each other. There are variants of the game when the ships are placed in the letter "G", 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 a larger number of ships, a different form of the field is used, 15 by 15 in size. It is necessary to decide on the choice of the game in advance.

Game progress

Playing sea battle on paper is necessary in accordance with certain rules. The instruction defines the conditions and sequence of moves:

1. Initially, who will go first is chosen. To do this, the 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". According to the named coordinates, the ship is located, then “wounded” - if it was hit, “killed” - when completely destroyed.
4. A cross indicates a hit on an enemy ship. With such a successful shot, according to the rules, the player moves a second time. The right to move is transferred to the second player if the blow fell on an empty field.
5. The winner is the one who first sinks all the ships of his opponent.
6. At the end of the game, the opponents may require each other's playing fields to check. The loser will be the one whose fields are filled incorrectly. Victory goes to the one who waged a fair fight.

There are certain restrictions in the game. The game may be ended earlier if there is a violation of the rules. The following are considered gross violations:

1. Incorrectly drawn field - the number of vessels exceeds the required one, the dimensions of the sides or the coordinate system are incorrect.
2. One of the players spied on the location of the ships from the other.
3. Skipping a turn due to inattention.

Win strategy

A simple battle is not built solely on luck. To achieve victory, there is a strategy and tactics of playing a sea battle. It is as follows:

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

Children are so passionate about various gadgets that they often do not want to not only read, but even play not in the virtual. This worries both professionals and parents. In one of the series of the cartoon "Barboskiny" Grandfather just offers a way to return children to the real world by playing the whole family in the usual "Battleship" 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 it is possible to have an interesting time without any Internet, armed only with a pen and your own mind.

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

Playing with a live person is more interesting than with a computer, the battle is much more fun and exciting. Yes, and 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 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 some special entourage. Enough paper, pen and know the rules of the game sea battle on paper for two.

Learning to play sea battle

The rules of the game on paper in a sea battle for two people are quite simple. On paper, each player must draw a square of 10x10 cells, which are denoted on one side by letters from A to K (without Y and Y), on the other by numbers from 1 to 10. In this field you need to arrange your ships.

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

• When making a “shot”, the player names the coordinates of the target, for example, B8.
• The opponent answers "by" if there is nothing in the cell; "wounded" if his ship was hit; "killed" when a 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 first destroys all enemy ships.
• At the end of the game, the participant may require the opponent to present 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.

1. Composition of ships: 4 submarines of one cell, 3 destroyers, consisting of two cells, 2 cruisers of three cells and one four-cell battleship.
2. It is necessary to draw ships in such a way that they in no case touch each other. There must be a distance of at least one cell between them.
3. You can place ships horizontally, vertically, and at the edge of the playing field.

What Not to Do

Set rules and certain restrictions.

1. You cannot change the composition of ships.
2. Some rules say that one ship can only have a linear shape, in some cases the shape of the letter L is allowed. This point must be specified in advance. But in all variants it is impossible to draw and place the ships diagonally.
3. You cannot change the field size.
4. You can not distort the coordinates and hide the hit.

Strategies

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

• Under no circumstances should your opponent be able to see your playing field.
• Consider the skill and the way your opponent plays. For example, if your opponent is a novice player, then you should not place your ships in the corners of the field. Inexperienced players often start with them, especially with the move A1. If you have an experienced and longtime opponent playing with you, who already knows that there can’t be in the corners of your ships, then it’s worth breaking the pattern and hiding a couple there.
• Consider the location of your ships. One of the winning strategies is the location of large ships compactly in one place, and scattered single-celled ones away from each other. Then the player, having quickly found large ships, will spend a lot of time searching for small submarines. This will give you time and a chance to recoup.

Winning tactics

The correct tactics of the game include a few simple tricks.

Be sure 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 does it with dots, someone with crosses. This will avoid repeated shelling of empty squares and conflicts, in case of any errors.

If the opponent's ship is "killed" in a sea battle, then we mark the cells surrounding it 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 immediately opens eighteen cells, almost a fifth of the field.

The shooting tactics of the players can also be different. You can shoot by making diagonal moves. So there are more chances to hook large ships. You can, in search of a profitable battleship, shoot through three cells to the fourth. After the first hits, you determine the choice of moves based on what begins to peep through on the enemy playing field.

A tactic to combat popular fraud, when the opponent sets up the last single-deck ship already in the process of playing in the last free cell. To make such deception impossible, the field and the ships are drawn in one color, and the shots are marked with a different pen or pencil.

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