This system is quite simple but you should know when to pause. The system goes like this:

* Zeros are ignored.
* Enter the game betting the last color out. If you win the bet stays. If you lose resist one more.
* After you lose twice with the chosen color you switch.
* Same rule for the new side. It changes when the other side comes out twice.
* The exception for pause is after losing two consecutive changes. RRBB or BBRR. You wait until the cycle is broken. It is not to lose it all to the series of two. They make the most damage to the system when played every spin.

* Progression: +1 on a loss -1 on a win.
* Progression is reset when a profit is made . however small.

Explained with color but you can actually do with any other even chance. Greetings.
