This is a video game for one player. The purpose of the game is to clear the abstract minefield without detonating a mine.

The game plays the identification of the squares of the grid. If the square container containing the shaft is opened, the player loses the game. If no mine is found, the figure is displayed in the square instead of indicating how many neighboring squares to contain mines; If no mines are adjacent, the square becomes empty, and all neighboring squares will be recursively identified.
Simplicity for the game.
Infinite level.
