There is a great variety of roulette betting systems the players employ in a pursuit of luck while playing roulette casino game.

"Gambler's fallacy"

With the vast popularity of roulette a whole set of various beliefs has emerged to shape roulette myths and superstitions. Most of these beliefs are based on false assumptions, "Gambler's fallacy" being the most popular of them. Due to this assumption, each result of coin tossing or roulette wheel spins etc. is related to all past and future results. It means that if a certain group of numbers, say Black, has been hit for several spins, this imbalance shall be necessarily evened and the next spin has to end by hitting Red.

This fallacy aroused the development of most roulette betting systems. In fact, no betting system can truly influence the roulette probabilities. Roulette is a game of mere chance, and the above mentioned assumption is just a fallacy. Nevertheless, the use of roulette betting systems may help you manage your bankroll more carefully and avoid dramatic losses.

Martingale betting system

Martingale betting system is often called the most popular of all roulette betting systems, even though it is quite risky and, in the long run, unprofitable.

To apply Martingale betting system, the player is supposed to double the amount of bets every time he or she loses. Every win means that the player sticks to the size of a previous bet. This betting system deals with even money bets and is based on the fact that every loss is eventually followed by win. In fact, it is fairly easy to exceed the maximum limit for bets at a roulette table and be unable to refund all losses.

Fibonacci sequence

The Fibonacci betting system is based on the Fibonacci numeric sequence. In this sequence, every next number is the sum of two previous numbers, e.g. 0 - 1 - 1 - 2 - 3 - 5 - 8 - 13 - 21 - 34, etc. According to Fibonacci betting system, the player should increase the bets by adding the numbers as they are added in Fibonacci sequence. Even as the Fibonacci system is less risky compared to the Martingale that requires doubling the bets, it is recommended to make the lowest possible initial bet not to exceed the maximum betting limit.

Labouchere betting system

According to Labouchere betting system, or Cancellation system, the player bets the sum of each first and last number in the sequence he or she chooses due to their own liking. With every win the two numbers are to be crossed out, every loss requires adding the sum of the lost bet to the end of the sequence. This system is marked by a certain flexibility as the player may choose how to build the numeric sequence, and it doesn't require doubling the bets, but it is still unprofitable in the long run, especially if the player hits a losing streak.

D'Alembert betting system

The D'Alembert betting system is based on a progressive pyramid model. Due to this model, the player increases the bet by a certain set amount in case of each loss and reduces it by the same set amount every time he or she wins.

Other roulette betting systems

There is a whole set of other roulette betting systems, more or less popular:

• Oscar Grind betting system according to which one makes even money bets and continues betting until a single unit which was lost gets refunded.
• The Thomas Donald system implying one may bet up to 3,000 times his or her initial betting amount. It presupposes that the number of wins and losses during certain period of time is fairly even.
• Makarov system where the player makes bets of set amounts on the same single number.
