This progression method can be applied to any numbers bet, in any system.

+1 bet for each hit, and increase bet +1 after X spins (as long 1 unit is bet in the ordinary progression)

For an example I did a short test with 6 numbers. Amazing results.

For 6 numbers progression (36/6=6-1=5) first 5 steps is 1 1 1 1 1.

So, +1 bet after each 5th step without a hit.

Another example. 4 numbers (36/4=9-1=8): 1 unit is bet for 8 spins in the normal progression.

So, that means +1 each 8th spin without hit, and +1 for every hit etc. 


General rule is +1 bet after a cycle ends minus one


For Even Chances, a cycle is 2: +1 Each spin
For 1 dozen/column, a cycle is 3: +1 after 2 spins
For 1 doublestreet, a cycle is 6: +1 after 5 spins
For 1 corner, a cycle is 9: +1 after 8 spins
For 1 street, a cycle is 12: +1 after 11 spins
For 1 split, a cycle is 18: +1 after 17 spins
For 1 number, a cycle is 37: +1 after 36 spins


I just want to mention this progression method, because I think its absolutely great - it can survive much longer than ordinary progressions and your bankroll will JUMP to mindblowing amounts when it hits (even if you had a long bad streaks before) etc.
