Cosmo Merge

Cosmo Merge is a drop-and-merge puzzle with a cosmic ladder to climb. You drop small celestial bodies into a glass jar, and whenever two identical ones touch they combine into the next size up: stardust becomes a comet, then a moon, planets, a blazing Sun and finally a Galaxy. Where you drop each piece matters, because the jar fills faster than you expect.

Keep the stack below the red danger line; let it sit above the line for two seconds and the round is over. Chaining merges earns combos, and when the jar gets crowded the Shake, Pop and Swap boosters buy you some room. There is an endless mode for a long session and star-rated missions for shorter goals, plus eight skins and an album to fill.
