At a quick glance it seems that the Cancellation system is difficult to understand, but that it only seems so. You'll see it yourself if you spend a couple of minutes to thoroughly study the system.

The Cancellation roulette system, as many other systems, is based on the bet progression. For better understanding write down the numbers from zero to ten. Then, to calculate your bet you should add two numbers from the column: the uppermost number and the lowermost. You don't have to be a Professor of Mathematics to get the result equal to eleven. If your bet wins, you should cross off these numbers and use the following pair of numbers for the next bet.

You might have already noticed that in case of winning, regardless of the current bet size, the next bet according to the Cancellation system will always be equal to eleven. Now, let's understand how to bet if you lose. In this case, you should not cross off the numbers in the column. You should add 11 to the lowermost not-crossed-off number of the column and again add two numbers (the uppermost and lowermost). Please, pay your attention to the example which shows you the result of two consecutive wins and one loss.

The game session according to The Cancellation roulette system ends when all the numbers of the column are crossed off.

If you paid your attention, you must have noticed that, in case of losing, the bet will increase in an progression, and in case of winning, the next bet will be the same as the first bet of the game.
