Roulette is a game of chance, and it is not possible to predict with certainty what number the ball will land on. The outcome of each spin is determined by a random number generator, and the odds of winning are the same on every spin.
Roulette tables in licensed and regulated casinos do not have magnets. Using magnets or any other tampering mechanism would be illegal and fraudulent. Casinos are required to adhere to stringent regulations enforced by gaming authorities to ensure fairness and compliance with the law.
