How this is real: one spin = one real 0–36 roll from the same mutual commit-reveal as MAY Roulette, settled on the on-chain RouletteRulesVerifier. Your payout tier maps exactly to a verifier bet class (💎 JACKPOT 36× = straight, 🍒 3× = dozen window, etc). A win window is drawn for your tier; the reels decode the actual on-chain number: outcome N in your window → three matching tier symbols; outside → a deterministic losing combo (reel_i = symbol[(N·primeᵢ + i) mod 8], never three-of-a-kind). No client RNG decides money — the chain does. House edge ~2.7% (the roulette zero); 1.25% fee on losing stakes at close.
