How often do players really win cash?
In contrast to blackjack or poker, roulette really is a luck-based game. So how often players win is truly dependant on Lady Luck. However, there are numerous betting strategies that try and bend the odds in your favor, but how effective they are is still a matter of debate.
Your odds also depends on the type of roulette that you’re playing. American roulette, which adds a double zero in addition to a regular zero, doubles the house edge. Your best bet would be no-zero roulette, but those are incredibly difficult to find.
