x = Number of wins y = Number of losses z = Numbers on original list When: x + z ≤ y * 2 The system has failed, and all numbers on the line are crossed completely out. Given an infinite line, the Labouchère System when played by the player requires a winning percentage of at least 33.34% to complete.
Let q be the probability of losing (e.g. for American double-zero roulette, it is 20/38 for a bet on black or red). Let B be the amount of the initial bet.
