Cosmica: Idle Universe

Build a universe that runs itself.

Cosmica is an idle game about growing the cosmos from a single backyard telescope to engines that bend reality. Tap for stardust, buy generators, and watch your numbers climb into the undecillions, even while you're away.

AUTOMATION
- Auto-buy: flip the gear on a generator and Cosmica keeps buying it for you. It works on your first generators from the start, and the Autonomy branch of the Cosmic Tree extends it to the rest.
- Auto Big Bang: pick a shard target and prestige happens on its own. Or tell it to hold until you reach Absolute.
- Auto-spend: banked Cosmic Shards flow into your cheapest Cosmic Tree upgrade after every Big Bang.
- Try automation free for 4 hours, or unlock it for good.

BIG BANG, THEN GO BIGGER
- Your first Big Bang comes early. Reset your generators for Cosmic Shards, and each shard boosts your earnings permanently.
- Spend shards on the Cosmic Tree for permanent upgrades, or hold them for an even bigger boost. The choice is yours every run.
- Climb 12 tiers in a single run, from Stargazer to Absolute.
- Reach Absolute and unlock True Cosmos: collapse the whole universe for Reality Fragments, a permanent multiplier that carries across every cosmos.
- Build Cosmic Wonders, endgame projects that change how the game plays.
- A new Weekly Cosmic Challenge every Monday. Each one completed adds a permanent Challenge Star.
