How to play the Labouchere roulette betting system successfully take just a bit of time to understand the concepts. The Labouchere is sometimes called the cancellation system or split Martingale. It can be used with close to even bets and is most popular on even-money payoff roulette bets like black or red, even or odd, and 1-18 and 19-36.
To play the Labrouchere roulette system, a player chooses a starting bankroll, writes down a sequence of numbers, and then makes a wager equal to the first and last numbers on their list. Small starting numbers are required to fit most bankrolls. If the player starts with 1-2-3-4-5-6, then the first bet is 7 units (1+6). If this bet wins, the player crosses out the 1 and 6 and continues on with a bet of 7 units(2 + 5). If this bet loses, the player adds the 7 to the end of the existing line and now has 2-3-4-5-7. At this point the new bet is 9 units (2 + 7).Betting
If the player starts with a $100 bankroll and begins the betting with a $7 bet, the system continues until all the numbers are crossed out, which gives the player a winning session, or the starting bankroll is lost. A larger starting bankroll increases the chances that the system will be completed successfully. Because the wagers increase with losses, it is considered a losing progression system.Theory
Each time the player wins a bet, two numbers are crossed off the list, but a losing wager adds only one more number to the sequence, so the theory is that the Labouchere system will be successful because the player only needs to win 33.34 percent of their wagers. Even-money wagers at roulette offer 18 chances to win and 20 chances to lose (on a wheel with a "0" and a "00"). Betting an even-money wager at roulette returns 47.37 percent, higher than is needed to complete each list of numbers.Drawbacks
Because players have limited bankrolls and roulette games have table limits, the Labouchere system has drawbacks. Obviously when a player's bankroll is lost, the system fails, but likewise, it fails when the next bet in the sequence exceeds the table limits or maximum bet.Reverse Labouchere
The Labouchere system can be used in reverse, which makes it a winning progression system. In this case, the player is hoping to have a long run of winners and reach the table maximum or quit with a predetermined about. If the player starts with 1-2-3-4-5-6, then the first bet is 7 units (1+6). If this bet wins, then a 7 is added to the end of the line to now show 1-2-3-4-5-6-7. The next bet in this winning progression system is 8 units (1 + 7). If this wager loses, then the player crosses off the number from each end of the list (1 and 7) and then bets the two remaining numbers (2 + 6). Some players prefer to start the reverse Labouchere with a numbers list that ebbs and flows, such as 1-2-3-4-3-2-1.Theory
Each time the player wins a bet, a number is added to the line. When the player loses a wager, two numbers are added to the list. In this fashion, the list will grow quickly and the player will fail to complete the list if they lose more than 33.34 percent of their bets. Even-money wagers at roulette offer 18 chances to win and 20 chances to lose (on a wheel with a "0" and a "00"). Betting an even-money wager at roulette returns 47.37 percent, higher than is needed to complete each list of numbers.
However, when the player does have a string of winning wagers, the stakes will grow quickly and provide a much higher return than when playing the standard Labouchere. Should the player actually complete or bust the line, or break the table limit, they will have to start a new line or quit. Their return will be substantial.Drawbacks
Because the casino only has to win 33.34 percent of the wagers to beat the player in the reverse Labouchere, the system fails much more often than is succeeds. Although a successful run of spins can produce a winner, in the long run, a player has to endure many small loses before capturing a winning session.The Final Word
All betting systems are designed to give the player some specific options with regard to how much to wager. No system wins all the time. If they did, there would be no casinos offering games of chance. The Labouchere offers many small wins to coincide with each large loss. The reverse Labouchere offers many small losses to coincide with each large win.
