Initially, there were only 28 sections on the American roulette wheel. In 1886, zero and a double zero appears here. It gives the second name to the game as roulette with a double zero. Over time, the number of sections on the roulette wheel has increased up to 38, it has retained zero and double-zero, and this fact, by the way, increases the house edge of the casino.
Betting Systems for American Roulette
All the betting systems for American roulette can be divided into the progressive and non-progressive. In progressive betting systems, the size of the next bet depends on the outcome of the previous round, while in non-progressive betting systems, the size of the bet is fixed and independent. All the progressive system can also be divided into 2 groups. Depending on the outcome of the previous round, the next bet is raised or lowered, that is, the betting system may be with a positive progression, insuring system, or with a negative progression.
Betting Systems with Positive Progression
Martingale Betting System. This simple betting system with a positive progression allows you to return the lost bet if the next bet wins. If we bet $1 and lose then, the next bet is $2. The main disadvantage of this betting system is that with a limited budget, we will quickly consume all the money if a string of losses lingers.
Parlay Betting System. Unlike the Martingale system, we increase the bet twice after winning, not losing. Here, we are not limited by the bankroll size as in the Martingale system, we make a fixed-sum bet and risk only with the previous win.
Paroli Betting System. According to this betting system, we do not change the bet in case of a loss, but we double the bet after winning. Using this betting system, we risk only the won amounts, but we do not win very much either.
D'Alembert Betting System. It is very similar to Martingale Betting System, where you should increase the bet after the loss. Insuring betting systems must compensate losses so they reduce bets after winning. D'Alembert Betting System uses this principle. The next bet is changed according to the previous round outcome. If your previous bet wins, you decrease the next bet, if you lose, you increase the next bet.
Betting Systems with Negative Progression
Betting systems with negative progression are such betting systems, when the next bet increases after losing. Such systems are used for external bets (red or black, even or odd). The main disadvantage of such betting systems that you lose your whole bankroll fast if the losing streak is long enough.
The Best Betting System
Roulette is the Wheel of Fortune and there is no betting system that is 100% likely to win. At roulette, the casino always has an advantage over the players, and this is zero on the roulette wheel. In American roulette, there are two zeroes, which doubles the advantage of the gambling house.
