Prize Wheel
A giveaway wheel where the grand prize is rare. Each slice's size shows its real chance.
Prize wheel
One entry per line. Add “*3” after an entry to make it three times as likely. Up to 500 entries.
Weighted entries get bigger slices. Slice size equals the chance of winning.
Ways to use this wheel
- Set the stock you have as weights so common prizes win more.
- Run Test fairness in Settings to show the odds to your audience.
- For a list of entrants, use Name Picker with a provable draw.
Questions
Are the odds really the slice sizes?
Yes. Slice size and chance are computed from the same weights, and the winner is drawn exactly in proportion.
Can I prove the draw was not rigged?
For winners chosen from a list, Name Picker's provable draw publishes a fingerprint first and lets anyone check it later on the Verify page.
Is the wheel really random?
Yes. Before the wheel moves, the winner is drawn with your browser's cryptographic random number generator (crypto.getRandomValues), using an exact weighted draw. The animation then lands inside that slice, so what you see is what was drawn.
How do weights work?
An entry with weight 3 is three times as likely as an entry with weight 1, and its slice is three times as wide. Weights can be decimals, like 0.5 for a rare prize.
