The Labouchere Roulette Strategy: Sequence Betting Guide
The Labouchere System (also known as the Cancellation System) is a structured, goal-oriented roulette progression. Instead of blindly doubling your bets after a loss, this strategy uses a custom mathematical sequence to spread your risk. If you can clear the sequence, you are guaranteed to hit your exact profit target.

The Core Mechanics: How the Labouchere Works
The goal of the Labouchere is to completely cross off every number in a predetermined line. The sum total of the numbers in your starting sequence is your exact profit target. You must strictly play Even-Money bets (Red/Black, Odd/Even, High/Low) for the math to hold up.
- 1. Write Your Sequence: Determine your profit goal. If you want to win £10, write a sequence that adds up to 10. (e.g., 1 – 2 – 3 – 4).
- 2. Determine Your Bet: Your stake is always the sum of the furthest left number and the furthest right number. (1 + 4 = £5 Bet).
- 3. If You Win: Cross off the two outer numbers you just used. Your sequence is now simply 2 – 3. Your next bet will be 2 + 3 = £5.
- 4. If You Lose: Do not cross any numbers off. Instead, take the amount you just lost (£5) and add it to the far right of the sequence. Your new sequence is 1 – 2 – 3 – 4 – 5. Your next bet will be 1 + 5 = £6.
You continue this process until all numbers are crossed off. Once the line is empty, you have achieved your exact original profit target, and the session ends.
Tracking the Sequence (Crucial Step)
Unlike flat betting or the Martingale, you cannot play the Labouchere strictly in your head. Because the sequence grows and shrinks dynamically based on wins and losses, you must track it visually to avoid catastrophic staking errors.
Whether you use a digital notepad on your phone or a physical pen and paper, accurate tracking is mandatory to clear the line safely.
Worked Example: Clearing a Sequence
Here is a simulated session starting with the target sequence: 2 – 3 – 4 – 5 (Target Profit: £14).
| Spin | Current Sequence | Bet Amount | Result | New Sequence |
|---|---|---|---|---|
| 1 | 2 – 3 – 4 – 5 | £7 (2+5) | Loss | 2 – 3 – 4 – 5 – 7 |
| 2 | 2 – 3 – 4 – 5 – 7 | £9 (2+7) | Win | |
| 3 | 3 – 4 – 5 | £8 (3+5) | Win | |
| 4 | 4 | £4 (Only number left) | Win | Line Cleared (+£14) |
The Danger: Sequence Escalation
The mathematical hook of the Labouchere is that you cross off two numbers for every win, but only add one number for every loss. It implies you only need a 33.4% win rate to clear the line. However, this ignores the terrifying reality of sequence escalation during a losing streak.
If you suffer five consecutive losses starting with a 1 – 2 – 3 – 4 sequence, your line rapidly bloats into:
1 – 2 – 3 – 4 – 5 – 10 – 15 – 25 – 40
Your next required bet is now £41. Your overall risk exposure has skyrocketed exponentially compared to your initial £5 bet. You must have a rigid Stop-Loss limit in place to prevent a brutal sequence from wiping out your entire deposit.
The Reverse Labouchere (Positive Progression)
To completely eliminate the risk of catastrophic sequence escalation, many modern players flip the rules. The Reverse Labouchere is designed to capitalize on long winning streaks while minimizing risk during losing periods.
- The Reverse Rule on a Win: Instead of crossing numbers off, you add your winning bet amount to the end of the sequence. (Capitalizing on the hot streak).
- The Reverse Rule on a Loss: Instead of adding numbers, you cross off the outer numbers you just played. (Reducing your exposure as you lose).
The Catch: While the standard Labouchere requires you to win ~34% of the time to profit, the Reverse variant requires a significant, clustered hot streak (winning well over 50% of the time in a short window) to generate a net positive return.
Essential Bankroll & Table Selection Rules
You must play European or French roulette. American wheels have a 5.26% house edge, which will dismantle your sequences much faster. French tables with La Partage are mathematically superior.
If you have a small bankroll, add zeros to your starting line (e.g., 0 – 0 – 1 – 2 – 2). This dilutes your early bet sizes, allowing you to survive cold streaks longer before the stakes escalate.
Ready to Test the Sequence?
Always check the math and odds before you begin. Keep your starting sequence small, use even-money bets, and track your numbers perfectly.
