Cancellation Roulette Strategy (Labouchere)

The cancelation roulette strategy which is sometimes called the Labouchere, is a system were you decide how much you want to win and then you break this number up into several smaller bets and create your own betting pattern. It is best to have lots of small sessions rather than having one big one as I shall show you below. It is a system that is used on the even money bets only – red/black, odd/even and high/low.

Construct Your Numbers

Your numbers can be whatever you like and your win if you eventually complete the line is the sum of your starting numbers. Here’s an example of a starting line

1 – 2 – 3 – 4 – 5 – 4 – 3 – 2 – 1

The sum of those numbers added up is 25, so the profit will be £25 if you complete the line. Here are the four rules that you need for the system.

  1. The amount you bet on each spin is the left hand number added to the right hand number. In the example above, the first bet would be £2 because the left and right numbers are both £1.
  2. If you win a bet, cross the left and right numbers off your line and forget about them.
  3. If you lose, add the number that you just bet to the right hand side of your line.
  4. Once all the numbers have been crossed out, your session is finished, either start a new line or quit altogether.

You will probably need a pen and paper to use the system properly and keep on top of the numbers, so make sure you have them to hand ready. Now for an example using the line above as a starting point.

First bet is £2 and you win. The line is now 2 – 3 – 4 – 5 – 4 – 3 – 2

Second bet is £4 and you lose. The line is now 2 – 3 – 4 – 5 – 4 – 3 – 2 – 4

Third bet is £6 and you win. The line is now 3 – 4 – 5 – 4 – 3 – 2

Fourth bet is £5 and you win. The line is now 4 – 5 – 4 – 3

Fifth bet is £7 and you lose. The line is now 4 – 5 – 4 – 3 – 7

Sixth bet is £11 and you win. The line is now 5 – 4 – 3

Seventh bet is £8 and you lose. The line is now 5 – 4 – 3 – 8

Eighth bet is £13 and you win. The line is now 4 -3

Ninth bet is £7 and you win. The line is now completed.

The example above contains more wins than losses to show you how the line reduces in size as you win but in reality, you won’t get more wins than losses so you should prepare for your lines to take much longer to complete.

One drawback with this system is when you have a bad run, the numbers will soon add up and they can linger on your line for many bets, keeping them at higher amounts than you would like. On the upside, when you lose, only one number gets added to the line but when you win, two get taken off so it’s possible to have twice as many losses as wins and still come out in plus.

Pros of this system – It’s flexible to however you want to play and you control the amounts that you bet.

Cons of this system – It requires constant maths, concentration and probably pen and paper. After a losing run, there will be multiple high numbers on your line that only wins can remove.
