Tap a domino to tip it the way its arrow points. It knocks the next domino, which falls the way its own arrow points, and so on. Every fallen domino drops into the 7-slot tray, and three of one color clear. Clear the board to win; if the tray overflows, the level is lost. Tap in the middle of a chain to split it: the dominoes behind your tap stay standing. Levels have no timer, and the game plays offline.
Yes. All 5000 levels are checked by the game's own solver. If you get stuck, use Undo, a Hint or +1 Slot, or restart the level.
Ice dominoes need two hits. Mystery dominoes hide their color until they fall. Spinners turn a quarter turn with every tap. Bombs knock all four neighbours. Stopper walls end a chain.
