How Wheel Spinner works
How does the wheel spinner work?
The wheel is drawn on an HTML5 <canvas> with one colored slice per option, and spinning adds a random rotation of 5-8 full turns plus a random offset (via Math.random()) to the wheel's current angle. After a 4-second CSS transition, the tool works out which slice ended up under the fixed pointer at the top and reports it as the winner.
When would I use this?
It's built for picking a random winner from a list - deciding who picks the restaurant, choosing a raffle entry, or randomly assigning tasks among a small group. You can add or remove options freely, as long as at least two remain for the wheel to spin.
Is the spin result truly unpredictable, and can I change the odds?
Every slice is the same size, so with equal option counts each entry has an equal chance of winning - but since it uses Math.random() rather than a cryptographic source, it's not suitable for anything requiring provable fairness. There's no built-in way to weight one option more heavily than another; the only way to shift the odds is to add the same entry to the list more than once.
