Tap a group of two or more bubbles of the same color and the whole group pops.
Bubbles above fall down to fill the gaps, and empty columns slide over to close up.
Clear the whole board to finish the level. If only single bubbles are left, they pop on their own in a sparkly finish, so you can never get stuck.
Rainbow bubbles match every color at once.
Boom bubbles (with the spark badge) pop everything touching the group when their group pops.
Ice bubbles do not pop until two pops next to them melt the ice away.
Zap bubbles (with the lightning badge) zap their whole row: pop one with its group and every bubble in its row pops too. Zaps can set off Booms — and other Zaps!
Twin bubbles are two colors at once. A Twin pops with a group of either of its colors, and can connect two groups of the same color into one big group.
Finish a level to unlock the next one. Finished levels can be replayed any time.
Each level gives you a tap budget. Run out of taps and you can simply try the level again.
Finish in fewer taps to earn more stars.
Every color also has its own symbol, so you can match by shape too:
