Cosmo Crush: Planet Merge

New: chase 65 badges, bank Stardust, and unleash the Nova Bomb when the board gets tight. How far can you merge before the black hole?

Drop. Merge. Explode.

Cosmo Crush is a physics merge puzzler set in deep space. Drop moons into the chamber, merge two of a kind, and watch them collapse into something bigger: Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter, and finally the Sun. Keep going and you'll trigger a Supernova. Keep going further and you'll create a Black Hole.

Simple to start. Genuinely hard to master.

12 COSMIC TIERS Every merge climbs the chain, from a humble Moon all the way to a Black Hole. The higher you climb, the more room you free up — and the more the board fights back.

REAL PHYSICS, REAL TENSION Planets roll, settle, and stack the way real objects would. Every drop changes the shape of the board. There's no undo, and gravity has opinions.

CHAIN YOUR COMBOS Merges that cascade multiply your score. Set up a chain reaction and watch a single well-placed moon collapse half the board.

POWERUPS FOR WHEN IT GETS TIGHT Earn Stardust as you play and spend it on four powerups: • Planet Swap — trade the planet you're holding • Planet Skip — skip a bad draw • Shrink Ray — halve a planet that's in the way • Nova Bomb — blow up the board and restack everything that survives

65 BADGES TO UNLOCK From your first merge to feats most players never manage. Each one pays out Stardust.
