Frequently Asked Questions

How is the random winner selected?

The wheel uses the browser's cryptographically secure Web Crypto API (`window.crypto.getRandomValues`) to generate random offsets, ensuring completely fair and unbiased spins.

How many names can I add to the wheel?

There is no strict limit, but for optimal visual clarity, adding between 2 and 50 names is recommended. Higher counts will result in narrower wheel slices that might truncate labels.

Can I use this for non-name options?

Yes! You can enter decisions, numbers, foods, colors, or any custom text options (one per line) to create a custom decision wheel.

Formula & methodology

Formula: Winner = names[⌊random() × n⌋]; wheel animates to the matching segment

The Name Picker / Wheel Spinner is built on a well-established calculation method. It uses the formula Winner = names[⌊random() × n⌋]; wheel animates to the matching segment to turn your inputs into a reliable result. A free random name picker and spinning wheel. Enter names, spin the wheel, and pick a random winner. Perfect for classroom activities, giveaways, and team decisions. The steps are shown on the page so you can follow the reasoning from input to output.

Enter one name per line — the wheel draws an equal segment for each.
Spin: a uniform random angle decides the winner; the canvas animation rolls to it with easing.
Spin again for the next pick, or remove winners between rounds.

Worked example: 8 names give each a 12.5% chance per spin; over many spins frequencies converge — streaks of the same winner are normal randomness, not bias.

Frequently asked questions

Is the wheel actually fair?

Yes — the winner is chosen by the underlying random draw: Winner = names[⌊random() × n⌋], where every entry has an equal 1-in-n chance. The wheel animation is visual only and always lands on the pre-drawn winner, so the physics of the spin never influences the outcome. With a cryptographically secure random source, every spin is independent and unbiased.

How many names can the wheel hold?

The Name Picker / Wheel Spinner is free, private, and accurate: it runs entirely in your browser (no uploads, no accounts), applies the standard calculation, and explains each step so you can verify the result. A free random name picker and spinning wheel. Enter names, spin the wheel, and pick a random winner. Perfect for classroom activities, giveaways, and team decisions. There is no limit on usage, and it works on any device.

Can the same person win twice?

Yes, by default — every spin is an independent random draw, so the same name can win consecutive spins, just like a real wheel. If you need unique winners (e.g., several prizes to different people), use the no-repeat mode, which removes each winner from the pool after the spin. The calculator offers both behaviors.

Can I use it for a giveaway?

Yes — paste the participants' names, spin once for the winner, and the secure random draw makes the result verifiably fair. For multiple prizes, switch to no-repeat mode so each person can win only once. Record the spin results if you need an audit trail. The wheel works for giveaways, team selection, classroom draws, and office decisions.

Why a wheel instead of a plain random pick?

The wheel adds ceremony and engagement — the visual spin builds anticipation and makes the outcome feel fair and transparent for an audience, which matters for giveaways, class activities, and team events. The underlying result is still the same secure random selection; the wheel simply makes the randomness visible and entertaining.
