GENESIS — Seed the Cosmos

A free cosmic idle game. No download, no account. Works on phone and desktop, is installable, and plays offline.

You begin as a mote of dust. Matter gathers around you every second, and your mass grows with it. From there, the Great Chain rises through 34 forms—pebble to moon, moon to world, world to star, and onward into shapes that outrun astronomy entirely—each form multiplying your production. GENESIS is a game about patience, compounding, and the moment you let a world go.

The Basics

Matter flows in constantly; spend it on research—two lines of repeatable upgrades, plus one-of-a-kind Wonders that multiply everything. Hold the Gather button to build momentum for a burst of extra production; it fades gently when you let go. Watch the sky, too: comets streak by from time to time, and catching one grants a temporary blessing.

Seeding — The First Great Loop

Once you reach Moon form, you can seed your world with life. The run ends, the world joins your Garden, and you gain ✦ Genesis—a permanent currency spent on your Sun and Homeworld for bonuses that survive every reset.

Growth slows as size rises; when progress crawls, that wall is telling you a seed may be worth more than the grind. Deeper worlds gain more.

Collapse — The Second Great Loop

Reach the Golden Sun (tier 19), and a larger cycle opens: collapse the entire system into ⬢ Dark Matter, resetting your Garden and Sun in exchange for galaxy-scale upgrades that persist forever. Each galaxy compounds the last.

Everything Else

The Codex tracks achievements, every form you've reached, the classes of worlds you've seeded, and the traits you've bred. The leaderboard ranks Power and fastest milestone times.

Offline growth continues while you're away (with an upgradeable cap), and installing the game to your home screen makes it a full offline app while protecting your save from browser cleanup.

Fair Play & Fair Monetization

Everything in the game can be earned for free through play. Optional rewarded ads and Stardust conveniences exist for players who want to move faster—never as a wall.

The leaderboard validates every submission server-side against what is actually achievable, so the rankings mean something.
