Random Number Wheel

A random number generator you can watch

The Random Number Wheel is a number generator with a show. Enter a minimum and maximum, press spin, and the wheel lands on a random whole number in your range. Because everyone can see the wheel turning, it feels more trustworthy than a number simply appearing on screen — great for classrooms, raffles and live streams.

How to pick a random number

1. Enter the From and To numbers, or tap a preset like 1–10, 1–100 or 0–9.
2. Turn on Don’t repeat numbers if each number should only come up once.
3. Press Spin. The result pops up and is added to your Results list.
4. Use Put all numbers back to start a fresh round.

Small ranges and huge ranges

For ranges up to 300 numbers, every number gets its own slice on the wheel. For bigger ranges — say 1 to 1,000,000 — the wheel shows a sample of 24 numbers so it stays readable, but the result is still drawn fairly from the entire range. Every whole number between your minimum and maximum has exactly the same chance.

Ways to use a number wheel

• Bingo and lotto calling with “don’t repeat” switched on.
• Raffle tickets — spin the winning ticket number.
• Maths lessons — random numbers for times tables, rounding or place-value practice.
• Games night — choose a page number, a level or a random player order.
• Exercise reps — let the wheel decide 10 to 30 push-ups.

Prefer a classic raffle with named tickets and multiple winners? Use the Raffle Wheel. Need dice for a board game? The Dice Roller handles d4 to d100.

Is it truly random?

The number is chosen with crypto.getRandomValues() using rejection sampling, which avoids the small bias that simpler “random times range” methods can introduce. In practice this means no number is favored, even across millions of spins.
