The original DeFi Roulette promises / carried into luck.fun
One contract-governed casino account across every game — add funds, play within disclosed limits, then request cash-out to your connected wallet. Available and locked balances live on-chain, and the cash-out request, claim, and refund states stay independently visible.
Roulette binds every closed round to Chainlink VRF — the operator never draws, holds, or commits the deciding number. Slots commit a server seed hash and your client seed on-chain at openSession and settle by re-running the exact spin math.
How it works →Your casino balance is built on on-chain available and locked amounts, not an operator-only ledger. Cash-out requests, claims, and refunds are readable straight from the CasinoVault contract and every settled round.
Contract coverage →European single-zero math: 36× straight, 2× red/black, $0.10 minimum. The maximum bet scales with the live house bankroll, which the contract itself holds — check it from the table before you play.
