Three of a kind pays the big number; any two matching pays the small one. The rug never pays.

The math lives in the contract. Reel weights and every payout are public constants — nobody can retune the machine after you sit down. Provably fair: the house signs the hash of a secret before your spin exists, and the reels come from keccak(secret, blockhash), which neither side can steer. Non-custodial: the contract pays you itself, and if the croupier ever goes quiet you take your stake back with refundBet.
