Game board consists of adjacent squares some of which are “mined”. Objective of the game is to reveal all squares that do not contain mines.
The player reveals squares trying not to hit squares with “mines”. When a square with a “mine” is revealed, the player loses the game. In a single-player game, a first move will not lead to defeat. It is advisable for the player to start the game by revealing the four corner squares that are certainly safe.
It is possible to clear the game board if the player starts with revealing the four corner squares that are highlighted in yellow.
There’s an option of multiple revealing of squares: place marks in squares with hypothesized “bombs” and simultaneously press down on the right and left mouse buttons above the relevant digit. If the marks have been placed correctly, all mine-free cells shall be revealed.
