Choose your rules. Every mode starts with the same simple move and builds toward a different kind of chain reaction.
You can change board size and difficulty from Settings once the game starts.
Drag dominos onto the board.
Tap a domino to rotate it.
Match 3+ same tiles to merge them into the next value.
Chain reactions earn bonus points!
Red 6s vanish when matched.
Chaos: matching 4+ tiles collapses the board downward. Matching 4+ sixes instead destroys and scores every tile in the ring around them — nothing falls after that blast.
Ultimate Chaos: same 4+ thresholds and six explosions, but every collapse throws the board up, down, left or right at random — and exploding sixes trigger a collapse too.
Game ends when no moves remain.
