About Merge Cosmos
Merge stardust into moons, stars, black holes and galaxies. A relaxing idle merge game with 36 cosmic wonders to discover.
Tap the Forge to create stardust, then drag identical objects together to merge them into the next tier, from pebbles and moons to pulsars, quasars and whole galaxies. Every object produces Energy, even while you are away, which you spend on upgrades. Reach a Blue Giant to go Supernova for Stellar Shards that power a permanent skill tree.
