This free game is a minesweeper game with 5 different modes: tri mode, quad mode, hex mode, oct mode and dodec mode. While the classic minesweeper has only one mode: oct mode.
The object of this game is to open all the blocks without opening a mine. When you open a block without a mine, a number will be shown indicating the number of mines adjacent to it. You can then use this information to find out blocks without mines and then open them.
