There are some many roulette players who play the game without knowing roulette odds or understanding the roulette odds and how they actually work. They probably know that if they correctly bet on a single number they will a massive payout, or if they got a win on a more general bet like on a color (red/black) or an odd/even number, they will get an even money payout from the casino. But not all roulette players know why or understand why.
So the word Roulette originates from France and its true translation means “small wheel”. The very first roulette wheel was invented by the French scientist Blaise Pascal in 1655. It was used in a monastery to help prevent boredom (I’m sure monasteries in those days weren’t fun places anyway). How it got into a Parisian casino from a monastery is another matter (another website) but it did find its way to Paris and became a glamorous casino game.
