Spin the Wheel
Type or paste a list, spin, and let the wheel decide. Weights, colours, elimination and tallies are built in.
One entry per line. Add “*3” after an entry to make it three times as likely. Up to 500 entries.
How to use it
- Type your entries in the box, one per line, or paste a whole column from a spreadsheet.
- Want one entry to win more often? Write “*2” or “*3” after it, or use Weights & colours.
- Press Spin, click the centre of the wheel, or press Space.
- Remove the winner for the next round, or set After a win to Tally to keep score.
- Share the wheel as a link, or press Present to fill the screen in a classroom or meeting.
Where people use it
Classrooms
Put the class list on the wheel, set After a win to Remove, and every student gets one turn before anyone gets two.
Team decisions
Lunch, the next presenter, who writes the notes. Spin it on the shared screen so nobody argues with the result.
Streams and giveaways
Weighted prize wheels show the real odds as slice sizes. Run 10,000 test spins to show your audience the numbers.
Questions
Is the wheel really random?
Yes. Before the wheel moves, the winner is drawn with your browser's cryptographic random number generator (crypto.getRandomValues), using an exact weighted draw. The animation then lands inside that slice, so what you see is what was drawn.
How do weights work?
An entry with weight 3 is three times as likely as an entry with weight 1, and its slice is three times as wide. Weights can be decimals, like 0.5 for a rare prize.
Are my entries uploaded anywhere?
No. The list is saved in your browser's local storage. If you share a link, the list travels inside the link after the # sign, which browsers do not send to servers.
How many entries can a wheel hold?
Up to 500. Labels on very thin slices are hidden so the wheel stays readable, but every entry can still win.
Can I use it full screen on a projector?
Press Present. On phones that do not support full screen, the wheel fills the browser window instead. Press Escape or Exit to leave.
