≈97.3% RTP on single-zero even-money bets; double-zero is lower. Confirm wheel type.
Overview
Roulette is probability theater with fixed pay tables. No betting system overcomes the zero (or zeros).
Rules
Place inside/outside bets before the RNG resolves.
Payouts follow standard ratios (e.g., even-money 1:1, straight-up 35:1) subject to wheel type.
How It Works
Single-zero European: 37 pockets, even-money true odds 18/37, paid 1:1 ⇒ house edge 1/37 ≈ 2.70%.
Double-zero American: 38 pockets ⇒ edge 2/38 ≈ 5.26% on most bets.
Payouts
Higher payouts correspond to lower probabilities. Edge is typically similar across many inside bets on a given wheel.
Examples
$10 on red (single zero): win $10 with p=18/37, else lose $10. EV ≈ −$0.27 per spin.
Strategies
Prefer single-zero when available. Avoid progression systems marketed as “safe.”
RTP
RTP ≈ 97.3% (single zero) or ≈ 94.7% (double zero) for standard bets.
House Edge
Edge comes from the zero pockets. Fancy systems do not remove it.
Variance
Outside bets: lower variance. Straight-up numbers: high variance.
