Fast rounds — 4 coins, Even or Odd

House Edge: 1%

Xóc Đĩa is a Vietnamese folk gambling game played for centuries: four two-sided White/Red coins are covered by a bowl on a plate, shaken together, then revealed. An odd count of Red coins (1, 3) wins ODD; an even count (0, 2, 4) wins EVEN. DODEN brings the game on-chain in full: betting, pool matching, the result and payouts all happen publicly on the blockchain.

Fairness

Each round's result comes from a third-party provably-fair randomness service native to its chain — Chainlink VRF on EVM, Switchboard on Solana — with the seed and proof stored on-chain forever; tap any round in the history to verify it yourself. The house is funded by a community bankroll pool: contributors absorb the unmatched side together and earn a share of the house fee from every round.

Frequently asked questions

How does Xoc Dia work?: Betting is open for a short window each round — the countdown on the table is the round's real clock. Pick ODD (LE) or EVEN (CHAN), with a minimum stake of 10 USDT. When betting closes, a provably-fair VRF (Chainlink on EVM, Switchboard on Solana) reveals 4 coins (each White=0/Red=1); an odd count of Red (1,3) wins ODD, an even count (0,2,4) wins EVEN. The winning side is paid ×1.98 on its matched stake.
Why did I bet 1000 but received only 870?: This is a PLAYER-VERSUS-PLAYER round: the ODD and EVEN sides match each other's money, and the house only covers the IMBALANCE — up to what its payout fund allows. If you are on the heavier side, the part of your stake beyond what can be matched never enters the round: it is refunded in full at settlement. Everyone on that side is scaled by the same ratio — matched stake = your bet × (side accepted ÷ side total). So ×1.98 applies only to the MATCHED part, and a 1000 bet on a crowded side may have only a few hundred actually in play. Click the round in history for the full breakdown.
Can I bet both LE and CHAN in the same round?: Yes. Multiple bets, both sides allowed in the same round. Every tx audited.
