Why do roulette wheels have to spin?

Roulette wheels are designed to spin in order to ensure that the outcome of each spin is random and unbiased. When the ball is spun around the roulette wheel, it bounces and lands on a randomly selected slot, which determines the winning number or color for that spin.

The spinning motion of the roulette wheel is also an important part of the game's atmosphere and excitement. The anticipation and suspense of waiting for the ball to land on a winning slot is a key part of the roulette experience and is one of the reasons why the game has remained popular for centuries.

In addition, the spinning motion of the roulette wheel helps to prevent cheating and tampering with the game. If the ball and wheel were stationary, players could potentially manipulate the outcome by influencing the ball's placement or interfering with the wheel.

Overall, the spinning of the roulette wheel is an essential part of the game's mechanics and adds to its excitement and fairness.
