The point of this game is to match a line or diagonal of three or more gems, using columns of three pieces falling into the playing field and to get as much points as possible. At the end of each level, a column of bomb blocks appear and whatever color gem it touches, all of them disappear. This special column also appears when you press the bomb button that is available after the Power-up Bar is filled up. The background changes between levels and the columns move gradually faster. If you lose the game the playing field will be filled in with exploding bombs.
