The Normal Leigh Labby progression is a betting system used in the game of Roulette. It was developed by mathematician Leigh Labby in the mid-19th century and is still used today. The system involves betting on the same set of numbers for a predetermined number of rounds. After each win, the bet is increased by one unit, and after each loss, the bet is decreased by two units. The goal of the system is to maximize the player's chances of winning and minimize the risk of a large loss.
