Sea battle best ship locations. How to play Naval Battle: 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. 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 voice 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 on which unsuccessful shots have already been fired are marked in yellow, the cells on which the shots ended in a hit are marked in red, and the cells that were not fired on 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 field border, 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.

"Sea Battle" is an exciting and simple game that does not require special tools and special knowledge. It can be played both on a computer and on paper, and only the second option was once used, since there was no other possibility. Not everyone knows how to play Sea Battle, because either there was no opportunity to learn, or there was no “teacher”. In any case, such knowledge can be useful. The rules of the game "Sea Battle" are simple, anyone can remember them, regardless of age and level of intelligence.

General

The game "Sea Battle" has long conquered many people. It is interesting, exciting, and most importantly - does not require any costs. To play with a person together, you will need two sheets of paper in a cage (preferably) and two pens (or 2 pencils).

"Battleship" is useful not only because it allows you to have a good time. The game also contributes to the development of strategic thinking and intuition. If you and the person know each other, you have the opportunity to use information about the enemy. For example, your assumptions about how he could place the ships so that they are hard to find, how you would place if you were in his place, can be confirmed and help win.

rules

Well, you can proceed to the main part. Now you will learn how to play Sea Battle:

1. First you need to draw two squares of 10x10 cells on a piece of paper (of course, it’s easier to draw on a sheet in a cell). Then, in both figures, put down the letters from A to K on the top row (from left to right, skipping E and Y), and to the left of the squares - the numbers from 1 to 10 (top to bottom).

2. On the left square you need to place:

  • 1 ship, consisting of 4 cells;
  • 2 ships, consisting of 3 cells;
  • 3 ships, consisting of 2 cells;
  • 4 ships, consisting of 1 cell.

Ships cannot touch each other either on the sides or on the corners. It is important that there is at least one free cell between them. Ships can touch the edges of the playing field, and they must be located only vertically and horizontally (not diagonally).

The right square must remain empty.

3. The goal of each player is to destroy enemy ships. The one who goes first (by agreement or by chance (using lots)), calls the coordinates (letter-number), looking at the right empty square. For example, E7. The opponent looks at his left drawing, where his ships are located, and answers:

a) past;
b) injured;
c) killed.

The first option means that the player has landed on an empty cell, that is, he has not landed anywhere. He marks this place in his right square so as not to choose it a second time (most often with a cross, but in any other convenient way), and meanwhile the turn passes to the second player.

The second option means that the player got into a multi-deck ship (occupying from 2 to 4 cells). Having marked the right place on his card, a person has the right to the next move until he misses. So, if after shouting E7 the answer “wounded” followed, the player can call either E6, or F7, or E8, or D7 to finish off the wounded ship (by the way, this is not necessary, you can temporarily leave it alone and look for others) . The second player again answers "by", "wounded" or "killed".

The third option means that the enemy ship has been destroyed. If this happened from the first move, then it was single-deck (consisting of one cell), which can be called a great success. If from the second (for example, after E7 the player said E6), then it is double-deck, etc. After knocking out the ship, as well as after being wounded, the player moves until he receives the answer "by".

4. The turn passes from one player to another in case of a miss and is delayed by one of the opponents in case of a successful hit. The person who first finds and destroys all enemy ships wins.

Other variations

Sometimes "Battleship" is on paper, and sometimes on a computer, as mentioned earlier. And if for the first option you need a real, live opponent, then in the latter case you can play with robots. True, firstly, it will not be so interesting (the reaction of the enemy when you sink his ship is priceless), and secondly, the opportunity to peep into the enemy fleet is absolutely excluded (we all understand that some people strive to cheat).

One way or another, it is not difficult to come up with other, more advanced versions of the game, it all depends on the imagination of the players and their desire / ability to experiment. It is important to immediately clarify all the rules, because if it is not clear to every person how to play the Sea Battle, the rules of which you came up with, nothing good will come of it, a quality game will not work.

For example, you can add more cells to the "battlefield" (not 10x10, but 20x20, for example), and then either leave the number of ships or increase them. You can complicate the task so much that all the ships that the enemy needs to find are single-deck. You can make mines, when hit on which the enemy misses one turn. There are a lot of options, the main thing is to know everything in moderation.

Conclusion

That's all, now you have got acquainted with the new game and you know its rules. The question "how to play Sea Battle" should be settled. From now on, you and your friends will have something to do during boring lessons / lectures or at work, if there is an opportunity to be close to each other and write on sheets of paper.

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.

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 voice 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.

Sea battle is a popular game with simple rules. When wondering how to win in a sea battle, a winning attitude and the right strategy will always help the player in this.

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 two-deck destroyers and 4 single-deck boats.

The fleet is located on the field so that the ships do not touch each other. Nearby, you need to draw the same field for the enemy to mark your shots. On a miss, the turn passes to the opponent. The one who sinks the opponent's fleet first wins.

You can agree with your opponent on the possibility of changing the shape of the ships, "bend" the ships. So the ships on the field will look like the details of the 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 courts;
  • the best option for firing at the enemy fleet.

Location of ships

There are several tactics for setting up your fleet. Whether the tactic will work or not will depend on the opponent's shooting tactics. In any case, the unsystematic placement of ships will not lead to a deliberately good result.

"Half Field"

The first tactic is that the battleship, cruisers and destroyers are located on one 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 take a lot of shots before he hears "Killed!".

"Diagonals"

Most players first start shooting the field along two diagonals - from corner to corner. If the opponent is of this type, the second tactic will come in handy. All ships are positioned in such a way that diagonal shots do not hit them.

This tactic is good because it can be used in conjunction with another placement tactic. A well-thought-out location of your fleet is half the success.

"Shores"

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

Such tactics may not justify itself, especially when the opponent guesses what the trick is. If the secret of the location of the ships is revealed, the opponent will sink the entire player's flotilla in the minimum number of moves.

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

By placing large ships in this way, there is a lot of free space for boats. There is no strategy for finding boats, and the opponent will shoot 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 strength and invulnerability of the player is precisely in single-deck boats - although they can be destroyed with one shot, for this you need to find them first. The more securely they are hidden, the more chances to win the game.

Destruction of the enemy

To destroy the opponent's flotilla, there are also several tactics. 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 through the diagonals, alternating the direction of fire for a change.

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

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

"Chess"

From the name it is clear how to "clear" the opponent's field. Tactics is good because it allows you to quickly find battleships, destroyers and cruisers. However, the search for boats will have to sweat.

"Locator"

Tactics is a bit similar to Chess, however, with its 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 shoot them diagonally. As a result, the field will be divided by a white cross. Given the number of ships that have already been sunk, it will not be difficult to find the rest. In the picture, the player has discovered six ships thanks to the Locator tactic.

"Crow's feet"

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

So, to find a battleship, you can use the "crow's feet" tactic. To do this, mentally divide the field into squares measuring 4 by 4 cells and make four volleys in each square.

In the first upper square, the player fires a volley at A3, B4, B2, G1. Then it remains to repeat the pattern in other squares. The battleship will be found in a maximum of 24 shots.

After the battleship is found and sunk, you can move on 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, do the same with the rest of the minifields. The eleventh shot is guaranteed to knock out the cruiser.

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

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

  • The rules of "Naval battle" do not prescribe to finish the ship after the first "Wounded!". However, it is better to bring the matter to a victorious “Killed!”, Because in this way the player can figure out which cells can not be shot at. After all, ships cannot stand close to each other.
  • When shelling the enemy's field, you do not need to stagnate in one place. Shots should cover as large an area as possible. Keeping the tactics they like in mind, the player can "walk" around the field, instead of continuing to fire at an unsuccessful area.
  • If the opponent uses some kind of tactic, and does not randomly fire at random cells, you need to turn on your 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 tactics of placement and shelling, using the experience gained to improve his own strategy.

You can use online services to practice your skills in playing Sea Battle and check your tactics. The advantages of gaming sites are high speed and low resource consumption. And having developed and improved his strategy, the player will be able to show off his knowledge in the 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. It is for this reason that Sea Battle remains a fun way to pass the time.

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 is that two players take turns calling 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 the 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 more 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 it is not recommended to draw them there.
  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.
