Random Wheel
This random wheel shows each entry's chance next to it, so you can see the spin is fair. With 8 equal entries, each one has a 1 in 8 (12.5%) chance on every spin.
Entries
8One entry per line. Paste a whole list — up to 1,000.
How to use the random wheel
- 1List your options: One option per line. The odds column updates as you type.
- 2Check the odds: Each entry shows its chance. Equal slices mean equal odds.
- 3Spin: Press SPIN. The winner is picked first with secure randomness, then the wheel animates to it.
How the random wheel picks
The winner is chosen before the wheel moves, using crypto.getRandomValues — the same randomness browsers use for security. The animation only shows the result; how hard or long it spins doesn't change who wins.
Each spin is independent. If Option 3 won last time, it has exactly the same chance next time. Turn on "Remove the winner" if you don't want repeats.

Short answers
Can I make one option more likely?
Yes, two ways. Free: add the same entry more than once — 2 of 8 slices gives it a 25% chance. Pro: set a weight on the entry and the slice grows to match.
Does a longer spin change the result?
No. The winner is picked before the animation starts. Spin time only changes how long the wheel turns.
Is a random wheel the same as a random number generator?
Under the hood, yes: the wheel draws a secure random number and maps it to a slice. The wheel just makes the result visible to everyone.
