Did you know, there was originally no zero on the roulette reel? Sometimes around 1930 was in Monaco a bizarre invention introduced and that was the strange green zero field. The players were not aware about what actually happened. The zero is just one extra field but leans the odds on the side of the casino just a little bit – less than 3% to be precise, but that was enough.
Since this “improvement” went the odds from around 50% to 53% to the side of a casino and their incomes jumped up dramatically. Not is if before this invention it was called the French Roulette, but the single zero is the key difference between the casino game American Roulette with 2 zeros.
