How teachers and streamers run it

Two real setups, start to finish. Each takes about a minute.

In a classroom

  1. Open the full wheel, paste the class list one name per line and save it as Period 1. Saved lists stay in this browser.
  2. Tick Remove after pick so nobody is called twice. Reset round puts every name back.
  3. Press Present for a full-screen wheel on the board. Space spins, Esc returns to the page.

Name picker for teachers: saved lists per class, big display mode and why a class list never leaves the device.

On a stream

  1. Build the wheel, press Copy share link, and swap /w# for /embed/wheel?theme=transparent#.
  2. In OBS add a Browser source with that URL at 600 by 600. The background stays transparent over your scene.
  3. Right-click the source, choose Interact, click the wheel once, then press Space to spin live.

Spin the wheel in OBS: URL parameters, sizes and what the overlay can and cannot do.

16 million test draws

Every draw uses your browser’s cryptographic random source with rejection sampling, so no slice gets a larger share. We publish the chi-squared results across 16 million draws with the code that produced them.

Class lists stay on this device

Nothing you type reaches a server. A shared wheel travels in the part of the link after the #, which browsers never send, so a class list exists only in the browsers that open it. No account, no cookie banner.

One line of HTML to embed

Put a wheel on WordPress, Google Sites, Notion, Moodle or Canvas with a single iframe. The embed guide has a copy-paste block for each of them.
