Math
Roulette probability
AskCasino answers the question intent: what are the odds, and why a streak does not forecast the next number. For payout tables / spin rules → Signal Roulette.
Base odds (European)
- Red or black: 18/37 ≈ 48.65%
- Zero: 1/37 ≈ 2.70%
- Straight up: 1/37 ≈ 2.70%
- American (0+00): even-money ≈ 47.4%
Colour streaks
Seven blacks in a row does not raise the chance of red. The wheel has no memory. What rises is only the chance of having already seen a long streak somewhere across many spins — not the conditional odds of the next one.
