Any self-respecting player whose main game is French roulette will never give away their secrets or systems. But sometimes that information does leak out. Below are several of the main roulette playing systems, which their advocates claim can make your time at the table easier and more profitable.

System one: martingale

The essence of this system is that the player must place bets in turn according to certain rules. You bet alternately on red and on black, based on the colour that came up on the wheel. Say we bet ten dollars on red; if the bet wins, we move it to black. If the bet loses, we double its size.

System two: mirror numbers

This system suits players who like and know how to work through different combinations. On the roulette table there is a set of numbers that have "mirrors": 6 and 9, 12 and 21, 13 and 31, 23 and 32, plus a pair of "inverted" numbers, 16 and 19, 26 and 29. These are easy enough to remember and just as easy to use in practice. The rule is this: from the moment a number with a mirror comes up, the player starts betting on its mirror pair, from the tenth spin through to the twentieth. The number usually comes up.

System three: system numbers

The player needs to find a "system" number. Suppose 14 came up, and within the hour 24 came up as well. According to probability theory, in the following hour the numbers 4, 14, 24 or 34 should come up. That is what you bet on. The main thing is to spot the pattern.

System four: betting on the chances

Under this system it is important for the player to notice systematic jumps between dozens, colours or columns. Suppose the last dozen came up - in that case the player should bet on the two preceding ones. The same goes for columns.

System five: against the statistics

Under this system the player must never bet even a minimum amount on the numbers in the statistical top five. Their sights should be on the bottom ten numbers.

In closing, it is worth noting that the systems above work quite decently on American roulette as well. Worth a try!
