Roulette simulator
Pick a wheel, place play chips, press Spin, and watch how the house edge works on every bet you make.
The simulator needs JavaScript. The rules, payouts and house edge are below.
How to use the roulette simulator
The simulator sits right above this text. It works like a real roulette table, but you only use play chips.
- Choose a wheel – European, French, American, or triple zero.
- Pick a chip – tap the chip value you want to bet.
- Tap the table – each tap places a chip on that spot. Tap again to add more.
- Press Spin – the ball lands, winning bets are paid, and losing chips are taken.
- Check your stats – see your result next to what the house edge predicts.
You can change the wheel at any time and compare how each one feels.
Start with one simple bet, like red or black, so you can follow what happens on each spin.
Choose your wheel: what each one changes
All four wheels pay the same for the same bet. What changes is the number of zeros, and that changes the house edge.
- European – one zero, 37 pockets. House edge: 2.70%. More about European roulette.
- French – the same wheel as European, plus the La Partage rule: when the ball lands on the zero, you get half of an even-money bet back. House edge on those bets: 1.35%. More about French roulette.
- American – two zeros (0 and 00), 38 pockets. House edge: 5.26%, about 1.95 times the European edge. More about American roulette.
- Triple zero – three zeros: single zero, double zero and triple zero, 39 pockets. House edge: 7.69%. More about triple zero roulette.
| Wheel | Pockets | Edge on red/black | Edge on one number |
|---|---|---|---|
| European (single zero) | 37 | 2.70% | 2.70% |
| French (La Partage) | 37 | 1.35% | 2.70% |
| French (En Prison) | 37 | 1.39% | 2.70% |
| American (0 and 00) | 38 | 5.26% | 5.26% |
| American, Atlantic City rule | 38 | 2.63% | 5.26% |
| Triple zero (0, 00, 000) | 39 | 7.69% | 7.69% |
More zeros means more pockets where most bets lose, while the payouts stay the same. See the full wheel layout for the order of the numbers.
Which bets you can place on the table
There are two groups of bets on the roulette table.
- Inside bets – on single numbers or small groups: straight (35 to 1), split (17 to 1), street (11 to 1), corner (8 to 1), and line (5 to 1).
- Outside bets – on big groups: dozens (2 to 1), columns (2 to 1), and red/black, odd/even, low/high (1 to 1).
| Bet | Numbers | Pays | Chance to win | House edge |
|---|---|---|---|---|
| Straight up One number | 1 | 35 to 1 | 2.70% | 2.70% |
| Split Two touching numbers | 2 | 17 to 1 | 5.41% | 2.70% |
| Street A row of three | 3 | 11 to 1 | 8.11% | 2.70% |
| Trio 0, 1, 2 | 3 | 11 to 1 | 8.11% | 2.70% |
| Corner Four numbers in a square | 4 | 8 to 1 | 10.81% | 2.70% |
| First four 0, 1, 2, 3 | 4 | 8 to 1 | 10.81% | 2.70% |
| Six line Two rows, six numbers | 6 | 5 to 1 | 16.22% | 2.70% |
| Dozen 1–12, 13–24 or 25–36 | 12 | 2 to 1 | 32.43% | 2.70% |
| Column A column of twelve | 12 | 2 to 1 | 32.43% | 2.70% |
| Red or black Eighteen numbers | 18 | 1 to 1 | 48.65% | 2.70% |
| Even or odd Eighteen numbers | 18 | 1 to 1 | 48.65% | 2.70% |
| 1–18 or 19–36 Eighteen numbers | 18 | 1 to 1 | 48.65% | 2.70% |
Bigger payouts mean the bet wins less often. On a given wheel, almost every bet has the same house edge.
Two exceptions:
- On the French wheel, even-money bets have a lower edge of 1.35% because of La Partage.
- On the American wheel, the top line 0-00-1-2-3 has a higher edge of 7.89%.

What the numbers on your screen mean
The simulator shows a few live numbers so you can see the math behind the game.
- House edge of your bets – the average share of your bets the house keeps over time, for the chips now on the table.
- Biggest possible win – the most you can win on the next spin with your current bets.
- Session result – how many play chips you are up or down since you started.
- Expected result – what the house edge predicts for the total you have bet so far.
For example, on the European wheel the average loss is $2.70 for each hundred dollars bet. On the American wheel it is $5.26.
In a short session, your result can be far above or below the expected line. The more spins you play, the closer your result as a share of the total you bet tends to move toward the house edge.
The gap in chips between your result and the expected result is luck. Over many spins, that gap tends to get small compared with the total you have bet.
Fair, random spins – and why no system beats them
Every spin uses a cryptographic random number generator. Each pocket has an equal chance on every spin.
- The result is drawn before the wheel animation starts. The animation only shows the outcome.
- Each spin is independent. Past numbers do not change the next one.
- There are no hot or cold numbers – only random results.
No betting system changes the house edge of the bets it uses. Doubling after losses or following patterns does not lower the rate at which you lose over time.
You can test this yourself with the system tester or read about the Martingale system.
Try any system you like here – it costs only play chips, and the stats show what really happens.

Questions
Is this roulette simulator free?
Yes. The simulator is free and uses play chips only. There is no real money and no sign-up.
Which roulette wheel has the lowest house edge?
The French wheel with La Partage has the lowest edge on even-money bets at 1.35%. The European wheel is 2.70%, the American wheel is 5.26%, and triple zero is 7.69%.
Are the spins in the simulator random?
Yes. Each result comes from a cryptographic random number generator and is drawn before the animation starts, so every pocket has an equal chance on every spin.
Can a roulette simulator help me win at roulette?
No. It helps you learn the rules and the math, but no system or practice changes the house edge, and the house wins over time.
What does the expected result in the session stats mean?
It is the average result the house edge predicts for the total you have bet. Your real result can differ a lot in a short session because of luck, but over many spins your loss as a share of the total bet tends to get closer to the house edge.
