Connect your TON wallet, pick your stake, and we'll match you with an opponent. Then it's pure 50/50 random: the roulette spins and whoever rolls higher takes the whole pot. 0.2 TON from every bet goes to the fee smart contract.
0.2 TON from every bet is really sent via TON Connect to the fee wallet. The duel itself and opponent matchmaking run on the server (Python + SQLite); the token stake is tracked in the game ledger. On-chain escrow and automatic token payout to the winner require a separate jetton contract. This is a meme utility, not a financial service. DYOR, play for fun.
