Roulette Wheel Rotation Period Variation for Prediction Prevention

The patent applies dynamics by making the rotation period of the roulette wheel variable rather than fixed. The rotation period is determined randomly for each game, causing the wheel to rotate at different speeds and for different durations across games. This dynamic adjustment prevents players from predicting winning numbers while the control process remains simple because it only requires setting a random period parameter without complex speed control mechanisms.

The patent applies parameter changes by varying only the rotation period parameter while maintaining a constant rotation speed. This approach achieves predictability prevention through random parameter selection without requiring complex drive control processes. The simplicity is maintained because the system only needs to set a random time period value, avoiding the complexity of dynamically adjusting motor speed during rotation.

The patent applies the taking out principle by extracting only the essential element needed for randomness - the rotation period - while removing the complex system of varying rotation speed based on pseudo-random numbers. By using a simple random period selection without complex random number generation circuits and speed variation mechanisms, the patent achieves predictability prevention with minimal device complexity.
