Pop ocean fizz bubbles rising from coral vents in vivid coloured streams. Matching colour clusters triggers cascade bonuses. Rare pressure bubbles appear in the fizz stream and score triple when popped as part of a five-bubble chain. Special coral events release bubble storms from every vent simultaneously.

Pop arctic frost bubbles forming in icy streams before they freeze solid and become impassable. Chain pops score cascade bonuses. Rare crystal ice bubbles appear once per arctic wave and score triple when popped as part of any chain. A blizzard event every fifth level freezes all current bubbles for five seconds.

Build a tower into the sky by tapping to drop each platform at the perfect moment onto the stack below. Overhang is sliced off, narrowing the next platform. A perfect drop restores the last sliver. The platforms swing faster and from alternating sides as the tower climbs. Reach one hundred floors for sky builder glory.
