Roulette Systems: 30 Betting Strategies Tested and Compared
We ran 100,000 simulated sessions of eight popular roulette systems on a European wheel, and every one of the 30 systems below has a guide that works out its odds.
No roulette system beats the house edge. Every system in our simulation lost about 2.7p for every £1 bet, the European wheel’s edge. What a system changes is how you lose: small and steady, or rarely but heavily.
Our verdict
The Best Roulette System for What You Want
There is no system that wins in the long run, but there are clear differences in risk. Based on our simulation of eight systems, with a £100 bankroll and £1 starting bet:
Masse Égale
Flat staking bet the least, so it lost the least. It never ran out of money in our test.
Paroli
Only raises the stake with money it has just won, then resets. The biggest bet never went above £4.
Fibonacci
Finished ahead more often than any other system in our simulation, but its losing sessions were large.
Martingale
A coin flip in our test. Half the sessions ended ahead, half ran out of money before 100 spins.
Romanovsky
Wins on 32 of 37 pockets, but £8 goes on every spin, so it lost the most on average.
Labouchere
The line grows after every loss. It ran out of money more often than any other system in our simulation.
Simulation results
We Tested 8 Roulette Systems Over 800,000 Sessions
Each system played 100,000 sessions on a single-zero European wheel. Every system faced the same spins, so the only difference is the staking. Ranked from the smallest average loss to the largest.
“Typical session” is the median result: half of sessions did better, half did worse. “Biggest bet” is the largest stake seen in 99% of sessions. “Ran out of money” means the next bet was bigger than the money left.
The edge never moved
Every system lost between £2.66 and £2.80 for every £100 bet. That is the house edge on a European wheel, whatever the staking plan.
Winning often is not winning
Fibonacci finished ahead in 74% of sessions, yet still lost £5.78 per session on average because its losing sessions were so large.
You lose what you bet
Romanovsky wins most spins but bet £797 per session on average, and lost the most. Flat £1 bets totalled £100 and lost the least.
How we ran the test
- 100,000 sessions per system, 800,000 in total, using the same random spins for every system on a 37-pocket European wheel.
- Each session starts with £100 and a £1 base bet, and lasts up to 100 spins. It stops early if the next bet is bigger than the money left.
- Progression systems bet on red (18 of 37 pockets, pays 1:1). Paroli resets after three wins in a row. Fibonacci steps back two places after a win. Labouchere uses a 1-2-3-4 line and starts a new line once it is cleared.
- Romanovsky bets £3 on each of the first two dozens and £1 on two corners in the third dozen: £8 per spin covering 32 pockets.
- Table limits never came into play: with a £100 bankroll, the money ran out first. Each guide in the directory below works out its system’s odds, and most have a calculator or simulator.
The limits
What a Roulette System Can and Cannot Change
A system can change
- How much you stake after a win or loss
- How quickly the next bet grows
- How much of the wheel you cover
- How volatile a short session feels
- Where you set a stop point
A system cannot change
- The house edge on the wheel
- The chance of the next independent spin
- A casino’s table minimum or maximum
- The expected return per pound bet
- A losing run that has already happened
Bankroll and table limits
The Bet That Catches Players Out
The first bet is never the problem. It is the bet after four, five or six losses. Work backwards from the largest stake you would be willing to place, not forwards from a harmless-looking £1.
Five Martingale losses from £1
Five losing bets of £1, £2, £4, £8 and £16 cost £31. The next bet has to be £32, just to win back £1.
So £1 Martingale needs £63 to survive five losses in a row, and a £5 unit needs £315. In our test, 50% of £100 Martingale sessions ran out of money within 100 spins.
- Bet 1£1
- Bet 2£2
- Bet 3£4
- Bet 4£8
- Bet 5£16
- Next bet£32
Set the unit first
Choose it from the worst run you are willing to fund, not from the first spin.
Check the table maximum
A progression stops working as written once the next bet is above the table limit.
Fix a stop point
A stop-loss limits the size of a session. It does not improve the odds of the next spin.
How systems work
The Four Main Types of Roulette System
Flat staking
The bet stays the same after every result, as in Masse Égale.
Good for: keeping losses small and predictable.
Loss progressions
The stake rises after a loss: Martingale, D’Alembert, Fibonacci.
Main problem: bets grow while you are already behind.
Win progressions
The stake rises after a win: Paroli, Contra D’Alembert.
Main difference: it risks recent winnings, not fresh money.
Coverage layouts
Chips spread across dozens, corners or numbers: Romanovsky, 64%.
Trade-off: more numbers covered means more money on every spin.

Roulette System FAQs
What is the best roulette system?
No system beats the house edge. In our 800,000-session test, flat staking (Masse Égale) lost the least, about £2.72 per £100 session, and never ran out of money. Paroli kept the biggest bet at £4. If you want frequent small wins, Fibonacci finished ahead most often (74%), but it ran out of money in 23% of sessions.
Do roulette betting systems actually work?
They work as staking rules, not as a way to beat the wheel. Every system in our test lost between £2.66 and £2.80 for every £100 bet, which is the 2.7% house edge on a European wheel. A system changes how your results are spread out, not the odds.
Which roulette system wins most often?
In our test, Fibonacci finished ahead in 74% of sessions, D’Alembert in 55% and Martingale in 49%. But winning often is not the same as winning money: all three still lost money on average because their losing sessions were large.
What is the best roulette system for a small bankroll?
Flat staking, such as Masse Égale, puts the least pressure on a small bankroll because the stake does not rise after a loss. It still does not improve the odds, so the unit size and stop point matter more than the system name.
How much bankroll do I need for Martingale?
To lose five bets in a row and still place the next Martingale bet, you need 63 units: 31 already lost and a 32-unit next bet. At £1 per unit that is £63; at £5 it is £315. In our test, 50% of £100 Martingale sessions with a £1 starting bet ran out of money within 100 spins.
What is the difference between positive and negative progression systems?
A negative progression raises the stake after a loss, as in Martingale, D’Alembert and Fibonacci. A positive progression raises the stake after a win, as in Paroli and Contra D’Alembert.
Can I use a roulette system on live dealer or Lightning Roulette?
A staking rule can be followed on live or software tables, subject to the casino’s terms. Live betting windows give you less time to work out a complicated sequence. A non-multiplied straight-up win in Lightning Roulette pays 29:1 rather than the standard 35:1, so not every standard example carries across.
Do stop-loss and take-profit limits improve roulette odds?
No. They set a boundary for the session, which can stop a bad run becoming a much bigger loss, but they do not change the probability or expected return of any spin.
Are roulette betting systems legal in UK casinos?
Yes. Choosing your own stakes and betting pattern is legal. A casino may still ban bots or software that places bets for you, so follow the site’s rules.
