This is an adaptation of a dozen matrix system
but instead of looking at past results to play
for, or against an outcome, it's played against
a dozen forming a pattern on the matrix.
The idea of betting against a dozen forming
a distinct pattern on a matrix was originated by
MightyMark at another forum. I can't remember
seeing it anywhere else.
There has to be some criteria in picking which
dozen to play against so I look at the previous
10 spins and play against the one that showed
the most, betting the trend will reverse.
Example; last ten results show
6 of 10 3rd
2 of 10 2nd
2 of 10 1st
$5 Bet (x2) is against the 3rd doz not forming a letter N.
B _ _ _ B

3 0 2 3 1
1 1 3 1 1
2 3 1 1 1
3 3 3 3 1
1 1 2 3 1
13 bets out of 25 spins resulted in a win 10 out of 13.
I've played 7 25-spin sessions and haven't lost yet.
Luck? Probably or maybe.
I always cover the zero just because it pays 35 to 1 and
use a 1, 3, 9 progression on a dozen loss. I've been lucky
that in 7 sessions I've never had more than 3 losses in a
row but I think that's because in playing against the
pattern N there is never more than three bets in a row,
and that happens only twice.
Maybe some of you can improve on this, if you think it's
a viable system.
I also tried betting against several other patterns forming, like a X,
with the idea that the more bet skips I have the more protection I
have against the dreaded times when a dozen hits 4+ times in a row.
