Random number FAQ
How do I generate a random number?
Set the min and max and click Generate — a fair whole number in that range appears. Free, no sign-up.
Can I get no repeats?
Yes — "No repeats" draws each number only once until the range is used up or you reset.
Is it truly random?
Yes — it uses the browser's random generator, so every number is equally likely.
