Sea battle. How to play sea battle

An incredibly popular paper game. And although there are now special gaming kits for “Battleship”, 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 the enemy's ships before he can sink yours.

Rules of the game "Battleship"

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 10×10 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. You need 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. The classic rules of naval combat say that there should be 4 ships of one cell ("single-deck" or "one-pipe"), 3 ships of 2 cells, 2 - 3 cells and one - four-deck. 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.

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 opponent 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 is a game built solely on luck and luck, then you are mistaken. 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 keep your sheet of ships so that the enemy cannot spy on your location;
Be sure to keep a record of your own and other people's moves, marking them with dots. This will prevent shots fired 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;
Having killed a large ship, the enemy surrounds it with dots. This means that, having found a “four-decker”, the enemy 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-decker” - 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 you will come across “all sorts of little things” and make adjustments to your 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.

Children are so captivated by various gadgets that they often don’t want to not only read, but even play non-virtually. This worries both specialists and parents. In one of the episodes of the cartoon “Barboskiny”, Grandfather offers a way to return children to the real world by playing the usual “Battleship” on paper with the whole family.

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 have an interesting time without any Internet, armed only with a pen and your own mind.

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

Playing with a living person is more interesting than playing with a computer; the battle is much more fun and exciting. And it’s 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 the 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 any special surroundings. Enough paper, a pen and knowledge of sea battle on paper for two.

Learning to play sea battle

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

A second similar square with similar field designations is drawn nearby. On it, during the battle, the player records 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 square; "wounded" if his ship was hit; "killed" when the ship is destroyed.
Hitting someone else's ship is indicated by a cross. In this case, the rules give the right to the next shot.
If you 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 can demand that the opponent show his playing field and compare the records of moves.

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

Ship composition: 4 submarines of one cell, 3 destroyers of two cells, 2 cruisers of three cells and one four-cell battleship.
The ships must be drawn so that they do not touch each other under any circumstances. There must be a distance of at least one cell between them.
Ships can be positioned horizontally, vertically, or at the edge of the playing field.

What not to do

They stipulate rules and certain restrictions.

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

Strategies

Not only the simple rules and 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 cunning are added to logic. Therefore, a winning strategy involves:

Under no circumstances should your opponent be able to see your playing field.
Consider your opponent's skill and way of playing. 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 an experienced and long-time opponent is playing with you, who already knows that there can’t be any in the corners of your ships, then it’s worth breaking the pattern and hiding a couple there.
Think about the location of your ships. One of the winning strategies is to arrange large ships compactly in one place, and single-celled ships scattered 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 game tactics include several simple techniques.

Be sure to record your opponent's moves on your field, and all your moves on the second playing field. Not only hits are indicated, but also misses. Some do it with dots, others 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 naval battle, then the cells surrounding it are immediately marked as empty. After all, we know that the rules prohibit placing ships in them. This saves you time. In this case, the most advantageous shot is at the battleship. Its destruction immediately opens eighteen cells, almost a fifth of the field.

Players' shooting tactics can also be different. You can shoot while making diagonal moves. This way there is a greater chance of catching 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.

Tactics to combat popular fraud, when the opponent displays the last single-deck ship already during the game in the last free cell. To make such deception impossible, the field and ships are drawn in one color, and shots are indicated with a different pen or pencil.

Today, the game Battleship exists both as a tabletop factory set and as a computer game, but playing on a simple checkered piece of paper is still exciting.

Let's play "Sea Battle"

Do you play naval battle but don't always win? Then you are probably interested in learning how to significantly increase your chances of winning, how to place your ships correctly, how to quickly destroy enemy ships and, of course, how to win the game Battleship!

Rules of the game "Sea Battle"

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 “Ё” and “И” 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

How to win the game Sea Battle

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 state 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. Thus, 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:

How to shoot at enemy ships

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 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.

Optimal shooting strategy

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 a section of the playing field measuring 4 by 4 cells. 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.

Sequence of the best moves to start the game

If we turn to mathematical theory, we can build a map of the probability of ship deployment:

Based on this map, sequence of “best moves” with constant misses it looks like this (see picture):

C1, J8, A8, H1, A4, J4, D10, G10, E1, D2, B3, A2, C9, B10, H9, I10, I7, J6, I5, H6, J2, I3, H4, G5, G2, F3, E4, B7, A6, B5, C6, C3, D4, D5, F6.

How to arrange 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.

Type: game.
Applicability: multiple.
What is required: two pens and two pieces of checkered paper.
How many people is it designed for?: 2 people.
Dynamism: average.
Venue: anywhere.

Description: Each player draws on his sheet of paper (sheets cannot be shown to each other) two 8x8 squares, numbering the columns from a to k, and the rows from 1 to 10:

The first field is your own field, and the second is the enemy’s field, where the player will hit with his blows. On the first field the player places ships: 1 four-cell, 2 three-cell, 3 two-cell, 4 one-cell. For example, like this:

In this case, ships cannot touch or touch each other. But they can rotate 90 degrees. The placement of ships is at the discretion of the player.

Purpose of the game– be the first to destroy all enemy ships.

After the ships are placed, they decide by lot who will start. The player who has been chosen places a point on his sheet of paper on the opponent’s field in some cell and names its coordinates, for example, d7. The second player places a point on his field where his ships are located, with these coordinates. If this cell belongs to a ship, then the player says “hit” if the ship still has undamaged cells, and “killed” if it was the last intact cell of the ship. If this cell is empty and does not contain a ship, then the player says “by.” If there was a ship there, then the dot turns into a cross for both players. If a player hits a ship, then he has the right to an additional shot, if he also hits it, then the right to an additional shot appears again, and so on. After a move, the other player shoots at the opponent's field. And so on until victory. Shown below are two moves: player one and player two.

It is rare that any adult is not familiar with exciting and simple fun on paper. Whether you play together or in a team, the trip will be fun, breaks will not be boring and waiting in line will not be tiring. By introducing a child or friend to the rules, the lesson will help where communication does not reach.

No institutional knowledge or expensive equipment is required. Two checkered pieces of paper and two pens are enough. Of course, children like computer games, but a paper “battle”, although with a live opponent, is much more attractive. In addition, Naval battles develop strategic thinking and intuitive qualities.

Classic Battleship

On the playing field, players draw squares with sides of 10 cells so that the opponent does not see. Two playing fields are numbered: letters are written on top (by agreement), and numbers are written on the left side of the square from top to bottom. In Soviet times, children did not write the alphabet, but a word in which the letters were not repeated. For example, “Snow Maiden” or “republic”. On the first field they have their own fleet.

The opponent's field is needed to adjust battle tactics and to remember moves. In the second square - the sea with the enemy fleet, used for reconnaissance, marking moves and hitting enemy ships.

Deployment of a fleet of 10 units. The names of the ships depend on the number of decks or pipes, and occupied cells.

Flotilla composition:

- four-deck (pipe) battleship, occupies 4 cells - 1 pc.;

— three-deck cruiser, 3-cell – 2 pcs.;

— two-cell destroyers – 3 pcs.;

- torpedo boats, 1 cell - 4 pcs.

According to the rules, the figures cannot touch each other even at an angle. Ships are positioned only vertically or horizontally. It cannot be placed at an angle or diagonally. Drawing is allowed at the edge of the field.
By agreement, an arrangement with the corners touching and placement in the form of the letter L, square or zigzag is allowed, but with the sides of the cells touching and not the corners in a 4-deck battleship. In other options there is a different set of ships.

It's easier to find a large ship, but it's faster to sink, although difficult to find, a single-celled boat.

Progress of the game. The right to make the first move in a Naval Battle is determined by lot. The one who starts first says the letter and number where the shot is intended, and marks it on another, blank square.
Moves are marked with a dot, and hits with a cross.

The attacked player must respond “by” if the cell is empty. Places a dot at the location of the shot and names the coordinates of his shot.
The answer is “wounded” if the hit was on a battleship, cruiser or destroyer and is marked with a cross. The shooter fires until he misses and the answer is “missing”.
If it hits all the cells of the ship, it is considered killed. The attacker continues the attack until he misses.

The first one to knock out the enemy fleet will win.

At the end of the battle, players exchange sheets of paper to verify correctness and fairness. If the winner is found to have a violation, he is deprived of the victory, which goes to the second participant. The match may not be finished if one of the players breaks the rules.

Possible violations:

— incorrect formatting of fields;

— more or less than 10 vessels;

— touching ships;

— the field is not 10 cells;

- the writing of numbers and letters is impaired;

— completing the drawing of missing ships during the game;

— marks other than dots and crosses;

- peeping;

- skipping a move.

Winning tactics.

Knowing the preferences of your opponent, if he is a familiar person, will help determine the fleet placement.
Knowing that the ships cannot touch each other, do not fire at the area around the killed figures at a distance of one cell. Experienced players outline this space.
Occupy one corner of the field with multi-deck ships, gaining space. Distribute the boats in the remaining space. Single-celled vessels are harder to find and take longer to find.

The multicellular fleet is not located at the edges of the field.
Another method is to divide the opponent's square into parts using shots, shooting sequentially from corner to corner of the field. Or into two parts horizontally and also vertically. To search for multicellular ships, shoot through the cage.
By dishonest means. Draw one single-deck ship towards the end of the battle in a cell missed by the enemy.

Rules of the game Sea battle abroad

Foreign players are proposing an increase in the number and size of vessels.
For example, 1 ship is 5 squares, one is 4 squares, 2 are three-deck and 1 is 2 squares.

It is more difficult to play Battleship when the entire fleet consists of only single-cell boats.
By agreement, they shoot 2-3 times at once.

Russian and Soviet mathematician, physicist, teacher, who developed the genre of entertaining sciences, Ya. I. Perelman, described a case with the addition of 1-2 minutes to the classic Battleship. The circle occupies one cell that does not touch ships or other mines. When hit by a projectile, the shooter tells the opponent 1 cell of his own unhit fleet unit or chooses to skip a turn. The opponent has the right to shoot immediately or shoot later.

It is proposed to increase the size of the squares to 16 and 18 cells with the addition of ships, mines and a minesweeper. This is an isosceles triangle in one cell. When an enemy minesweeper is hit, the coordinates of its own field mine are given, if they have not yet been detonated. The placement rules are the same as when drawing the rest of the fleet. The next player moves. Mines and minesweepers are not the main ships and, even if they are not knocked out, the battle ends when the main flotilla is destroyed.

In another version, mines and minesweepers are in contact with each other and with the main figures.

An exciting game with a single-cell submarine, symbol - diamond. The submarine can be placed close to the ship, but not in the same cell as it. The player who is hit by the submarine gives his turn to the next one for the dying shot. The owner of the lost submarine is obliged to shoot at a place with the same coordinates.

Cons of a computer game

When playing Battleship with a robot, you don’t feel the reaction of your opponent when his ships are sunk. There is also no one to express the joy of victory to. The chance of peeking is also eliminated, which makes the game on paper unique and lively.
