How this is real: the die is a 0–36 roll from the same mutual commit-reveal as MAY Roulette, and every win window maps exactly to an on-chain RouletteRulesVerifier bet class (e.g. "exact number" = straight 36×, "window of 12" = dozen 3×). Real chain-enforced payouts — no simulation. The house edge on every mode is the roulette zero (~2.7%) minus nothing else; a 1.25% fee applies only to losing stakes at close.
