Buscaminas app for iPhone and iPad

Buscaminas (Minesweeper) is a single-player puzzle game in which the objective is to clear a rectangular board containing hidden "mines" without detonating any of them, with help from clues about number of neighboring mines in each field. The game is played by revealing squares of the grid by clicking or otherwise indicating each square. If a square containing a mine is revealed, the player loses the game. If no mine is revealed, a digit is instead displayed in the square, indicating how many adjacent squares contain mines; if no mines are adjacent, the square becomes blank. The player uses this information to deduce the contents of other squares, and may either safely reveal each square or mark the square as containing a mine.
