Can you guess roulette number by eye?

It is highly unlikely to guess the roulette number by eye, as the spinning of the ball and the wheel is a highly random process. The outcome of each spin is determined by the laws of physics and chance, and there are numerous factors that can affect where the ball will ultimately land, such as the speed of the wheel, the speed and direction of the ball, the angle and trajectory of the ball, and any imperfections or irregularities on the wheel or ball.

While some experienced roulette players may be able to make educated guesses about where the ball might land based on their observations of the wheel and ball movements, there is no reliable or proven way to consistently predict the outcome of a roulette spin with any degree of accuracy. In short, the game of roulette is designed to be unpredictable and random, and any attempts to predict the outcome through visual cues or other means are unlikely to be successful.
