The name of this system says it all. It is similar to the Paroli system. It is based on the premise that you can win four times in a row.

Your initial bet is 1 unit, the second 3 units, the third 2 units and the fourth 6 units. Let's assume that each unit is $10 and the odds are 1:1 - even money.

The first bet is $10. When winning, $10 is added to the $20 on the table making the second bet $30. When winning again on the second bet, there would be $60 on the table. Of this you take down $40 and the third bet is now $20. If the third bet wins, you will have $40 on the table to which you add $20 making a total of $60 for the fourth bet.

If the fourth bet wins, there would be a total of $120, of which $100 is net profit. Now all the bet with the profit is taken down and you start the system all over again at $10.

If you lose the first bet, your loss is $10. The second level loss is $20. At the third level, a loss will give you a net profit of $20. At the fourth level, a loss leaves you breaking even. Each time you lose, you start all over again at $10.

The attraction of this system is that you risk $20 at a chance of making $100 net profit. This means you can lose five times, and with one win get your money back.
