The bets to look for are the "corner numbers" of dozen 2 & 3:

Doz 2 "corner numbers": 13,15,22,24.

Doz 3 "corner numbers": 25,27,34,36.


Trigger: Wait until either Doz 2-corner numbers hit OR Doz 3-corner numbers hit. When this event occurs, bet those corner-numbers not hit.

For an example, if one of Doz 2-corner numbers (13,15,22,24) hit; Then you bet the Doz 3-corner numbers: 25,27,34,36. With 4 numbers progression, (until hit).

Likewise, if one of the Doz 3-corner numbers (25,27,34,36) hit; Then you bet the Doz 2-corner numbers: 13,15,22,24. With 4 numbers progression, (until hit).


4 numbers progression 1 1 1 1 1 1 1 1 2 2 2 2 3 3 3 4 4 5 6 7 8 9 10 12 14 16 18 20 23 27 30 35 40 46 52 59 68 78 89 101 116 132 151
