How to use it
- Type one option per line in the box. The wheel redraws as you type.
- Press Spin. After about four seconds the pointer at the top lands on the winner.
- Every result is logged under the wheel. Use Copy share link to send the same wheel to a group chat.
How the random pick works
With n options the tool needs a whole number from 0 to n−1. It draws a 32-bit value from crypto.getRandomValues, the same source browsers use for security keys. Simply taking that value modulo n would make some slices very slightly more likely, so values from the uneven tail are thrown away and redrawn (rejection sampling). Only after the winner is fixed does the wheel calculate how far to turn.
Ideas
Friday lunch
Pizza, tacos, sushi, burgers, salad, pasta. Spin once and stop arguing. If the group vetoes the result, remove it and spin again — the history shows what came up.
Cold-calling in class
Paste the class roster, switch on winner removal, and spin whenever you need a volunteer. Students can see the pick is random, which keeps it from feeling personal.
Giveaway on a stream
Add the entrants, share your screen and spin live. Copy the history afterwards so you have a record of the draw.
Limitations
- Lists are not saved between visits. Keep the share link if you want to reuse a wheel.
- For prize draws with legal rules (sweepstakes, raffles), check what your local regulations require for documenting the draw.
