Pro Tips & Best Practices

True Mathematical Fairness via CSPRNG

Unlike amateur wheels using Math.random(), our wheel utilizes window.crypto.getRandomValues, ensuring hardware-entropy cryptographically unbiased outcomes for prize raffles.

Use Weighted Slices for Tiered Giveaways

If common prizes should appear more frequently than rare prizes, assign weights (e.g. 5x vs 1x) rather than typing duplicate entries manually.

Enable Full-Screen for Livestreams and Classrooms

Press F11 or click Full-Screen mode to hide all browser chrome and controls for professional projector presentations.

Common Gotchas & Troubleshooting

⚠️Sound Effects Not Playing

Modern browsers block audio autoplay until the user first clicks on the page. Click anywhere on the wheel canvas to initialize the Web Audio API synthesizer.

⚠️Too Many Slices Crowding Text

When using more than 30 slices, text labels automatically taper to concentric radial lines to maintain visual readability.

Frequently Asked Questions

Is this wheel picker truly random and fair?▼

Yes. The stopping angle is selected using the browser's cryptographic randomness API (CSPRNG), which samples operating system hardware entropy. Every slice has an exact mathematical probability proportional to its assigned weight.

Can I remove an option after it is selected?▼

Yes. Enable the 'Eliminate winner after spin' toggle. Once an option is chosen, it is automatically removed from subsequent spins, ideal for raffle draws.

How many choices can I put on the wheel?▼

You can add from 2 up to 500 choices. The canvas automatically subdivides angular arcs to accommodate large participant rosters.

Is this tool free and private?▼

Yes. 100% client-side execution. Your participant lists and contest outcomes are never transmitted to external servers.
