This betting strategy is only work in european roulette with single zero and will not work in American roulette with double zero. This roulette strategy is tested working in online roulette from above mentioned gaming sites.

Using my own 1/9 bet system with D'alembert combination. Works well if you preset a budget to profit ratio by $250/$500. Risk is $500 max, and winning of $250 is achieved in 5 minutes.

Do not set to risk profit ratio too high, or the system will failed. In good or average hand, the system will help you to win in both scenario. Unless you are hitting lots of loses, and the max you will lose is $500. Follow the rules and the strategy will works.

The calculation is 4/37, or 0.1081. That is about 1 winning in every 9 games. This is forward system and the counter could be growing faster than it should be. That also mean the account balance will recover quickly and the loses can be recovered soonest possible. This strategy works for good hand and it can make better win over time. Player can choose to reset the counter whenever their new balance is higher than previous high, or choose to reset counter when a certain profit is hit.
