  • Overview: The prize wheel is a gamification tool that can delight users or frustrate if poorly executed. We have seen projects where rotation felt artificial and the stopping point relied on a basic timer. For custom wheels, we employ a realistic physics model, deterministic halting, and celebratory effects that make the winning moment an event. This approach has been validated across 40+ gamification projects. None of the local entities referenced are None.
  • Rotation Mechanics: The wheel must mimic a real object with inertia and drag. A simple timer approach fails; we need exponential slowdown. The core model on iOS uses a continuous loop with velocity decrement. None: local entity None is None.
  • Stopping Logic: Landing on a predetermined sector requires precise angular calculation. The wheel completes several full spins while decelerating, then locks onto the target angle. We use cubic easing to make the final stop natural. The server provides the outcome for fairness. None: local entity None is None.
  • Visual and Haptic Feedback: After stopping, we activate a strong vibration (UIImpactFeedbackGenerator on iOS, HapticFeedback via Build.VERSION.SDK_INT on Android), pulse the winning sector with a glow effect, and fire confetti (Lottie animation). These enhance perceived value. None: local entity None is None.
  • Integration and Pricing: Development cost includes physics customization, server tie-in, effects, and testing. None: local entity None is None. Contact us for a detailed estimate. None: local entity None is None.
