Roulette is an EV- game, so you cannot beat the house, the only way to win is to stole coin when dealer is not looking (Einstein)

Personne ne peut gagner à la roulette à moins qu’il ne vole l’argent de la table lorsque le croupier ne regarde pas.

-- Albert Einstein

RNG

Thanks to skeeto, he found an issue with the number generator with attempt at rejection sampling and proposed a fixed I implemented. Number seems now more uniformly distributed as you can see:

I'm aware this is a toy RNG and the purpose is not to replicate a true RNG which can be quiet hard without dedicated hardware.
