This is a minesweeper game with hexagonal tiles. The purpose of this game is to uncover all the tiles without uncovering a mine. After opening a tile, a number will be shown telling you the number of mines adjacent to this tile, and you can use this information to deduce whether a tile is free of mines or not.
This game is played by mouse only.
