Roulette wheel goes back to Blaise Pascal. According to the history he was the one who invented the roulette wheel while attempting to create a perpetual motion machine. Time went by and the wheel was improved to be as we currently know it.
It is a meticulously crafted rotating wheel that is fixed to the roulette table. Numbers ranging from 1 to 36 alternate between small and big, black and red, even and odd. The wheel also has an extra slot of 0 and 00 (00 in American roulette). The wheel has unique pockets adjacent the numbers where the ball ends randomly.
The wheel is crafted to place all the red and black, even and odd, small and large numbers evenly on the wheel. The design is a standard in each casino. Dealer spins the wheel in one direction and rolls the ivory ball in the opposite direction. The ball ends up slowing down until it ends on one of the numbered pockets on the wheel.
