How to use the number wheel
Type a minimum and maximum, or tap one of the quick ranges: 1–10, 1–20, 1–50 or 1–100. Then press Spin, tap the wheel, or press Space. When the wheel stops, your number pops up in large type that's easy to read from the back of a room. Every pick is added to the history so nobody has to remember what came up.
Small ranges spin, big ranges roll
A wheel can only show so many slices before the numbers become too small to read. Up to 100 numbers, you get a full wheel with every number on it. For bigger ranges, like raffle tickets numbered 1 to 2,000, the page switches to a rolling counter that flickers through numbers before settling on the result. Negative numbers work too, so a range of -10 to 10 is fine.
No-repeat mode
Tick Don't repeat numbers and each number leaves the wheel once it has been picked. That's what you want for calling bingo, drawing raffle tickets one by one, or giving every student number a turn before anyone goes twice. The panel shows how many numbers are left, and clearing the history puts them all back.
Ideas for the classroom and game night
- Choosing who answers: give each student a number and spin 1–30 instead of picking the same raised hands.
- Maths warm-ups: spin twice and add, subtract or multiply the results.
- Replacing dice: use 1–6 for board games when the dice have gone missing, or 1–12 for two dice' worth of range.
- Bingo: set 1–75 or 1–90 with no repeats and read out each call.
- Raffles: enter your ticket range and let the rolling counter draw the winning number.
Every number has the same chance
The number is chosen the instant you press spin, using your browser's cryptographically secure random generator, crypto.getRandomValues, before any animation starts. The wheel or counter then simply shows that result. Because the choice uses an unbiased method, 7 is no luckier than 1 or 10, and a long range is just as even as a short one.
Frequently asked questions
What's the largest range I can use?
Any whole numbers between minus one billion and one billion. Ranges of more than 100 numbers use the rolling display instead of the wheel.
Can I pick several numbers at once?
Spin once per number with Don't repeat numbers switched on. The history lists every pick in order, newest first.
Is my history saved?
Yes, in this browser only, along with your range and settings. Press Clear to start fresh.
Why are some numbers hidden on the wheel?
On small screens a 1–100 wheel has very thin slices, so the labels are hidden to keep it tidy. The picked number is always shown in full.
