Nebula Merge

Drop celestial bodies into a cosmic well. Matching tiers merge, the pile rises, and one slip past the danger line ends the run. Fuse Stardust into Asteroids, Moons, Planets, Stars, and beyond — all the way to an Eternal Nebula. Comets promote whatever they touch. Void Shards erase a body for score. Earn Stardust, buy permanent upgrades, collect every body, and chase daily, weekly, and monthly challenges. Prestige to keep a forever Stardust bonus. Climb the Game Center leaderboard — beat the record and a Record Breaker jackpot drops. Cosmic Pass removes ads and always doubles end-of-run Stardust. Stardust packs are optional. Portrait. Offline. No account required.
