How to pick a random number

Set the lowest and highest numbers you want (both are included), choose how many numbers you need, and press Generate. Tick No repeats when every number should be different, for example drawing raffle tickets or lottery-style picks.

Is it truly random?

The numbers come from your browser's cryptographically secure random generator (the Web Crypto API), with no rounding bias, so every number in the range is equally likely. That makes it more than good enough for games, raffles, classroom picks and sampling.

Popular ranges

  • 1 to 10: guessing games and quick picks
  • 1 to 100: the classic "pick a number"
  • 1 to 6: a single die (or try the dice roller)
  • Ticket numbers: set the first and last ticket in your raffle

Frequently asked questions

Can I generate negative numbers?
Yes. Set a negative minimum, for example −50 to 50.
Can I use this for real lottery numbers?
You can use it to choose numbers, but no generator can improve your odds. Every combination is equally likely to win.
