The Cancellation Betting System By Henry Labouchere Explained

The Cancellation betting system was invented by a Canadian roulette player named Henry Labouchere. The betting system is to recover from many smaller wins instead of one big one. Many players like to try different options whilst betting, we will go over The Cancellation betting system here.

The Cancellation Betting System Explained

The idea behind this Betting System is that in the long run, 2 events of approximately the same probability will come in pretty much the same amount of times – think even bets in Roulette such as Red/Black, Odd/Even or Pass/Don’t Pass bet in Craps.

This Betting System relies on that happening over the short run as well. The more money you invest, the longer you can run for and the better your chances are of winning in a session, although at the risk of losing more.

How The Cancellation Betting System Works

How The Cancellation Betting System WorksThe aim is to win the equivalent of a number of units. You decide how much as a unit is worth depending on the amount you wish to risk.

For the purpose of this example, we will aim to win 10 units with each unit worth €1 – we will start with a €25 bankroll to try and achieve this.

To start, you need to write down ten 1’s on a piece of paper – so 1 1 1 1 1 1 1 1 1 1 – each number represents a unit. Once all numbers have been crossed off, you will have won 10 units, the aim of the session.

Each time you bet, you need to place a bet equal to the left-hand and right-hand digits. If there is only one digit left, or you don’t have enough bankroll to bet both, you can just bet the left-hand digit.

To start in the above example, you would need to bet 2 units – 1 1 1 1 1 1 1 1 1 1. The 2 red digits are the left-hand and right-hand ones, the sum is 2.

Remember, you are only betting on even-money bets in this Betting System.

If you win, you cross off both numbers, if you lose then the sum of the numbers is placed on the right.

Example of the Cancellation Betting System

Example of the Cancellation Betting SystemAs an example, you win the first bet, cross off the first and last digits, leaving eight 1’s – 1 1 1 1 1 1 1 1.

Next bet, you would add together the left-hand and right-hand digits, again this would equal 2 – 1 1 1 1 1 1 1 1.

Next bet you lose, therefore you add an extra digit on the right that totals the left-hand and right-hand digits. You will now have – 1 1 1 1 1 1 1 1 2.

The next bet would be a total of 3 units – add the left-hand and right-hand digits together – 1 1 1 1 1 1 1 1 2.

If you win, remove the 2 red digits – so you would end up with 1 1 1 1 1 1 1 and would next bet 2 units again.

If you lose, then you add the total bet to the right and would end up with 1 1 1 1 1 1 1 1 2 3. Next bet would be 4 units – 1 + 3.

The idea is that you have as much chance of winning as losing – if you lose then you increase your bet next time to try and win that loss back.

You will either cross out all the numbers and, in the above example, win 10 units, or you will lose your entire bankroll. As mentioned, you can increase or decrease the number of units you would like to win during a session, just start with more or fewer numbers, the total number of 1’s that you would like to win during a session. Remember, the more you are trying to win, the better chance there is of losing.

Why Use The Cancellation Betting System

There are many people who firmly believe they have a betting system that works, that guarantees them and anyone playing it a profit.

This is simply not the case if it was then casinos and other betting establishments would be losing money and closing down. I have never heard of a casino that loses money in the long term and doubt you have either.


Like any betting system, the house will almost always have an edge and will, therefore, win in the long term.

As a player, all you are trying to do is get ahead in the short term and walk away for a profit, using a betting system such as the Cancellation Betting System can help remove some of the decision-making processes and enhance the playing experience.

We suggest that if you want to try out this system you do so use free chips first at one of our recommended casinos.

Once you have got used to the concept, you can try it out for real money.
