When to use a number wheel
A number wheel does the same job as a random number generator but makes the moment visible, which is exactly what you want in a classroom or on a stream. With the numbers 1 to 10 on the wheel, each has an exact 10% chance, decided by crypto.getRandomValues() before the wheel starts turning.
Switch to 1–20, 1–50 or 1–100 with one click. Up to 100 numbers stay readable on the wheel; beyond that, slices get thin, so for very large ranges our plain random number generator is the better fit. Turn on elimination to draw numbers without repeats, like a raffle or bingo caller.
Common uses include picking a student by register number, choosing which question to answer next, deciding how many push-ups to do, and assigning a random starting player. You can edit the list too — remove numbers you have used or add bonus slices like “Free choice”. Weights work as well: 7*2 makes seven twice as likely as any other number.
Frequently Asked Questions
Is every number on the wheel equally likely?↓
Yes. Each number has an equal slice and an equal chance — 10% each for 1 to 10. The winner is chosen with crypto.getRandomValues() using rejection sampling, so there is no modulo bias toward lower numbers.
Can I spin a number from 1 to 100?↓
Yes. Click the 1–100 button above the entries box to load all 100 numbers. Each then has a 1% chance. For ranges in the thousands, use the Random Number Generator instead, as wheel slices become too thin to read.
How do I stop the same number coming up twice?↓
Tick “Remove winner after spin”. Each number is removed from the wheel after it wins, so you can draw the whole range without repeats, and Undo restores the last number if you remove one by mistake.
