I am playing those free spins quite aggressively and it worked good first time when I walked with 55$, not so good second time, I got just 3.5$. I am playing on Voisins Du Zero, and doubling tripling my stake any when it does not land
For those of you who don't know that is a bet that covers 17 numbers (46% of the wheel) centered around 0. You have to bet at least 9 units cover this spread.
But the probability of three unrelated events repeating is equal to the multiplication of the probabilities of their occurrence, right? So (1/37)3=1/50653
The first time I played non-aggressively (martingale on white-red), and the second time, for reasons beyond my control, I made a mistake and received only $ 4.40, which I immediately lost But I immediately decided to win back with my money and succeeded in this (however, I am unhappy because it was an emotional decision).
