Roulette Odds Calculator: Calculate Your Total and Per Bet Hit Probability Instantly

The Real Odds Behind Every Roulette Bet

That extra "00" on American wheels isn't just for show - it fundamentally changes your winning chances. Let's look at what this means in practice.

Ever watched several reds or blacks appear in a row and wondered about the probability? 

Here's what the math tells us:

Consecutive same color probability:

• Two consecutive spins: 23.6% in European vs. 22.4% in American roulette vs. 21.3% in Triple 0 roulette
• Three consecutive spins: 11.5% in European vs. 10.6% in American roulette vs. 10% in Triple 0 roulette

Same number appearing consecutively:

• Two-time repeaters: Just 0.073% in European (1-in-1369) vs. 0.069% in American (1-in-1444) vs. 0.066% in Triple 0 (1-in-1521)

These numbers reveal a mathematical truth: each spin is completely independent of previous results. The wheel has no memory or pattern, contradicting many popular betting systems.

The house edge also varies significantly:

• Triple 0 roulette: : 7.69%
• American roulette: 5.26% (except for the five-number bet at 7.89%)
• European roulette: 2.70%
• French roulette: As low as 1.35% for even-money bets (with the La Partage rule)
