How this figure is established
Fixed by the rules of the game rather than by a configuration setting. A wheel with 37 pockets and a 35-to-1 straight-up payout returns 36/37 of total amount staked, and every standard bet on the wheel returns the same fraction.
The derivation
A single-zero wheel has 37 equally likely pockets: 0 and 1 to 36. A straight-up bet on one number wins with probability 1/37 and pays 35 to 1, returning 36 units (the 35 won plus the 1 staked). Expected return per unit staked = (1/37) x 36 = 36/37 = 0.972973, so RTP = 97.2973% and the house edge is 1 - 36/37 = 1/37 = 2.7027%. Every other standard bet on the wheel gives the same figure: an even-money bet wins with probability 18/37 and returns 2 units, giving (18/37) x 2 = 36/37 again. The result depends only on the count of pockets and the paytable, both of which are fixed by the rules of the game, so no operator disclosure is needed to establish it.
What this record cannot tell you
- This figure describes the wheel as defined above. An operator offering a variant rule — a different payout, an extra pocket, or a partial return on zero — is offering a different game with a different figure.
- Long-run return says nothing about a session. Over a few dozen spins the outcome is dominated by variance, not by the 2.7% edge.
- Live-dealer and electronic implementations can differ in side bets, which carry their own and usually worse mathematics.
A long-run return says nothing about a session. Over a few dozen plays the outcome is dominated by variance, not by the edge. Why RTP does not describe your session.
