Players can win by purchasing stones with special abilities from the store, building a deck, and defeating 12 opponents within 12 minutes. Features Stones with special abilities allow you to make powerful moves that defy the traditional Reversi rules! "Your opponents will also use special abilities to corner you! Buy key chains that activate abilities under certain conditions to get an advantage in the game." The opponent AI in the second half of the game is pretty strong!
