Spin the Wheel — Random Wheel Spinner

A spinning wheel is the fairest-looking way to choose: what to eat, who presents first, which prize a raffle ticket wins, or which forfeit a party game hands out. This wheel draws the result first with your browser's secure random number generator and only then animates the spin, so every entry gets exactly its share of the wheel. Add a weight to give some entries more slices, remove winners as you go, or use a seed when you need to prove a draw can be repeated.

How to use this tool

1. Type or paste the entries, one per line. Add *2, *3 … after an entry to give it two or three times the chance.
2. Choose how many spins to make and whether each winner leaves the wheel.
3. Optionally pick colours and a seed, then press the button to spin.
4. Copy the winner, the spin history or the entries that are left for the next round.

Formula

P(entry) = weight of the entry ÷ sum of all weights

Each spin draws one integer from 0 to (sum of weights − 1) with rejection sampling, which removes the small bias a plain remainder would add. The integer falls inside exactly one entry's range of tickets; the wheel then rotates five full turns plus the angle that brings that slice under the pointer.

Example

With Pizza*3, Tacos, Sushi there are 3 + 1 + 1 = 5 tickets, so Pizza covers 3/5 of the wheel (216°) and wins 60% of spins, while Tacos and Sushi each have 20%. With “remove each winner” on and three spins, you get a full random order of the three options.
