Система "+- 0 System from GB"

You play this system on even bets (1-1), eg: Red/Black, Odd/Even. High/Low

Step 1: First SPIN you do not bet, just wait for the outcome

Step 2: Second SPIN, you bet on the opposite of the First SPIN outcome.

Step 3: Third SPIN

Step 3A: If you WIN on step 2 then do not play on the Third SPIN, just wait for the outcome. Or to make it simpler assume you are back to Step 1.

Step 3B: If you LOOSE on step 2 then play the Third spin, by betting on the opposite outcome of the second Spin, at this stage you have started the progression.

Step 4: Fourth Spin

Step 4A: If you Win at step 3B do not play on the Fourth Spin, just wait for the outcome. Or to make it simpler assume you are back to Step 1.

Step 4B: If you LOOSE on step 3B then play the Fourth spin, by betting on the opposite outcome of the Third outcome, at this stage you are in the progression.

Step 5: Hope you got it

The Progression:
Single zero: 1-2-2-3-3-3-4-4-4-4-5-5-5-5-5-6-6-6-6-6-6-7-7-7-7-7-7-7 etc
Double Zero: 1-2-3-4-5-6-7-8-9-10 etc
Beware of the progression, and always know where you are, it is rather confusing.

you go one level up when you loose, one level down when you win. And this does not mean you are increasing your bet, it depends where you are in the progression, so you could be on your third 3 and go for 4, or you could be on your second 3 and go for your third 3 etc…
