How to use the Random Number Generator

  1. Set the minimum and maximum.
  2. Choose how many numbers and whether repeats are allowed.
  3. Press Generate.

What does this tool do?

“No repeats” draws numbers like balls from a bag, so each can appear only once — ideal for raffles and lottery-style picks. With repeats allowed, each number is independent, like rolling a die.

Why use it?

  • Raffles and prize draws.
  • Random samples for surveys and audits.
  • Games and classroom activities.

Example

6 numbers from 1 to 49 with no repeats, sorted: a typical lottery-style pick.
