Russian Minesweeper — multiplayer version of the game "Minesweeper"

Hello, dear readers. I sincerely hope that among the readers of Habra there are fans of such wonderful games as "Super".

If remember correctly, the first time this game appeared on the operating system Windows 3.1 in the distant 1994 year. At the time this game was positioned as a means for learning to use a computer mouse and, in General, the graphical interface of the OS. She looked like this:

the principle of the game according to Wikipedia

Flat or three-dimensional game field is divided into adjacent cells (squares, hexagons, cubes, etc.), some of which are "mined"; the number of mined cells is known. The aim of the game is to uncover all cells that are not containing mines.
The player opens the cell, trying not to open the box with mine. Opening the cell with a mine, he loses. The mines are placed after the first move, so to lose at the first move is impossible. If by open cell mines not, it appears the number of cells adjacent to the newly opened, "bomb" (in each version of the game the neighborhood is defined differently); using these numbers, the player tries to calculate the location of mines, but sometimes even in the middle and at the end of the game some cells still have to open at random. If adjacent cells also there are no mines, it opens some "not contaminated" area to the cells that have numbers. "Mined" cell, the player may mark, so you don't accidentally open them. Open all "not mined" cell, the player wins.

However, time goes by, the popularity of minesweeper is falling, and I want to make a new life and colors in this game. So was born the multiplayer version of the game, named as "Russian Minesweeper", which is a browser-based online game. Interested please under cat.

game Features

Of course, a certain number of players were able to play this game, the rules will have any way to modernize and even transform. However, the main rule — the significant principle left as in the original.br>
Thus, in fact, was developed a set of rules to allow multiple players to simultaneously play on the same field.

The basic rules are as follows:

the Aim of the game is to mark all mines with flags. the

each player has their (local) flags.
players Have the same (global) field with mines.
Players take turns (however, currently, we are developing a "parallel" mode).
If the player clicks on a mine, he loses and his opponent wins, respectively.
the Time on the player is limited (~25 sec.) — Ontario regional Council must as soon as possible.
If a player will miss the turn three times in succession, he loses and his opponent wins, respectively.
If a player misses six moves during the game, he loses and his opponent wins, respectively.
a Draw is impossible. One of the players in any case, set the flags correctly faster than the other.

the First move goes to a random player. the

the Player may surrender at any point in the game.

Also developed a number of characteristics of a minefield for the game:

Undermining at the opening of the first cell in the beginning of the game impossible.

the Mines are uniformly distributed on the playing field. the

Properties of "emptiness" to be opened after the first click:
1. Size from A to B, empty cells (0 mines around).
Thus, in the current configuration, the first click opens the "void" from 3 12 "zero" cells and the size field 32x20.

Sorry for the huge number of lists, however, can not fail to mention that the game in addition has the following functionality:

the
- chord — open more than one cell per turn. This is possible in case of a click (LMB) on the figure in the cell on the playing field, and the number of flags around the four adjacent cells equals the required number.
- Help the opponent — middle mouse button or [click the nick of the opponent from the top+click on the desired cell]. Appears green:
- Chat between players in real-time.
- in-game Nickname.
- Sound in the game.

Interesting facts

the
- With 119tries minefield has been passed through.
- Box size 32x20 is optimal for the game (empirical observation).
- From 3 12 "zero" cells it is best to open when first clicked (theempirical observation).
And attach a map of clicks from Yandex.Metrics, it is possible to make a number of interesting conclusions. For example, it is obvious that the main area of the "battle" is the center of the field, and chat popular.

the
