*2 after an entry to double its chance. Pick an emoji or a picture, a title and wheel colours.Fair by design
Your browser picks the winner with cryptographic randomness before the wheel moves, and every slice is drawn to scale. Nothing is hidden, and nothing is decided on a server.
getRandomValues, in your browsercrypto.getRandomValues, the source browsers use for security keys, not the predictable Math.random.*2 gets twice the slice and exactly twice the chance. There are no hidden weights.From real classrooms
Three routines teachers run with a wheel every week.
Put your class list on the wheel and turn on “Remove the winner”, so every student is called once before anyone is called twice. The wheel picks, not you, which takes the sting out of being chosen.

Yes. Each spin uses your browser's cryptographic random number generator (crypto.getRandomValues) with rejection sampling, so every slice's chance matches its size exactly. The result is picked before the animation starts, and the wheel simply lands on it.
No. There are no hidden settings and no server deciding the result: everything runs in your browser, and every slice is drawn to its true size. If you want an entry to come up more often, give it a visible weight like *2, which makes its slice bigger for everyone to see.
Up to 1,000 entries. Paste a whole column from a spreadsheet; blank lines are skipped. With hundreds of entries the slices get thin and long names are shortened on the wheel, but every entry keeps its fair chance and the full name appears in the result.
Yes. Start any entry with an emoji, or use the emoji button next to an entry (in the Rows view) to pick one, choose a picture from your device or paste a picture link. Pictures from your device stay on your device: they aren't uploaded and aren't included in share links.
Add an asterisk and a number after the entry, like Pizza *3, or use the weight buttons in the list. That entry gets three times the slice and three times the chance. Weights from 1 to 99 work, and the slice size always shows the real odds.
Your list stays in your browser and is never sent to our server unless you sign in and choose to save it. A share link carries the names inside the link itself, so only share it with people who should see them. Students never need an account.
Use Share to copy a link with your entries inside it; it never expires and needs no account. The embed code puts the wheel on Google Sites, Canvas or Schoology. To keep wheels and class lists across devices, create a free account (adults 18+); Pro makes cloud saves unlimited.
Your wheel already lives in this tab and in its share link. A free account (for adults 18+) keeps wheels and class lists across devices. Pro ($3.99 a month or $29 a year) makes cloud saves unlimited, removes ads and adds your logo.
