What makes Labouchère different from Martingale?

Martingale simply doubles the stake after every loss. Labouchère starts from a chosen profit target written as a sequence of numbers, and bet size is the sum of the first and last numbers on that list — a fundamentally different, goal-driven structure rather than a fixed doubling rule.

Do you need to win most bets to profit with Labouchère?

No. Because each win cancels two numbers from the sequence while each loss only adds one, a player can reach the target profit while winning fewer than half of their total bets, since wins are sized larger on average than losses.

Does the Labouchère system beat the house edge?

No. It only changes how wins and losses are distributed within a session; the underlying house edge on the even-money bet stays the same. A long losing streak can also push the required stake up quickly, the same core risk shared by all progressive betting systems.

The Labouchère system explained (the only progressive system that lets you set an exact profit target)

Last updated: 2026-07-30 · Written by Priya Nair

Labouchère, also called the cancellation system or split Martingale, is a progressive betting system built for even-money roulette bets — red/black, odd/even, high/low. Unlike Martingale, which simply doubles the stake after every loss, or Fibonacci, which follows a fixed number sequence regardless of what a player actually wants to win, Labouchère starts from a specific profit goal chosen in advance and builds the entire betting pattern around reaching it.

Setting the goal: a sequence of numbers, not just a stake

Before placing a single bet, a player picks a profit target and writes it as a sequence of positive numbers that sum to that target — usually expressed in units rather than a currency amount, so a $100 goal split into ten $10 units might be written as the sequence 2-2-2-2-2 or any other combination summing to 10 units. This sequence, not a single number, is what actually drives every bet that follows.

How a bet is sized and settled

Each bet stakes the sum of the first and last numbers currently on the list — for the sequence 2-2-2-2-2, that's 2+2=4 units on the first bet. If the bet wins, both numbers used are crossed off (canceled) from the list, and the next bet uses the new first-and-last pair. If the bet loses, the amount lost is added to the end of the list instead of being removed, which grows the sequence rather than shrinking it. The goal is reached once every number on the list has been crossed off — at that point, the sum of all winning bets minus all losing bets equals exactly the profit target set at the start.

Why it doesn't need a majority of winning bets

Because each win cancels two numbers while each loss only adds one, a player using Labouchère can reach their target while winning fewer than half of their total bets — the wins simply need to be sized larger, on average, than the losses, which the cancellation mechanism handles automatically as the sequence shortens with wins and lengthens with losses. This is a real structural difference from flat betting or a system like Martingale, where every bet risks the same relationship to the last.

Where it breaks down: the same trap as every progressive system

A long losing streak keeps adding numbers to the end of the list, and since each bet stakes the sum of the current first and last numbers, the required stake can grow quickly — the same structural risk covered in progressive betting systems explained for Martingale and Fibonacci. No sequencing method changes the underlying house edge on red/black or odd/even; Labouchère only changes how wins and losses are distributed across a session, and a bad enough run can push the required bet size past a table limit or a player's bankroll before the sequence ever clears.
