The rules
How GREED works
- 1. Load your game balance.Deposit SOL once — one wallet approval. After that, entering, cashing out and locking in the next round happen instantly, with no wallet popups. Withdraw back to your wallet any time.
- 2. Enter during the lobby.Each round opens with a 20-second countdown. Pick your amount and enter.
- 3. Watch it climb.The rocket lifts off and the multiplier climbs — 2× after about 12 seconds, up to a 10× max at 40 seconds.
- 4. Cash out before it flies away.Hit Cash out and your payout locks at that multiplier. At a random moment the rocket flies away — anyone still riding loses their entry. Reach 10× and you're paid the max automatically.
- 5. Winnings land in your balance.No claim step. Want in on the next round while this one flies? Lock it in and you're entered the moment the next lobby opens.
Provably fair
Each round's fly-away second is fixed before anyone enters: the house commits a hidden secret on-chain, which is combined with a Switchboard oracle random value that didn't exist yet when the secret was committed. Players can't predict it and the house can't choose it; when the rocket flies away the secret is revealed and anyone can check the result on-chain. The odds carry a 5% house edge, larger the higher you ride: about 1 round in 21 reaches 10×.
