Random Number Generator

Pick fair random numbers for draws, contests, lotteries and games.

Fair by design

Numbers come from the browser's cryptographically secure generator, with rejection sampling so every number in your range is equally likely. There is no bias towards low numbers.

Uses

  • Picking giveaway winners by comment or entry number.
  • Seat and roll-number allotment.
  • Dice, games and classroom activities.

Frequently asked questions

Is it truly random?

It uses crypto.getRandomValues, the same secure source used for encryption keys, so results are unpredictable.

How do I pick 3 winners from 250 entries?

Set min 1, max 250, how many 3, and tick 'No repeats'.

Is anything recorded?

No. Numbers are generated in your browser.
