Notepadding this Matrix idea for Dozen betting...

MATRIX 7 GRID (DOZEN STRATEGY
=======================

Record consecutive lines of 7 dozen results horizontally, left to right.
Each new line of 7 goes underneath the last line of 7 recorded.

When you see that you have recorded 4 dozen results in a row that do not match with the 4 dozen results on the line recorded above then that is the SIGNAL to start betting FOR a vertical MATCH to occur.

For example:

3121
2313

Here you have 4 dozen results that do not match the dozen results immediately above on the previous line. This is a trigger to bet for the MATCH in the next column on the current line. (or the first column of the next line if a line of 7 results is already complete)

Use the following Betting Line:

1,1,1,2,2,2,3,3,3,4,4,4........etc

Forward 1 on a loss; back 2 on a win
**However - Reset to 1st 1 anytime when level or ahead**
