Quick answer: No roulette strategy can beat the house edge. Every spin is independent, and every standard bet carries the same edge: 2.70% on a European wheel and 5.26% on an American one. Systems like the Martingale, Fibonacci or D’Alembert only change how your wins and losses are spread out. The best “strategy” is to play European or French roulette, set a budget and stop when you reach it.

Popular roulette systems compared
| System | How it works | What really happens |
|---|---|---|
| Martingale | Double your bet after each loss | Frequent small wins, but a losing streak can hit the table limit or empty your bankroll |
| Reverse Martingale (Paroli) | Double your bet after each win | Small losses, but one loss wipes out a winning run |
| D’Alembert | Raise your bet by one unit after a loss, lower it by one after a win | Slower swings than the Martingale, same house edge |
| Fibonacci | Follow the Fibonacci sequence after losses | Bets grow more slowly than the Martingale, but losses still pile up |
| James Bond | Spread one bet across high numbers, a six line and zero | Covers many numbers at once, but leaves 1 to 12 uncovered |
None of these systems change the house edge. They change the size and pattern of your bets, not the odds of any spin. Put any spread of bets into our roulette calculator and you will see the same 2.70% edge (5.26% on an American wheel).

Why systems can’t beat roulette
- Each spin is independent: the wheel has no memory of past results.
- Every standard bet has the same house edge, so no combination of bets can turn it in your favour.
- Table limits and your bankroll stop progressive systems before they can recover a long losing streak.
What actually helps
- Pick the right wheel: European (2.70%) over American (5.26%).
- Use French rules where offered: La Partage or En Prison cuts the edge on even-money bets to 1.35%.
- Avoid the five-number bet on American tables (7.89% edge).
- Set a budget and a stop point, and never chase losses.
- Know the odds of every bet; see our roulette odds guide, which also lists every number on the wheel.
The Martingale betting system in numbers
The Martingale is the most popular roulette system: bet on an even-money outcome such as red, and double your stake after every loss. When you finally win, you recover all your losses plus one starting unit. It feels safe because you win most sessions. Here is what a losing streak looks like with a $5 starting bet:
| Bet number | Stake | Total lost if it loses |
|---|---|---|
| 1 | $5 | $5 |
| 2 | $10 | $15 |
| 3 | $20 | $35 |
| 4 | $40 | $75 |
| 5 | $80 | $155 |
| 6 | $160 | $315 |
| 7 | $320 | $635 |
| 8 | $640 | $1,275 |
By the eighth bet you are staking $640 to come out just $5 ahead, and many tables have a maximum bet that stops you before that. How often does that happen? On a European wheel, the chance of losing an even-money bet is 19/37, about 51.4%:
| Streak | Chance (European) | Roughly |
|---|---|---|
| 5 losses in a row | About 3.6% | About 1 in 28 |
| 7 losses in a row | About 0.94% | About 1 in 106 |
| 10 losses in a row | About 0.13% | About 1 in 784 |
A 1-in-106 streak sounds rare, but if you start a new Martingale sequence many times a night, you will meet it sooner or later. When you do, one big loss wipes out dozens of small wins. Over time the result matches the house edge, just with very uneven swings.
Labouchère and other progression systems
The Labouchère (or cancellation) system has you write a sequence of numbers, such as 1-2-3-4. Each bet is the sum of the first and last numbers. When you win, you cross both off; when you lose, you add the amount you lost to the end. When all numbers are crossed off, you’ve won the sum of the original sequence. Like the Martingale, it can produce steady small wins and then a run of losses that sends stakes soaring.
Every progression system has the same flaw: it changes how much you bet, not your chance of winning each spin. No sequence of negative-expectation bets adds up to a positive one.
Sector bets: Voisins, Tiers and Orphelins
On European and French tables you’ll often see “call bets” that cover sections of the wheel rather than the layout:
| Bet | What it covers | Chips |
|---|---|---|
| Voisins du Zéro (neighbours of zero) | 17 numbers around the zero | 9 chips |
| Tiers du Cylindre (third of the wheel) | 12 numbers opposite the zero | 6 chips |
| Orphelins (orphans) | The 8 numbers left over | 5 chips |
These bets are fun and quick to place, but they are made of ordinary splits, streets and corners, so the house edge is still 2.70%.
What roulette really costs per hour
A useful way to judge any strategy is to work out its expected cost. Multiply your stake by the number of spins and by the house edge. If you bet $10 a spin for 40 spins an hour:
| Wheel | Total bet per hour | Expected loss per hour |
|---|---|---|
| European (2.70%) | $400 | About $10.80 |
| American (5.26%) | $400 | About $21.04 |
Faster games mean more spins and a higher hourly cost, even at the same stake. Slowing down is one of the simplest ways to make your budget last.
A simple roulette bankroll plan
- Decide your session budget before you sit down, and treat it as spent.
- Keep each bet to a small share of that budget, for example 1% to 2%, so a bad run doesn’t end your session in minutes.
- Set a stop-loss and a win goal. When you hit either, stop.
- Stick to European or French tables and even-money bets if you want the slowest, steadiest play.
- Never increase stakes to chase losses. That is exactly how progression systems fail.

Roulette strategy FAQs
Is there a winning roulette strategy?
No. Every spin is random and every bet has a house edge, so no system can guarantee a profit.
Does the Martingale work?
It wins small amounts often, but a losing streak can wipe out your bankroll or hit the table limit.
What is the safest roulette bet?
Even-money bets like red or black win most often (48.65% on a European wheel), but they have the same edge as any other bet.
Which roulette should I play?
French or European. Avoid American roulette, which has nearly double the house edge.
