Random Wheel
how we choose
Fair pick with crypto.getRandomValues The winner is chosen before the wheel moves, with your browser’s cryptographic random generator (crypto.getRandomValues) and no bias toward any position. The animation only lands on that result. With weights on, each entry’s chance is its weight divided by the total.
Type your options, one per line, and spin. Every option gets the same slice, and the result is drawn before the wheel starts moving.
What makes this wheel random
Each spin takes a number from crypto.getRandomValues in your browser and maps it to a slice. The animation only shows the result; speed, timing and where you tap do not change it.
All slices are equal unless you turn on weights, so with five options each one has exactly a one in five chance. The result card shows that chance, so anyone watching can check it.
Draw without repeats
Choose Remove and spin to take the winner off the wheel. Keep going and every option comes up once, in a random order: handy for turn order, presentations or a raffle with several prizes.

How many options can I add?
Up to 500 entries. Long lists work best with Remove and spin.

Yes. There is no sign-up, and your wheels stay saved in this browser.
