I have been working on this system for a long time now (partly the reason I have been inactive in the forum), and I am happy to announce that it works extremely well, and if some defenses are incorporated into this system it's bulletproof from losing.
It's extremely simple and triggers come fast. It also an extension of the law of 2/3s.
The system has been tested on paper with real spins from Wiesbaden and also in a real casino, and I can't get it to lose.
The trigger is in the form of XXY. (XX are 2 numbers in the same dozen and Y is another dozen).
Needless to say that XYX and YXX is the same thing as far as the trigger is concerned.
When we see this trigger in the last 3 numbers spun we simply bet the single dozen (Y), for 3 bets
However 4 bets is fine too if the minimum is low enough.
22,17,35. We bet the 3rd dozen
4,11,13. We bet the 2nd dozen.
25,3,31. We bet the 1st dozen.
I tested it by betting only 3 times. If it fails, in all 3 bets in the cycle, I wait for a new trigger. Betting 4 times is not wrong. it's a personal choice
The progression in units can be 1-1-1.5 or 1-1-2 if you like.
If the entire 3 bet cycle fails, you start the new trigger with a slightly higher chip. ( No need to go Martingale for obvious reasons).
Situations where you avoid betting, and wait for things to become more normal
1. If the same dozen appears repeatedly immediately preceding the trigger. (it's a sign of anomaly that can affect the rest of the dozens).
2. If the playable target dozen ( Y), has appeared more than 3+ times immediately prior to the trigger. (meaning it has appeared enough times already and runs the risk to disappear when you begin betting it 3 times after the trigger).
3. If the first 2 bets after the trigger result in XX (same dozen as the majority dozen in the trigger, you stop and only lose 2 bets). Easily recoverable in the next trigger
4. if there is more than one 0 in the numbers preceding the trigger. (0's tend to come in packs).
I have made a special point to pay attention to consecutive (back to back ), trigger losses and they simply don't happen.
Sometimes you will get 2 back to back trigger losses, but it's rare.
3 back to back trigger losses is extremely rare, and I have not seen 4 + consecutive trigger losses yet.
And I have tested many numbers.
In the picture I have a sample test:
I circle the trigger (XXY) with blue, and when it wins within the 3 playable spins I put a check mark on the number that won.
When it losses, I put 3 red X's indicating that the 3 spins lost.
As you can see it won 25 times and lost 5 times for 3 spins each time.
But provided that the next trigger after a lost trigger has won, it's obvious that the loss was recovered and if the progression is higher you end up with a profit too. Which means the entire session was a win
The only way you could lose would be if many back to back triggers fail. Like 4+ and if they happen frequently.
But this is not happening in this system. A good B/R can handle a trigger loss here and there, or even 2-3 back to back trigger losses. Which are of course rare.
Any player can handle a 3 steps cycle loss of a single dozen , as it compares to playing 18 and 24 numbers.
This system can be played "hit and run" style, as you can observe several roulettes for a trigger.
By the way the system applies to COLUMNS too.
And sometimes if you combine dozen and column trigger simultaneously, you can bet the 4 numbers that belong to the same dozen and column at the same time
