This system was famously used by an English guy called Norman Leigh in 1966. He took a team of 12 guys down to Nice with the objective of breaking the casino. They were eventually banned from every casino in France. (Having said that, be aware that Norman Leigh has made most of his money from the sale of his book that covers his exploits: Thirteen Against The Bank)
Norman Leigh reasoned that if he took what he considered the easiest system with which to lose money in roulette: the LaBouchere, and reversed it, he would actually have the system with the best chance of winning.
Just a recap on the LaBouchere system:
In the Labouchere, the player writes down a series of numbers:
1, 2, 3, 4.
You bet a number equal to the sum of the first and last numbers, so in this example 5. If you win, you cross off the numbers at the end:
x-1-x, 2, 3, x-4-x
On your next bet, you add the remaining numbers and again bet 5 (in this example, anyway).
After all the numbers are crossed off with wins, you begin a new series of numbers. If you lose, you need to add the value of the last bet to the series. So in this case you would have
1, 2, 3, 4, 5
So now you are betting 6. if you lose again, you are betting 7 etc etc.
Norman Leigh reversed the system and created the Reverse Labouchere or Reverse Labby, by adding numbers after he won, not after he lost. This would allow him to capitalise on winning streaks.
He convinced 12 people to come with him to the south of France to play his Reverse LaBouchere System. (They all paid their own way and put up their own money).
Between the team, the gang of 12 were able to cover all “50-50″ bets (red-black, odd-even, high-low) at 2 tables. The winning runs from one colour or number size were then placed in a special account. Norman Leigh took a 10% cut, and then the spoils were split evenly among the players, regardless of the individual winners
Did you spot the clever guy in this story? Yep, it’s Norman Leigh, who was taking his 10% without risking his own money.
