Random Number Wheel 1 to 100
This wheel picks a random number from 1 to 100, the range people mean when they say "pick a number" and want the answer to feel genuinely unguessable.
One hundred slices, each holding one percent of the wheel.
A hundred is roughly where a wheel stops being readable mid-spin and becomes a colourful blur that resolves into an answer. That is fine. The number is announced when it stops, and the blur is arguably better theatre than a slow, legible wheel.
Guessing games are the common use. One person spins in secret, the other guesses, and higher-or-lower does the rest. It also handles percentage prompts, random sampling from a numbered list, and the kind of arbitrary target that makes a workout or a chore feel like a game rather than an obligation.
Statistics teachers use it as a live demonstration. Spin twenty times, tally the results, and the distribution will look nothing like even — which is exactly the lesson. If you want to run that properly, the fairness page does the same thing up to 100,000 spins and reports a chi-squared result.
Random Number Wheel 1 to 100 — questions
Does every number really have a one percent chance?
Yes. All hundred slices are equal and the draw uses a cryptographically secure generator. You can verify the distribution yourself on the fairness page by running up to 100,000 simulated spins.
The wheel is a blur — is that a problem?
No. At a hundred slices the spin is deliberately a blur; the winning number is displayed clearly when it stops. If you need to read the wheel during the spin, use a smaller range.
Can I go above 100?
The random number wheel takes any minimum and maximum up to a 200-number span. Beyond that, a wheel is the wrong shape for the job and a range picker is more practical.
