Don’t be confused or discouraged by the multitude of names. It is an extremely interesting and quite simple strategy for roulette. It gives good results too, except in the very rare cases of extremely bad streaks of roulette spins. You know… those days when the roulette wheel really hates your guts!
Each session starts by writing down an initial betting sequence. For simplicity purposes we will describe the classic version of the cancellation system, with a 1-2-3 starting betting sequence.
- You write three numbers in sequence e.g. 1 2 3. The sum of these numbers (in this case 1 +2 +3 = 6) will be the profit when you finish this session.
- Bet the sum of the first and last number in your sequence
- When you win erase the two numbers you have bet (the first and the last in your sequence)
- When you lose, you add the sum (your bet) at the end
add 4 to the end
add the 5 to the end
bet: 1+5 =6
erase 1 and 5
add 6 to the end
bet = 2+6=8
add 8 to the end
erase 2 and 8
add 9 to the end
erase 3 and 12
bet 4 +9 = 13
erase the 4 and 9
End game. Start over again by writing 1,2,3
In 11 spins, with 6 losses and 5 wins, we won 6 units. Not bad at all.
Theoretically, your bet selection makes no difference to the success of the system. However "Follow the Last" is Kavouras' preferred bet selection on even chances. Follow the Last means betting on the repetition of the last outcome (after red has come we bet on red etc.). With this bet selection you hope for long strings of the same outcome (Red, Red, Red etc.) and you loose when the outcomes alternate (Red-Black-Red-Black etc.)
Variations and modifications of the Cancellation System
The Labouchere strategy, is not only effective, but also very flexible. Once you understand the underlying principles, it invites you for modifications and it inspires you to make your own roulette strategy based on it. It is the mother of many great roulette systems. Indeed, many different versions of the split martingale have seen the light of day. Some times the differences are unimportant and sometimes they are huge, transforming the Labouchere to a totally new system. The variations of the basic strategy can be divided in four categories as follows.
Modifications of the initial bet sequence
The initial betting sequence is not written in stone. You can change it to your hearts content. This can have quite an influence on how the progression and the bet amounts develop on the course of the session.
If you start with higher numbers and/or a longer sequence , like 3,4,5,6 you have more profit every time you finish your session [18 units profit instead of 6 with the classic 1,2,3 sequence ], but your sessions become more dangerous and the bets escalate faster.
If your initial sequence is 3,4,5,6 you gain 18 units every time you finish an attck, instead of 6 units with the classic 1,2,3 sequence
On the other hand, if you want more safety you can start with just one number instead of a sequence of three numbers. There is even a super safe version of the Labouchere, which starts with 10 zeros (or even more!) and a 1. In this case the starting sequence looks something like this:
Our first bet is 1unit. On a loss we replace the last 0 (next to 1) with 1 and we continue to bet 1 unit. You can read more about this system, also called Johnson progression,in our roulette forum.
Split the betting sequence when losing
Like in all negative progression, the weakness of Labouchere is that in a worst case scenario the bets get high really fast. The solution to avoid high bets and high possible losses is to split the sequence into “lighter”, less dangerous sequences. This done like this:
Say after 24 spins your sequence looks like this:
22, 26, 35, 41, 46, 55, 66, 79 (=340)
You can transform this sequence into 3 separate sequences. The new sequences can be whatever we like. The only requirement is that if added together, they must have a total that equals the total of the original sequence 22+26+35+…+79=340
A: 10, 15, 20, 25, 30, 35, 40, 45 (=220)
B: 15, 15, 15, 15 (=60)
C: 15, 15, 15, 15 (=60)
In this case we continue the betting with sequence A, which is much less aggressive and dangerous than the original sequence. Furthermore, after this sequence is completed, we will begin our next 2 sessions with sequences B and C instead of the original “1, 2, 3” sequence. After all these 3 sessions are terminated we start our next attack with the original “1, 2, 3” sequence as usual.
Reverse Labouchere strategy
Some crazy people even reversed the Labouchere from a negative progression, (increasing bets when you lose) to a positive progression (increasing bet as you win). This strategy is (obviously) the reverse of the Labouchere progression:
You add one number at the end if you win, and you erase the two numbers if you lose. Specificaly:
- Bet the sum of the first and last number in your sequence
- When you lose erase the two numbers you have bet (the first and the last in your sequence)
- When you win, you add the sum (of your bet) at the end
With this system you experience many relatively small loses. You are opting for the rare event that you have more than double wins than losses. In that case you can win tremendous amounts of money. A good question is “when do you stop the progression and take the money and run?”. Because eventually the favorable run will end and you will lose all your winnings fast. What you need in this kind of systems is to determine a “stop win” instead of a “stop loss”.
Legent has it that this roulette strategy was first documented by Seton Robert Beresford in the 1920’s and was put to good use by Norman Leigh in Nice in 1966. In his book “Thirteen against the bank”, Leigh describes how he beat a casino with a team of thirteen players who played all 6 even chances at the same time in two roulette tables. They used no win limit. They let the progression increase to infinity, till they hit the roulette table limit or the casino admitted its loss and casino officials draped the table with the classic black cloth.
