Minesweeper - computer puzzle game.
The player opens the cells, trying not to open them with a mine. Opening the camera with the mine, he loses. Mines are set after the first move, so it’s impossible to lose on the first move. A flat or three-dimensional playing field is divided into adjacent cells, some of which are “mined”; the number of "mined" cells is known. The goal of the game is to open all the cells that do not contain mines.
