About
Drop little cosmic bodies into a glowing glass jar. When two of the same kind touch, they fuse into the next, bigger one: sparks become comets, comets become asteroids, and with a well-placed drop a chain reaction can turn a pile of moons into a sun.
Every drop is a small bet on physics. Pieces roll, bump and settle, so plan where they land and set up merges before the jar fills to the brim.
- Easy to learn: drag to aim, release to drop.
- 11 cosmic tiers to discover, from Spark to Nebula Heart.
- Chain merges for combo points; two Nebula Hearts set off a supernova.
- Quick runs of a few minutes, perfect for a short break.
- Your best score and tier ladder are saved on your device.
- No ads, no accounts, no tracking. Plays offline.
