What are the frets in roulette?

[Julio88]

The frets on a roulette wheel are the diamond-shaped separators that are placed between the pockets on the wheel. These separators help to keep the ball moving in a random and unpredictable pattern as it spins around the wheel. Frets can become loose or damaged over time as a result of mishandling during wheel maintenance,which can affect the spin and reduce the randomness of the ball's movement., thus shifting it towards a biased one.

The ball is stabilized by the frets as it rotates the wheel. Without the dividers, it could be more difficult to identify the winning number because the ball might juggle or jump between pockets. By preventing the ball from skipping or rolling too irregularly, the frets aid in maintaining a more predictable path.
