Frequently Asked Questions

How is roulette played?

In roulette, a croupier spins a wheel containing numbered pockets (0–36 in European, 0–36 plus 00 in American). Players place chips on the table layout to bet on where the ball will land. If the ball lands on a number or group that matches your bet, you win your stake back plus a payout. If not, you lose your stake.

How do I calculate odds and payouts in roulette?

The payout ratio for any bet is calculated as (Total numbers on wheel ÷ Numbers covered by bet) − 1. For example, a Straight Up bet covers 1 number on a 37-number European wheel: 37/1 − 1 = 36 to 1. Multiply that ratio by your stake to find your profit, then add your stake back to get your total payout.

What is the difference between European and American roulette?

European roulette has 37 pockets (0–36), giving the house an edge of 2.70%. American roulette adds a double-zero (00), creating 38 pockets and raising the house edge to 5.26%. This makes European roulette statistically more favorable for players on almost every bet type.

What are the odds on 0 and 00 in roulette?

Betting straight up on 0 (or 00) pays 35 to 1, the same as any other single number. In European roulette the win probability is 1/37 ≈ 2.70%, while in American roulette it is 1/38 ≈ 2.63%. The zeros are what give the casino its house edge.

What is the house edge in roulette?

The house edge is 2.70% for European roulette and 5.26% for American roulette on most bets. The exception is the Five Number bet (0, 00, 1, 2, 3) in American roulette, which carries the highest house edge of 7.89% and is generally considered the worst bet on the table.

What is expected value and why does it matter?

Expected value (EV) is the average amount you can expect to win or lose per bet over the long run. In roulette, EV is always negative because the house edge means the casino keeps a small percentage of every wager. Knowing your EV helps you understand the true cost of each bet and compare bet types rationally.

Which roulette bet has the best odds?

Outside bets — Red/Black, Odd/Even, and High/Low — offer the highest win probability (roughly 48.6% in European roulette) but the lowest payout of 1 to 1. If you want the best balance of payout and probability, European outside bets are the most player-friendly option on the table.

Can I use this calculator for multiple bets at the same time?

This calculator evaluates one bet type at a time. To calculate multiple simultaneous bets, run each bet separately and add the individual net profits together. Keep in mind that if the ball lands on a number that wins for one bet, it may cause other bets to lose.
