Even 4x3 Matrix Breaker

[userpairs]

Ok, firstly, I haven't tested this system much, that's why I put it into "The Notepad" forum.

The rules:
Write down all 3 even chances 4 spins wide matrixes - H/L, R/B and O/E. Like this:
HHLH          RBRB           OOOE
LHHL          RBBR            EEEE
LLHH          BBRB            EOOE
...

When you do this, look for full vertical repeatings. For example:
HHHH
LHHL
LHHL

Now you have to place your bets against third exact pattern forming. Basically we bet that Random will not make precise 4x3 matrix. I checked some real spins from Unibet roulette and patters from Random.org and these precise patterns is soo rare that I found only 2 of them in maybe 1000 spins, but triggers is frequent, so you'll don't have to track numbers for hours to make 1 unit profit.

Additional playing rules:
1. Play until you win 3 times, then close roulette window and chill for hour (Hit'n'run).
2. Use 1,2,4,8 progression (15 units risk).
3. If you lose, try to recover half of your loss with 7,14,28,56 progression (maybe better way is to wait for virtual loss and then use 7,14,28 progression to reduce the risk).

Maybe there is better progressions to play with - leave your suggestions here.

By the way, my first test game was a loss and I was like  .

Good luck!
