Roulette is a game with a rich history. Over the years a number of strategies have been formed by thinkers in the game, and while there are never any guarantees in gambling – particularly at the roulette wheel – here are some approaches you might consider.
The Martingale System
The Martingale system involves doubling your bet after every loss on even money bets. At the roulette wheel, for example, doubling your bet on red or black after each loss will eventually and instantaneously recover all your previous losses. The long-term success of the Martingale system depends on two conditions: that there is no limit on money earned from a single bet, and that the gambler has infinite wealth.
Without infinite wealth), a bad string of luck will quickly bankrupt any followers of the Martingale system.
The D’Alembert System
The D’Alembert system can be seen as a more cautious variation on the Martingale system, where instead of doubling your bet with each loss, you only increase the bet by one unit, and decrease it by one unit after a win.
The Paroli System
The Paroli system doubles the wager after each winning number until three consecutive wins have been achieved. To start, a single unit wager is placed on an even money bet. If it loses, repeat the same single unit bet until it wins.
After a win, bet two units; if this bet loses, return to wagering one unit. If the two-unit bet wins, double the next wager to four units – the final bet of the progression, win or lose. The Paroli system seeks to capitalise on the fortunes of winning and losing streaks by raising the stakes on winning runs, and reducing them on losing runs.
The Fibonacci System
The Fibonacci system takes a famous mathematical sequence and applies it to the roulette wheel. This sequence starts with a zero and a one, with each subsequent number the sum of the previous two, e.g.: 0 1 1 2 3 5 8 13 21 34, and so on. At the wheel, the Fibonacci system ignores the 0 at the start, with each other number representing one betting unit.
Let’s say a unit is €5. Starting at one, place this bet until it loses. At this point, move to the next number in the sequence – the number equates to two units, which in this case is €10. This rule is applied to every loss, moving along the sequence accordingly and increasing your stake after each losing wager.
If your wager wins, you move back two spaces along the sequence, e.g., winning at number 21 means your next wager is placed at eight units.
