Roulette Strategy Video Information:

The Labouchere roulette strategy or bets cancellation system.
The player must write a list of positive numbers, whose sum total equals that of the aformentioned end numbers.
At the start of each new spin, the player will bet the sum total of the first and last number on the list.
If the spin win, then the player will then strike the two numbers off the list, the first and last one.
As opposite, if the player loose, the numbers are added back to the back of the list instead.
And this will go on until all the numbers have been crossed out from the list, as the Labouchère system do when spins are winning with this strategy on roulette.
