Anti-martingale Roulette System
As the name of this Roulette system indicates, Anti-martingale is a betting system derived from its more famous colleague Martingale. The strategy is applied in the opposite way.
The Principle of the Anti-martigale System
The principle of the system again consists in doubling the bets – not after each losing spin as in case of Martingale, but after a winning spin. Therefore Anti-martingale is a kind of the sequel bet. The win (and the risk) depends on the length of the sequel, which you set in advance.
Even odds with the payout ratio of 1:1 are used again (Low/High, Red/Black, Even/Odd numbers). For instance you can decide to bet on the red colour five times in a row. Or you can bet alternately on the red and black numbers, or on any other combination of even odds (1:1).
How to Use the Anti-martingale Strategy
Make a bet of one unit on the first bet of your sequel. If you win, leave you win including your initial bet on the table (or place/move on the next bet in your sequel), so you raise your initial bet by the achieved win. Keep betting in such way until you finish your sequel. That means you bet 1, 2, 4, 8, 16, 32, 64, 128... units consequently.
| Number of Spins (Length of the Sequel) | Win in units | Chance of Winning the Whole Sequel (%) |
|---|---|---|
| 1 | 1 | 48.65% |
| 2 | 2 | 23.67% |
| 3 | 4 | 11.51% |
| 4 | 8 | 5.60% |
| 5 | 16 | 2.72% |
| 6 | 32 | 1.33% |
| 7 | 64 | 0.64% |
| 8 | 128 | 0.31% |
| 9 | 256 | 0.15% |
| 10 | 512 | 0.07% |
Please note that the probabilities in the table above apply to the French Roulette. The winning chance in American Roulette is lower due to the presence of the double zero.
Comments on the Winning Chances of the Anti-martingale System
Let us say that you bet on the above-mentioned sequel of 5 spins. The probability to win the whole sequel
is 2.72% only. This is because it deals with the consequent events, whereas
you have got 18 winning possibilities out of the total of 37 (there are 36 regular numbers plus zero in roulette).
The probability to win the whole sequel (5 spins in a row) is then (18/37)5).
The initial one unit would grow your capital to 16 units, though the house edge is 6.4%.
Evaluation of the Anti-martingale System
Despite it is not easy to finish the sequel, especially a long one, the good thing is that every time you lose (thus not finishing the sequel), it costs you only the one initial unit.
