It is a simple system based on progression, suitable for those
who have at hand rather small or medium capital.
Bet on colors.
You start with one token and continue to bet one token,
until you lose twice in a row.
If this happens, the next time you bet two chips and continue to bet two chips until:
a) win twice in a row, while reducing the pledge of one token
b) lose twice in a row where the stakes increase of three tokens.
Progression looks like this: 1, 2, 3, 4, 5. If you get to the moment you bet 5 coins,
you can start again from one token or increase of 6, 8, 10, depending on your style of play and financial resources.
Remember only that bet increases after two consecutive losses, and decreased after two consecutive profits.
