How the payout and edge are worked out
total return = stake × (payout + 1) · chance = numbers covered ÷ pockets · house edge = 1 − chance × (payout + 1)
Worked example: $20 on a corner (4 numbers, 8 to 1) on an American wheel. A win returns $20 × 9 = $180. The chance is 4 ÷ 38 = 10.53%, and the edge is 1 − (4 ÷ 38) × 9 = 5.26%, an average loss of $1.05 per spin.
Payouts are set as if the wheel had 36 numbers. The zero (and double zero) is where the house edge comes from, which is why every bet on the same wheel has the same edge, apart from the American top line.
No betting system changes this. Doubling after a loss (Martingale) changes how often you win a session, not the average loss: each spin still costs the same share of what you stake. Test it yourself in the roulette simulator. See how the edge adds up over a session in the house edge calculator.
Questions
How many numbers are on a roulette wheel?
A European wheel has 37 pockets: 0 and 1 to 36. An American wheel has 38: 0, 00 and 1 to 36. Bets pay the same on both, so the extra 00 is what makes American roulette worse for the player.
How do you win at roulette?
No betting system changes the odds: every bet loses the house edge on average, 2.70% on a European wheel and 5.26% on an American one. The best you can do is play a European wheel (ideally with la partage) and set a budget; red or black wins most often, a single number pays most.
What are the chances of winning at roulette?
Your chance is the numbers you cover divided by the pockets: 47.37% for red or black on an American wheel and 48.65% on a European wheel. The calculator shows the probability for every bet.
How much does roulette pay?
A single number pays 35 to 1, a split 17 to 1, a street 11 to 1, a corner 8 to 1, a six line 5 to 1, a dozen or column 2 to 1 and red, black, odd, even, 1–18 or 19–36 pay 1 to 1. Your stake comes back on top.
What does a $10 bet on one number pay?
$350 profit plus your $10 back, $360 in total. The chance is 1 in 38.00 on an American wheel and 1 in 37.00 on a European wheel.
Is American or European roulette better?
European. The single zero gives a house edge of 2.70% against 5.26% on the American wheel with 0 and 00. The payouts are the same, so only the odds change.
What is la partage?
A European rule: when zero comes up, even-money bets lose only half the stake. It cuts the edge on those bets to 1.35%. En prison works almost the same way.
