Chain Rules is a tile-matching puzzle where the rules change every round. Tap groups of three or more matching tiles to clear them and set off chain reactions. Clear enough tiles to finish the round, then choose one of three abilities: a rule that reshapes scoring for the next few rounds, or a tool you can fire whenever you need it. Between rounds the board fights back with new physics: gravity that pulls sideways or to the center, frozen tiles, fog and conveyor rows. Survive ten rounds to win, then keep going for a higher score. - DAILY: one new board each day, the same for every player. One shot, then share your run. - WEEKLY ASCENT: the same board all week. Lock in permanent rules at rounds 3, 6 and 9 and beat your best. - CLASSIC: Easy, Normal and Hard. - ZEN: no game over, just chains. Plays offline. No account. Optional ads only when you choose to watch one for an extra shuffle.
