A spin wheel is only meaningful when the entries, weights, duplicate policy, and selection method are clear before the spin. Review the complete list, remove accidental duplicates, and decide whether selected entries remain eligible. Visual segment sizes should match actual probabilities; animation duration and pointer position must not imply a different result. For consequential selections, keep an auditable record and use an appropriate independent method. Do not use an entertainment wheel for regulated gambling, security decisions, or high-stakes allocation.
