MineSweeper

Minesweeper is a deceptively simple test of memory and reasoning, and one of the most popular games of all time. The goal: find the empty squares and avoid the mines. The faster you clear the board, the better your score. Minesweeper has three levels to choose from, each progressively more difficult. The rules in Minesweeper are simple:
Uncover a mine, and the game ends. Uncover an empty square, and you keep playing.
Uncover a number, and it tells you how many mines lay hidden in the eight surrounding squares, the information you use to deduce which nearby squares are safe to touch.
If you suspect a square conceals a mine, then long touch it for 2 seconds, thihis puts a flag on the square.
