Roulette Strategy

Unlike card games, every game of Roulette has the same odds. This means that players rely on betting strategies in order to get the most out of a game of Roulette. While each have garnered excellent results, the casino will always have an advantage over the player with the house edge, and therefore no betting strategy is foolproof. Here are six strategies Odds & Chances’ find to be the most effective.

Martingale System

Invented in 1700s France, the Martingale System has the player betting solely on a double or nothing outside bet (Black or Red, Odd or Even, 18 of 36 Numbers). It does not matter which of the six one-to-one payout areas you place your chips, because they all have an equal chance every spin. If you lose, you double your wager and play again. If you win, you keep your wager the same. This way, whenever you win, you cover your previous losses.


Using the same double or nothing betting areas, many people prefer to do the exact opposite as the aforementioned system. Instead of doubling your bet every time you lose, you double your bet every time you win, and keep your bet the same every time you lose. The idea is that lucky winning streaks will be even hotter, and losing streaks will have less of a consequence.

d’Alembert Strategy

Named after Jean le Rond d’Alembert, who incorrectly theorized that the likelihood of a coin landing on the tails side increases every time it lands on the heads side, this variation of the Martingale is an intriguing one. Set a unit value and increase your bet by that unit value when you lose, and decrease it by the unit value when you win. If you win as many times as you lose or better, you’ll profit. This is instead of doubling your wager every time you win or lose. It’s much more conservative and the losses are much less devastating, though the immediate winning potential is lower.

Fibonacci Strategy

You may have heard of this Italian mathematician’s famous number sequence before. In the sequence, the next number is the last two numbers added together. If the sequence starts at one, it would be 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, and so on. You still bet on a one-to-one outside space (Odd or Even, Black or Red, Half the Numbers), then bet forward in that sequence every time you lose. If you win, go back two numbers in the sequence and bet from there. For example, if you start with a $5 bet and lose four times in a row, the progression would be $5, then $5 again, then $10, then $15. If you win on the fifth bet, you would return to $5. If you win on the sixth, you would have lost more times than you won, but still came out with a profit.

The Ian Fleming Strategy

Ian Fleming, author of the James Bond novels, invented this strategy that he swore by. It requires $198 on a single bet in European Roulette, and is meant to be one bet for one large payout. You place $140 on the high number (19-36) outside bet, place $8 on each of the individual numbers 13 through 18, and $10 on the 0 green pocket. If the ball lands in any pocket 1-12, the bet is lost, but if the ball lands in a pocket 19-36, you profit $82. If it lands in one of the 13-18 pockets, you profit $82, and if it lands in the 0 pocket, you profit $152.

Set Limits

The most important betting strategy to implement is to play in predetermined sessions. Decide how much you’re willing to lose, decide on a win limit, and decide on the session length. A good example would be a player willing to lose $200 in a session, and decides to walk away if he wins double what he was willing to lose, loses the $200, or his timer goes off after two hours. Set aside any winnings, take a break, then start the process completely fresh next time you’re in the mood to play. Sticking to this system religiously will garner the most enjoyable results at the casino more so than any aforementioned strategies.
