Mister labouchere is a negative progressive system, that is sometimes also called the “Cancellation ” , “Crossout”, “, “Labby” or “Split Martingale”.

The system is mostly used in Blackjack or Roulette, but can actually nicely be used also in online slots.

The idea, behind the system is based on a sequence of numbers.

If you win you cross out the winning numbers until you completed the whole series.

1. Start with writing down a series of numbers on a sheet – for example: 1 2 3 4 5 6.

2. Your first bet should be the value of the two outside numbers – in our case 1 + 6 = 7. This is the size of the bet you need to wager.

If you win – cross out the chosen numbers ( 1 and 6) and move to the inner numbers (2 and 5) that equal again 7 and bet this number.

If you lose – add your number to the end of the line. Your new line should look like 1 2 3 4 5 6 7 and your new bet should be (1 + 7) 8.

If you complete the series, then you should have more money in your account than you started with and you can start all over again.

The only negative side of this system is, that you should use also your loss limit. if you keep losing and losing- then you could reach a point, where you just run out of money, because the system requires a large bankroll in case you really lose.

(As you can see, first the game result is defined and only afterwards the reels stop and show it)

Tip: Many Online Casinos allow pressing the button of the slot while the reels are spinning and they'll stop at the time when the button is pressed, but most people don't know that pressing the button in the middle of the game will not affect the results of the game.

The result is defined by a component called R.N.G (Random Number Generator) and this component is not affected by pressing the button in the middle of the game, the slot will show the same result weather or not you'd press the button in the middle of the game.
