Instead of doubling a bet after a loss the gambler doubles the bet after every win. The Reverse Martingale system, also known as the Paroli system, follows the idea of the martingale betting strategy, but reversed. Positive progression systems involve increasing the size of one’s bet when one wins. Regardless of the specific progression, no such strategy can statistically overcome the casino’s advantage, since the expected value of each allowed bet is negative. Another strategy is the Fibonacci system, where bets are calculated according to the Fibonacci sequence. A large financial loss is almost certain in the long term if the player continues to employ this strategy.

Announced (call) bets are multi-chip combinations that cover specific sections of the physical wheel. The single zero is not covered by any outside bet — when zero lands, all outside bets lose unless La Partage or En Prison is active. Every bet type has a specific payout ratio that never changes regardless of the casino, the variant, or how the wheel has been spinning. The games below run on virtual chips with no real money stakes.

There are 12 possible street bets on a European layout, plus the Trio bets involving zero. A €10 bet on a winning split returns €170 profit plus the €10 stake. This bet wins roughly once every 37 spins on average. Inside bets are placed on the number grid itself on specific numbers or the lines between them.
