Start with a mote of stardust and merge your way to planets, stars, galaxies — and an entire universe. A calm, cosmic idle game you can play in bursts.
Cosmos Merge is a serene idle-merge game about building everything — from a single grain of stardust to the entire observable universe.
Drag two alike together and watch them become something greater: dust becomes pebbles, pebbles become worlds, worlds ignite into stars, stars gather into galaxies. Each step up the cosmic ladder is a small, satisfying moment of creation, set to an ambient soundscape and a quiet field of stars.
There's no pressure and no timers — just the calm rhythm of merging, the glow of each new creation, and the awe of watching a universe take shape in your hands.
FEATURES
• Merge across five cosmic scales — dust, worlds, stars, galaxies, and the universe itself
• Ascension moments: the objects you built snap into orbit around each new creation
• Big Bang prestige: complete the universe and begin again with permanent boosts
• A Codex of real astronomy — tap any object to learn the science behind it
• Your Cosmos: a permanent trophy gallery of everything you've built
• Idle progress: the Cosmic Forge keeps working while you're away
• Meaningful upgrades — never pay-to-win
• Calm by design: colorblind-safe tokens, reduce-motion support, independent sound and music controls
Optional rewarded boosts and a one-time Remove Ads — no forced interstitials, no energy timers, no walls. From dust to the cosmos, one merge at a time.
