About Cosmo Merge

You drop celestial objects into a cosmic arena and merge matching pairs to create bigger bodies in Cosmo Merge. Start with asteroids and combine two of the same type to evolve them—asteroids become comets, comets turn into moons, and you keep climbing through planets, gas giants, and stars toward the ultimate prize: a black hole. The challenge is managing your space; as objects pile up, you need to plan each drop carefully to keep matching pairs accessible.

What keeps you hooked is the physics and the spectacle. Objects tumble and settle naturally, so every drop can trigger a chain of merges if you position things right. Watch solar flares ignite, see the black hole's accretion disk spin, and trigger explosive supernovas as you progress. The hand-drawn animations and satisfying merge mechanics make each session on Poki Games feel both calming and quietly competitive as you chase a new high score.
