Each level is 60 seconds. Hit the target score before the clock runs dry. Three stars for a double-target run. Coins carry over to the shop.
Boosters are consumable. Buy them here, then tap one during a level — beam, bomb and hammer ask you to pick a crystal. Coins come from finishing runs: gold stars pay the most.
The clock is stopped.
Nice run.
1. Swap two neighbouring crystals — tap one, then the other, or swipe.
2. Line up three or more of the same shape to clear them.
3. Chains multiply your score: every extra cascade adds a bigger bonus.
4. Beat the target score in 60 seconds to clear the level.
5. Clear levels to earn coins, then spend them on boosters in the shop.
