Every coin gets a game.
Launch a coin on pump.fun. An AI builds its game, then keeps adding to it as the coin trades.
This is the idea, already running: a coin whose game an AI keeps building, one build a night. It is our own project, launched before this site, with a home of its own at bearproof.app.
Being built right now
Nothing has been built yet. The first launch will show up here.
How it works
Launch a coin
Give it a name, a ticker and a picture. Your wallet creates it on pump.fun, where it trades like any other coin there.
It gets a game
Pick a ready-made game and play in seconds, describe one and have an AI build it, or bring a game you already made.
Trading funds the next update
Every trade pays a small creator fee. Part of it fills the game's budget. Players suggest what comes next, and each time the budget is full, holders vote on what the AI builds.
One fee, followed from a trade to an update
The arcade
Open a game to play it. A game with a coin shows its dev log, what players have asked for and what holders are voting on.

Where the fees go
pump.fun pays a creator fee on every trade of a coin. For coins launched here, where that fee goes is set on chain and locked when the coin is created.
- Game budgetPays for the AI that builds that coin's next update. It can only be spent on that coin's game.
- PlatformRuns the service: servers, testing, moderation and the people behind it.
No fees have been collected yet, so there are no totals to show. See how it is enforced on chain
Three ways to launch
Quick template
Free
- Pick one of 3 ready-made games: survivors, hill racing, platformer
- Playable the moment you upload a picture, with your coin in the game
- Updates build on the game you picked
- You do not describe your own game
- Up to 3 launches per wallet per day
Custom game
From 0.2 SOL
- Describe the game in your own words and watch it get built
- Choose the AI that builds it: Claude, ChatGPT, Gemini, Grok, Kimi, DeepSeek, Qwen, GLM. The price depends on the model
- Any single-player 2D game that runs in a browser, with keyboard and touch
- 2 revisions included before you launch
- No 3D, no multiplayer, nothing that needs a server
- If the game cannot be made to pass its tests, a refund request is opened for you
Your own game
Free
- Already built a game? Upload it as one HTML file and launch its coin here
- It is scanned and tested like every game here, then hosted in a sealed frame
- Ship new versions whenever you like; players leave suggestions on its page
- No AI builds for it, and there is no game budget
- No network, links or wallet prompts inside the game
Whichever way, pump.fun's own creation cost and the network fee are paid by your wallet when the coin is created.
Questions
Can I lose money?
Yes. Coins launched here trade on pump.fun, and most coins like these lose most or all of their value, often quickly. A game does not make a coin worth anything, and nothing on this site is a reason to expect a profit.
Only use money you can afford to lose completely. Playing the games is free and never needs a wallet.
Who controls the fees?
When a coin is created here, the creator's wallet signs pump.fun's fee-sharing instructions. They send the coin's creator fees 100% to the platform's wallet, and pump.fun then locks that. The creator cannot change it afterwards and neither can we.
One thing can: pump.fun's own admin authority and its community-takeover process. If a coin's split ever stops matching, we mark the coin as unverified and its game stops getting updates. We re-check every coin regularly.
What happens if a coin stops trading?
Updates stop, because trading fees are what pay for them. The game stays online and playable.
What can the AI not build?
3D games, multiplayer, anything that needs a server or an account, anything built around betting or chance-based rewards, and games that use someone else's characters or brands. Each update is also capped in cost, so updates are small: a new enemy, a weapon, a boss, a map.
It builds single-player 2D games that run in a browser with keyboard and touch. If you ask for something outside that, you are told why before you pay.
Do I need a wallet to play?
No. Browsing and playing never ask for a wallet. You need one to launch a coin or to vote on an update. Games run in a sealed frame on a separate address and cannot see or reach a wallet.
Are high scores worth anything?
No. Scores are sent by your browser and can be faked, so they are for fun only. Nothing here pays prizes, and there are no raffles, jackpots or rewards tied to playing.
