By using different strategies for roulette, players hope to win, but they do not always succeed. Very often, under the slogan "Profitable strategy", the player is offered some cunning, intricate systems that do not carry a practical basis. Such complex, but not necessarily profitable strategies include the Labouchere roulette system. Rather, this strategy should help the player to be collected and suggest the size of the next bet.

The Labouchere strategy is based on the progression of bets, but not the same as in Martingale. Before starting the game, the player must write down numbers from 1 to 9, inclusive, in any order and in any quantity, but it is recommended that 4 and so that the number is even (divisible by two). Let's look at an example right away to make it clear. We wrote down the numbers 1, 3, 1, 4, 2, 5; note that repeating numbers is allowed. Now you need to place a bet on equal chances (red or black, even or odd, etc.), its size will be equal to the sum of the extreme digits, i.e. 1 + 5 = 6, so we bet 6 chips. We were lucky and we won, the next bet will be 5 (guess why?), Because those numbers that have played are crossed out and the next extreme ones enter the turn, and these are 3 and 2. The game goes on until the hidden numbers are completely crossed out, so what the fewer numbers, the faster it ends.

Of course, the winnings will not be permanent. In case of losses, you will need to add a number to the hidden numbers, which is equal to the lost bet. That is, if the bet burned out during the first spin, then we add the number 6 and get the following order of numbers: 1, 3, 1, 4, 2, 5 and 6. The next bet will be made in the amount of 7, because 1 + 6 = 7.

There is also a reverse version of this system, i.e. in case of winnings, add the size of the bet, and in case of losses, cross it out. In any case, when all numbers are crossed out, the player will remain in positive territory.
