Spin a fair choice wheel

Enter options, spin for a cryptographically chosen winner, share your wheel via URL, and optionally eliminate winners between rounds.

Wheel Spinner is a visual way to choose among a short list when a plain random number would be harder for a group to follow. Enter one option per line, remove duplicates as needed, and spin; the winning option is selected before the animation begins. Eliminate-winner mode supports several rounds, while a share link lets a co-host load the same configuration. Preferences and history stay local. The wheel is for casual decisions and events, not a certified drawing or proof of eligibility. Organisers use it for classroom picks, stream giveaways, and party games when a visible spin is easier to follow than a bare random number. The winning index is chosen with crypto.getRandomValues before animation, so reduced-motion mode only skips the spin presentation. Keep private names out of share URLs, and reset eliminate-winner mode when you start a new round of prizes. [batch-a-home-pass-2026-11-13]

Quick start

1. Enter one option per line—duplicates are removed automatically.
2. Press Spin. The winning slice is chosen before the animation starts.
3. Enable eliminate-winner mode to remove chosen options between spins.
4. Copy results, print, or share the URL so others load the same options.

When to use something else

• Classroom choice: Add activity names and spin to choose the next group task.
• Stream giveaway: Share the configured options with a co-host and eliminate each winner.

Limitations

• A share link contains the option list, so do not put private names or sensitive notes into it.

FAQ

Is the winner decided before the spin animates?

Yes. A cryptographic random index is chosen first; the animation (when motion is allowed) only presents that outcome. Reduced-motion mode skips the spin theater and still uses the same random draw so accessibility settings do not change fairness.

How does the shareable URL work?

Option lists can be encoded into the link hash so a host can reopen the same wheel on another device. Treat share links like a public whiteboard—omit private surnames, employee IDs, or anything you would not read aloud in the room.

What is eliminate-winner mode?

After a spin, the winning slice can be removed so the next spin draws from the remaining options. Reset the list when you start a new prize round so earlier winners are eligible again.

Can I spin with only two options?

Yes—two slices still get a fair 50/50 draw. For coin-style calls you can also use a dedicated coin flip tool; the wheel shines when you have many named choices to show on screen.
