I like the concept of a 10-unit bankroll parachute to
compound the unit:
| Spin | Location | Bet amount | Loss + cost | Amount won | Total profit |
| 1 | Half | 1 | 1 | 2 | +1 |
| 2 | Dozen | 1 | 2 | 3 | +1 |
| 3 | Line | 1 | 3 | 6 | +3 |
| 4 | Line | 1 | 4 | 6 | +2 |
| 5 | Line | 1 | 5 | 6 | +1 |
| 6 | Corner | 1 | 6 | 9 | +3 |
| 7 | Corner | 1 | 7 | 9 | +2 |
| 8 | Corner | 1 | 8 | 9 | +1 |
| 9 | Street | 1 | 9 | 12 | +3 |
| 10 | Street | 1 | 10 | 12 | +2 |
There is no limit on wins. After a lost attack, you go back to the minimal unit bet.
The basic idea here is to concatenate positive runs of micro-games raising the bet unit in order to win the most on the positive trams, while going back to the minimal base unit for losing the least on the inevitable negative trams.
After every hit you take
50% of the net win and
re-invest it (add it) into the main/active attack bankroll. Dividing the new units / 10 to get the new bet amount.
It is advisable to play with an unit that is as divisible as possible in your roulette of choice. Ideally, it should be divisible / 10.
(This can also be considered as a 100-unit bank of minimal units)
Rounding down should be done for keeping the bets working on actual game conditions.
