Cosmerge

Merge planets into stars and black holes. Duel a friend in real time, climb the world leaderboard, and claim your unique player tag. Can you build the cosmos?

Drop planets. Merge them. Build the cosmos — and beat the world doing it.

Cosmerge is a relaxing yet deep merge-puzzle game set in space. Drop planets into the cosmic container and merge matching pairs to evolve them — from tiny stardust all the way to stars, supernovas, and black holes. One wrong drop and the cosmos overflows; how far can you evolve?

EVOLVE THE COSMOS • 11 evolution tiers, each with its own hand-tuned look — living stars, supernovas, and a black hole that bends light • Merge two black holes to trigger a Cosmic Reset and clear the board in style • Special planets — Meteors and Wilds — shake up every run
