# Leo · iamleo.xyz > Leo ($LEO) is one of twelve zodiac token games on Robinhood Chain. Lock $LEO worth at least 5% of the pot to take the lead; every lock puts a 10-minute clock back to full; when it runs out, the last to lock wins half the pot in ETH and the other half carries over. ## Right now - Status: opens at launch ($LEO has not launched on Pons yet). ## The experiment - We gave 2,578 of our AI agents one question: what keeps a token going up? Together, we ran more than 23,000 tests and spent over 78 million AI tokens finding out. - The answer is this game: last to lock wins, with rules built to push the price up (below). - Film (2 minutes): https://iamleo.xyz/video/zodiac-explainer.mp4, with its transcript on the How it works page. ## For AI agents - MCP server (Streamable HTTP): https://iamzodiac.xyz/api/mcp · tools: zodiac_rules, zodiac_list_games, zodiac_get_game, zodiac_get_grand, zodiac_wallet, zodiac_build_transaction - REST API: https://iamzodiac.xyz/api/v1 · OpenAPI: https://iamzodiac.xyz/api/v1/openapi.json - GET /api/v1/rules: The rules in short, every sign, and the shared contracts - GET /api/v1/games: All twelve games and the Grand game: pot, prize, entry, clock, leader - GET /api/v1/games/{sign}: One sign’s game (leo, $LEO or iamleo.xyz) - GET /api/v1/grand: The Grand game across every sign - GET /api/v1/wallets/{address}: A wallet’s tokens, prizes waiting and referral rewards - POST /api/v1/tx: Any action as unsigned transactions to sign with your own wallet - Actions (POST /api/v1/tx): buy-and-lock, lock-tokens, pay-out, claim, unlock, pay-out-grand, claim-grand, claim-referrals. Each comes back as unsigned transactions for the user's own wallet to sign; nothing is sent and no key is held. ## How it works - Enter: lock $LEO worth at least 5% of the pot, for 24 hours. Buy & lock with ETH in one step, or lock $LEO you already hold. - Clock: every lock puts it back to 10:00. - Win: when it runs out, the last to lock gets half the pot in ETH; the other half starts the next round. Anyone can send the winner their prize. - Money: every trade pays 2%; about 1.7% reaches the game, which puts 40% into the pot, 10% into the Grand game and 50% to the team. - Grand game: one pot across all twelve signs. A lock worth at least 5% of the Grand pot enters it too; the last entry when its 10-minute clock runs out wins half. - Referrals: a wallet's referrer is the link of its first Buy & lock, on any sign. Each later Buy & lock pays its referrers 20% of the team's share of that buy's fees: 70% to the direct referrer, 30% to theirs. ## What nobody can do - Nobody (not the team, not us) can withdraw a pot, a prize, referral rewards or locked tokens. - Nobody can mint a token, pause a game, upgrade the code or change the rules. - Locked tokens go back to their owner after 24 hours, and anyone can send a winner their prize. ## How the design pushes upward - Every entry is a buy: Buy & lock spends ETH on the token at the market price. - The game only ever buys: it has no way to sell, and prizes are paid from the ETH pot. - Winning the lead back takes another lock, and with Buy & lock another buy. - The entry grows with the pot (at least 5% of it), so each new lead takes a bigger lock. - The rush comes at the end: every late lock puts the clock back to 10:00. - Locked tokens are off the market for 24 hours, winners' too; the supply is fixed at 1,000,000,000 per token. - Every buy and sell pays 2%, and part of it fills the pots; half of every pot carries over. - Twelve clocks and one Grand game run at once, and referrers earn on every Buy & lock they bring, for good. - This is how the rules are built, not a promise of profit. Prices can fall; locked tokens cannot be sold for 24 hours. Nothing here is financial advice. ## Contracts (Robinhood Chain, chain id 4663) - $LEO token: launches on Pons soon - SignGame (this sign's game): deploys at launch - GrandGame: 0x332f049df48eEdc07A7984bd821683156AC7513f (https://robinhoodchain.blockscout.com/address/0x332f049df48eEdc07A7984bd821683156AC7513f) - Referrals: 0x624bb8940Fb3E253Fb899EF1faCD55473A8015F3 (https://robinhoodchain.blockscout.com/address/0x624bb8940Fb3E253Fb899EF1faCD55473A8015F3) - Source: https://iamleo.xyz/contracts/SignGame.sol, https://iamleo.xyz/contracts/GrandGame.sol, https://iamleo.xyz/contracts/Referrals.sol ## Pages - [Overview](https://iamleo.xyz/): the prize, the clock and who is winning - [How it works](https://iamleo.xyz/how-it-works): the rules, where the money comes from, referrals - [Contracts](https://iamleo.xyz/contracts): what the contracts do and can't do, how the design pushes upward, the code - [Lab](https://iamleo.xyz/lab): the experiment, a simulation to run, and the agent API and MCP server - [Activity](https://iamleo.xyz/activity): every lock and winner - [Grand game](https://iamleo.xyz/grand) - [All twelve signs](https://iamzodiac.xyz/llms.txt)
