Definition The Labouchère system is a gambling strategy used primarily in games with even-money bets, such as roulette. It is a progressive betting system designed to achieve a predetermined profit through a sequence of bets determined by a list of numbers.
Overview The Labouchère system, also known as the cancellation system, is employed to manage wagers in casino games. It is most commonly used when placing even-money bets, such as betting on red or black in roulette. The goal of this system is to realize a specific profit amount by systematically structuring the size of each bet. Unlike other betting systems such as the Martingale, which doubles bets after losses, the Labouchère uses a sequence of numbers to determine the bet amount and adjusts the sequence based on outcomes.
Etymology/Origin The system is named after Henry Du Pré Labouchère, a British politician and journalist from the 19th century. Although it is attributed to him, there is no solid evidence confirming that he invented or used the system for gambling. Accurate information is not confirmed about his direct involvement in its development.
Characteristics
- The process begins by writing down a sequence of numbers (e.g., 1, 2, 3), where the total sum represents the desired profit.
- The bet amount is the sum of the first and last numbers in the sequence.
- If the bet wins, the first and last numbers are removed from the list.
- If the bet loses, the amount lost is added to the end of the list.
- The process continues until all numbers are canceled out (indicating the profit goal has been met) or until the player stops due to constraints like bankroll limits.
- The system does not alter the house edge and does not guarantee profit; it merely structures the betting pattern.
- It requires strict adherence to the sequence and can lead to rapidly increasing bet sizes during losing streaks.
