Following are common European Roulette strategies. Try them at the nearest casino.
The Martingale Strategy
Double your bet after a loss. If the next bet wins, you reclaim your losses + profit equal to your first bet.
Example:
Bet | Result | Math | Balance |
---|---|---|---|
$10 | Lose | $0-$10 | -$10 |
$20 | Lose | -$10-$20 | -$30 |
$40 | Lose | -$30-$40 | -$70 |
$80 | Win | -$70+$80 | +$10 |
- Betting black or red, odd or even, or numbers 1-18 or 19-36 is nearly 50:50 odds. If you double your bet and win, you will recover all your losses + profit equal to your first bet. Continue doubling your bet after consecutive losses until you win.
- Remember Gambler’s Fallacy. For example, the odds of getting a black number is almost 50% every spin, regardless if previous spins have produced all black numbers. The roulette wheel doesn’t remember each spin’s result.
- Be careful if you lose multiple times. Doubling your bet may reach the table maximum, causing the strategy to fail. Modify your strategy before reaching the table maximum. Alternatively, your first bet should be very small.
The 0 decreases the probability of a black or red number slightly below 50:50.
Inverse Martingale Strategy
Double your bet after a win. If the next bet loses, you lose your winnings – losses equal to your first bet.
Example:
Bet | Result | Math | Balance |
---|---|---|---|
$10 | Win | $0+$10 | +$10 |
$20 | Win | +$10+$20 | +$30 |
$40 | Lose | +$30-$40 | -$10 |
$10 | Win | -$10+$10 | $0 |
$20 | Win | $0+$20 | +$20 |
- Betting black or red, odd or even, or numbers 1-18 or 19-36 is nearly 50:50 odds. If your next bet loses, you will lose your winnings – losses equal to your first bet. Do not double your bet after consecutive losses. Return to your first bet and wait until you win.
- Remember Gambler’s Fallacy. The odds of getting black number is almost 50% each time, regardless if previous spins have produced all black numbers. The roulette wheel doesn’t remember each spin’s result.
- Be careful if you win many times. Doubling your bet may reach the table maximum, causing the strategy to fail. Modify your strategy before reaching the table maximum. Alternatively, your first bet should be very small.
The 0 decreases the probability of a black or red number slightly below 50:50.
The D’Alembert Strategy
This strategy benefits the player because roulette table maximum amounts are rarely reached. Players can also make larger first bets because they will not need to double any subsequent bets. Players can enjoy playing roulette for much longer time periods. The D’Alembert strategy slows the game to a comfortable pace..
Example, using $10 increments:
Bet | Result | Math | Balance |
---|---|---|---|
$10 | Lose | $0-$10 | -$10 |
$20 | Lose | -$10-$20 | -$30 |
$30 | Lose | -$30-$30 | -$60 |
$40 | Win | -$60+$40 | -$20 |
$30 | Win | -$20+$30 | +$10 |
$20 | Win | +$10+$20 | +$30 |
$10 | Win | +$30+$10 | +$40 |
The 0 decreases the probability of a black or red number slightly below 50:50.
- Example results and balance, 2 losing bets and 2 winning bets:
# Bet Result Math Balance 1 $10 Lose $0-$10 -$10 2 $20 Lose -$10-$20 -$30 3 $30 Win -$30+$30 $0 4 $20 Win $0+$20 $20
The Fibonacci Roulette Betting Strategy
Fn = Fn-1 + Fn-2 with starting values of F1 = 1, F2 = 1.
E.g. 1, 1, (F3 = F1+F2), (F4 = F2+F3), etc.
The first 15 Fibonacci numbers: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610.
- After a loss, bet the next number in the series. E.g. you lose betting 13, the next bet is 21.
- After a win, the next bet is equal to two steps back in the series. E.g. you win betting 8, the next bet is two steps back to 3.
- You can profit by losing more spins than you’ve won. Be careful, the further you go through the sequence, the more money you lose.
The 0 decreases the probability of a black or red number slightly below 50:50.
