House rules & odds
A European single-zero wheel: 37 pockets, one zero pocket, no double zero. The winning pocket is a single crypto.randomInt(37) draw taken before the wheel animation starts — the animation is just a rendering of a result that already exists.
Every bet pays true odds for the pockets it covers: straight up 35:1, columns and dozens 2:1, red/black, odd/even and high/low 1:1. There is no en prison or la partage rule, and no bet on this table is priced worse than any other.
RTP 36/37 = 97.297% on every single bet type — a house edge of 2.703%. A straight-up bet wins 1 spin in 37 and returns 36× the stake; an even-money bet wins 18 spins in 37 and returns 2×. Both come to the same number, which is exactly what a fair single-zero wheel does.
