Why SpinProof

A wheel your audience can actually trust

Most wheel spinners ask you to trust them. SpinProof shows its work, lets the room join in, and turns every spin into something you can share.

Verified results

The result is sealed on our server before the wheel moves. Afterwards anyone can repeat the maths on the proof page and see that nothing was changed.

About this wheel

SpinProof is a free wheel spinner for anything you need to pick at random: a student to answer, a giveaway winner, a restaurant, or who presents first at a meeting. Put each choice on its own line, press Spin, and the wheel stops on one of them.

What makes it different is the proof. Before the wheel moves, the result is sealed with a fingerprint and saved on our server. After the spin you get a link that shows the entries, the time it was locked and the maths behind the result, so anyone watching can confirm that nobody picked the winner by hand.

Classrooms

Pick who answers next, who reads aloud or which topic to review, in a way students see as fair.

Giveaways

Choose a winner from comments or entries and share the proof link with your followers.

Work

Decide who speaks first in a stand-up, who takes the next task or where the team eats.

Everyday choices

Settle what to cook, which film to watch or what to do this weekend.

Questions

Is the wheel really random?

Yes. The result comes from a 256-bit secret made by a cryptographic random number generator on our server. The secret is locked before the spin and revealed after it, and the proof page lets anyone repeat the calculation.

Is SpinProof free?

Yes. Every feature is free and you do not need an account. The site is paid for by ads, which never sit next to the Spin button.

How many entries can I add?

Up to 500 entries, each up to 80 characters long. Paste a list from a spreadsheet and each line becomes one entry.

Can I save my wheel and share it?

Press Share to get a short link to your wheel. You also get a private edit link, so only you can change it later.
