System 7

[Andre Chass]

This method compares two displacements and tries to find a repetition in the same number of ball or displacement's position. 
It's important to know that we need a complete displacement to start playing. 
For example: 

4   (ball #1) 
9   (ball #2) 
27 (ball #3) 
34 (ball #4) 
25 (ball #5) 
3   (ball #6) 
3   (ball #7) 
13 (ball #8) 
11 (ball #9) 
33 (ball #10) 
23 (ball #11) 
21 (ball #12) 
[...] 
19 (ball #36) 

Once a first displacement is completed, we can start playing. 
We have to bet the displacement's anterior, middle and posterior numbers, depending on the number of ball of our new displacement. 

On our example, if we started playing in ball #3 of the new displacement (or general ball #39), we should bet numbers 9, 27 and 34. If we missed, then we should bet on numbers 27, 34, 25. 

As you can see in the picture below, the displacement moves forward until a repetition is found.


As usual, the betting process includes progressions, so we have to be extremely careful. A safe way of playing it, is waiting 11 or 13 balls in the new displacement, without any burns (remember a burn is if the system achieved victory and you didnt'play it). 
If this is the case, we should wait until the displacement is completed and start over with a new one. Once we started, we can use a standard progression, incrementing the betting chips if the balance of winning is negative. 

This way, we can play for 22-25 balls, plus the 11 we have waited would totalize 36 balls.
