Xoc Dia
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.
