Spin the wheel

How it works

A spinning wheel is a random picker that people can watch, which is why it is used for classroom draws, team decisions and giveaways. The watching is the point: everyone sees the same thing happen.

The result is decided before the wheel turns

The winner is chosen using the browser's cryptographic random source the instant you press spin, and the animation is then played to land on it. That may sound backwards, but it is the honest way round: an animation that decided the outcome from where it happened to stop would be biased by friction and timing.

Every entry has an equal chance

The range mapping discards values that would make some entries very slightly more likely than others, so the draw is genuinely uniform. Adding the same name twice gives it two segments and twice the chance, which is the usual way to weight a draw deliberately.

Running a series of draws

After a spin, the winner can be removed with one button so the next draw excludes them. That is what you want for prizes in order, or for picking an order of play.

Nothing is recorded

The entries and the result exist only in your browser. Nobody else can see who was on the wheel or who won, and the draw cannot be reproduced afterwards — record it yourself if you need to show it happened.
