Items and weights
The result is decided first with your browser’s cryptographically secure random generator, with exactly the chances set by the weights. The wheel is then turned to stop inside that item’s slice, so what you see always matches the result.
How to use
- Enter item names and weights (whole numbers 1–1,000). A bigger weight means a bigger chance and a bigger slice.
- Press "Spin". The wheel turns and the item it stops on is shown as the result.
- Optionally remove the winning item from the list or copy the history.
FAQ
Can the animation and the result disagree?
No. The result is decided first, by weight, with a cryptographically secure random generator. The rotation is then calculated so the wheel stops inside that item’s slice, away from its edges. Where it stops is the result.
How are the chances calculated?
Each item’s chance is its weight divided by the sum of all weights. With weights 1, 2, 4, 8 and 15 (sum 30) the chances are 3.33%, 6.67%, 13.33%, 26.67% and 50%. The slices use the same proportions.
Can I turn the animation off?
Yes. Tick "Skip the animation" or enable reduced motion on your device, and the result is shown at once without spinning.
