How the random number generator works

Set a minimum, a maximum, and how many numbers you want, then press "Generate." Each number is picked with your browser's random number generator, giving every value in range an equal chance.

Turn on "No duplicates" to draw each number at most once — useful for things like raffle numbers or lottery-style picks. Turn it off if repeats are fine, like simulating dice rolls.

Common uses

  • Drawing raffle or lottery-style numbers
  • Picking a random sample size, quantity, or ID for testing
  • Simulating dice rolls or other random draws
  • Generating a quick random number for a game or decision

FAQ

What happens if I ask for more unique numbers than the range allows?
You'll get an error — for example you can't draw 10 unique numbers from a range of 1 to 5. Widen the range or lower the quantity.
Can min and max be negative?
Yes — any whole numbers work, as long as min is less than or equal to max.
Is this suitable for anything high-stakes?
It's a solid general-purpose random generator, but for regulated drawings (official lotteries, etc.) check whatever certification is legally required in your case.
