FAQ

Spin a fair choice wheel — quick answers about privacy, fairness, and limits.

Using the tool

Is the winner decided before the spin animates?

Yes. selectWinnerIndex runs first with crypto.getRandomValues; animation is presentation only.

How does shareable URL work?

Your option list is encoded in the query string. Opening that link pre-fills the wheel on another device.

What is eliminate-winner mode?

After each spin, the winning option is removed so it cannot be picked again until you reset.

Can I spin with only two options?

Yes. The wheel works with any number of unique options from one upward.

Does reduced motion affect fairness?

No. It only skips the rotation animation and shows the winner immediately.

Is history stored?

Recent spin results are saved in localStorage on this browser.

Are colors assigned automatically?

Yes. Each option receives a distinct palette color for readable slices.
