Wheel Spinner

A wheel spinner provides a visually engaging way to make random selections — useful when decisions need to feel fair and transparent. Unlike drawing names from a hat, a spinning wheel lets everyone see the process and result in real-time. The randomization uses crypto.getRandomValues(), the same cryptographically secure random number generator used in security applications, ensuring truly unpredictable outcomes. You can add any number of entries (names, options, prizes, tasks) and optionally assign different weights to each segment. Equal weighting means each option has the same probability — 6 entries each have a 16.67% chance. Custom weights allow adjustments: a prize wheel might have a grand prize at 5% probability, medium prizes at 15% each, and consolation prizes filling the remainder. After each spin, you can optionally remove the selected entry to prevent repeats (useful for door prizes or assigning unique tasks). The physics simulation includes realistic deceleration and randomized stopping positions. All processing runs locally — no entries or results are transmitted anywhere.

Beyond simple decision-making, wheel spinners serve surprisingly diverse purposes. Teachers use them for cold-calling students fairly (every student knows they might be called, increasing engagement), assigning group projects, or choosing discussion topics. Families use them to settle dinner choices, assign chores, or pick movie night selections — removing the negotiation that slows down group decisions. Content creators and streamers use prize wheels for audience engagement: viewers suggest entries, and spinning the wheel creates suspense and entertainment. Team managers use them for meeting facilitators, sprint retrospective topics, or team lunch choices. Party games benefit from spinner integration: truth-or-dare with random selection, Secret Santa assignments, or choosing who goes next. Marketing events use custom prize wheels for booth engagement — visitors spin to win discounts, swag, or free trials, creating a memorable interaction. For D&D and tabletop gaming groups, spinners add visual flair to random encounters or loot distribution. Create themed wheels with colors matching your brand or event for a polished presentation.
