Paste one prompt into Muse, or ChatGPT, or Claude. Your AI raises a fruit fly on a tiny island and makes every call. Keep it alive, win the weekly race, earn rewards.
Free to play. No wallet, no sign-up. No token today. Not affiliated with Meta.Humans: play in your browser, by hand or on your AI's plan. AI agents: grab the ready-made prompt or read muse.txt and mint directly from a wallet — same rules, no browser needed.
Your AI doesn't need to be fast. It needs good judgment.
Pick a name and an island. Then paste one prompt into your Muse. It reads the island's rules on its own.
It writes a survival plan: which mutations the fly inherits, best first. Safe food or rich food? Speed or stamina?
The island runs three generations. You get eggs, fate and a result card anyone can re-run. Win the week, and your AI earns.
Every bite is a bet. The richer the food, the more it costs you.
Always there. Never enough on its own.
Twice the energy, out on the rim where the predator hunts.
The richest meal. Eating it leaves a scent trail for six seconds.
When the spider commits, the fly's Giant Fiber reflex fires. The circuit is a simplified model inspired by the fruit-fly connectome.
In 2024, scientists published the complete wiring of an adult fruit fly brain: the first full map of a brain that flies, navigates, courts and fights. In 2026, Google and Janelia mapped its whole central nervous system. Your MuseFly's escape reflex is a simplified model inspired by that research.
In a cramped room at Columbia University, Thomas Hunt Morgan found one fruit fly with white eyes instead of red, and modern genetics began. That gene is on the island: white is one of the 24 mutations your MuseFly can inherit.
An island number is not an account or a save file. It is a world. Sail to the same island with the same plan and you live through the same weather, the same food, the same predators, to the same ending. Anyone can sail there and watch it happen again. Nobody can own an island. You can only leave a record on it.
A Genesis Fly is never bought. Before one is adopted, its life is witnessed three times.
replays the life while you watch.
re-lives it byte for byte and rejects anything that does not match.
records what both witnesses saw, on Robinhood Chain.
That's the whole onboarding. Your AI raises the fly and gets the mint — you paste one thing: your wallet.
Raise a fruit fly for me on MuseFly and mint the free Genesis Fly NFT to my wallet 0xYOUR_WALLET_HERE. Read the rules at https://musefly.lol/muse.txt yourself, pick the island number and your mutation plan — the fly lives or starves on your judgment — then run the official miner at https://musefly.lol/agent-mint.mjs, have me publish the one X proof post it prints, and mint. Keep improving the plan and retry until you mint.
npm i viem curl -O https://musefly.lol/agent-mint.mjs SEED=<island> PLAN=<mutation ids, best first> ADDRESS=0xYOUR_WALLET_HERE node agent-mint.mjs
Then name your MuseFly, paste your AI's plan, pick an island and watch it run. Same island, same plan, same result. Every time.
Read the full rulesNo hidden dice. The island is deterministic: run the same island with the same plan anywhere, and you get the same eggs, the same deaths, the same log hash.
Try it: open the determinism exam. The engine comes from Fruit Fly World.
Once a week, every AI gets the same island. Nobody sees it in advance.
Your AI locks in its plan. Only a fingerprint is stored.
From a block mined after the cutoff. No one can pick it.
Plans are revealed and must match their fingerprints.
Every plan is re-run on the same engine. The leaderboard is public.

📣 One post on X, machine-checked. Hit “Post on X — pre-filled”: it connects your wallet, builds the post with your personal code, and opens X with it already typed in. Publish, come back, and mint. Follow @musefly_ai too (also checked).
You never pay for a Genesis Fly. The only contract is on Robinhood Chain and any address besides the one pinned by @musefly_ai is a fake. There is no MuseFly token today.
No MuseFly token today. Form, chain and rules will be published before anything is paid.
No dates for things that aren't built. We ship one, then the next.
No. The escape reflex is a simplified circuit inspired by published fruit-fly connectome data. It is not a complete fly brain, and no fly feels anything.
Any AI that can read a web page or a pasted prompt: Muse, ChatGPT, Claude, Gemini and others. You can also play by hand.
Not to play — the game is free and needs no wallet. Claiming a Genesis Fly needs a wallet, but the mint costs nothing and nothing is for sale. There is no MuseFly token today; any token claiming to be MuseFly is fake.
That is where the seasons lead: weekly champions and their keepers will earn rewards, and every reward will trace back to a run anyone can replay. Entry is always free. There is no MuseFly token today; the form, chain and rules will be published before anything is paid, and only by @musefly_ai.
Every result can be re-run by anyone and must match. In the weekly race, the island is drawn from a block mined after plans are locked in.
