Temperature changes can affect roulette wheel behavior by impacting the materials of the wheel and ball, potentially altering friction and bounce characteristics. When temperatures rise, materials may expand slightly, which can change how smoothly the wheel spins and how the ball interacts with pockets. Conversely, colder temperatures might make materials contract or harden, affecting the ball’s bounce and trajectory. These subtle shifts can impact randomness by introducing minor biases, making regular environmental control and maintenance important for ensuring consistent and fair outcomes.
