Each number from 1 to 20 has an equal 1 in 20 (5.0%) chance. This range is handy for a d20 roll in tabletop games. Change the min and max above for any other range.
FAQ
Is it truly random?
Numbers come from your browser's cryptographically secure random generator and are unbiased across the range (we use rejection sampling to avoid modulo bias).
Can I use it for giveaways?
Yes. Assign each entrant a number and generate one; for fairness, share your screen or record it.
