About Cosmo Merge
Cosmo Merge is a relaxing yet addictive space-themed merge puzzle game. Drop celestial bodies into the cosmos and merge identical ones to evolve them into larger, more powerful objects, starting from tiny Asteroids all the way up to the legendary Black Hole! Two Asteroids become a Comet. Two Comets form a Moon. Keep merging planets, gas giants, and stars to climb the cosmic ladder. How high can you score before space runs out? With hand-crafted animated visuals, blazing solar flares, a spinning Black Hole accretion disk, explosive Supernovas and satisfying physics-based gameplay, Cosmo Merge is easy to learn and impossible to put down.
It leans fully into puzzle, so if that's your thing, it delivers. Pick it up for a short break or settle in for a while — it runs well on phone, tablet, and desktop alike.
If you want to do well, keep this in mind: When you are stuck, undo the last move and look at the board again instead of forcing a fix. Slow down on the first level — the early stages teach mechanics you will need at the end.
Ready when you are: Cosmo Merge runs right here on Glaze Games, free and unblocked, straight in your browser with nothing to install.
