LUPYNPlay PLAYER GUIDE · ROBINHOOD CHAIN
Your first race
starts here.
Connect a wallet on Robinhood Chain, enter a race with RUB, and claim your prize or refund.
Real tokens. Entries use real RUB on Robinhood Chain mainnet, and every transaction costs a little real ETH for gas. There is no faucet. Only enter what you can afford to lose, and check that playing is allowed where you live. Never enter your recovery phrase or private key on the game site.
1Get your wallet ready
Use a desktop browser with MetaMask from its official website. You need a little ETH on Robinhood Chain for gas and the RUB you want to enter with. The game does not sell or hand out either.
- Open the race lobby.
- Click Connect wallet and approve the connection in MetaMask.
Connecting shares your public wallet address with the game. It does not enter a race or approve token spending.
2Use Robinhood Chain
The game asks your wallet to switch to Robinhood Chain. Check the details below before approving.

Optional: import the stake token so your balance shows in the wallet. Importing does not add funds.

4Enter a race
- Pick one of the six horses while the race shows Betting open. Each race opens and closes at fixed, published times.
- Enter an amount. The entry panel shows the race's rules before you sign: the pool split, the per-wallet and per-race limits, your weighted chance and what you would win if your horse wins.
- Confirm the RUB spending approval in MetaMask if asked, then confirm the separate entry transaction. Approval alone is not an entry.
Stakes are held by the race contract itself. When a race settles, 80% of the pool goes to the winners, shared by their stakes on the winning horse, 10% to the Crew Lock reserve (held until Phase 2), 5% to Development and 5% is burned. If Crew Lock never opens, the reserve's 10% stays locked and isn't paid out. A race whose pool stays below its minimum is cancelled and every stake refunded. Payouts depend on the final pool; they are not fixed odds.
5Wait for the result
After betting closes, the race asks Chainlink VRF on Arbitrum One for a random number, carried both ways by Chainlink CCIP. That usually takes a few minutes, not seconds. The winner is drawn on chain from that number, so anyone can check it.
If the number does not arrive before the race's published deadline, or nobody backed the winning horse, the race is voided and every stake can be refunded in full.
6Claim
- Open My payouts. Prizes and refunds are listed separately.
- Click Claim and confirm the transaction in MetaMask. The RUB arrives in the same wallet.
Claims never expire. Keep a little ETH for the claim's gas, and use the same wallet address you entered with.
Stuck? Start here.
The network or account is wrong
Unlock MetaMask, check the connected account, and switch to Robinhood Chain (chain ID 4663). Finish or dismiss any older wallet prompt first.
Approval succeeded, but there is no entry
Approval only allows spending. Confirm the separate entry transaction before betting closes, then check the game's confirmation.
Entries are not open
Races may be paused, or entries may not be switched on yet. Settlement, refunds and claims keep working while paused.
The result is taking a long time
The random number crosses two chains. Wait for the published deadline; if it passes without a word, the race is voided and your stake becomes claimable.
