About this random number generator

The classic random number generator: pick any minimum and maximum, choose how many numbers you need, and get instant results. Enable "No duplicates" for raffle draws and lottery-style picks, or sort the output for clean lists. Negative numbers work too — just type them in.

Every draw uses cryptographic-quality randomness, so each number in your range has an exactly equal chance. That matters when the draw has real stakes — a raffle winner, a bingo caller, or a random sample for a survey or classroom statistics demo. Unlike "pick a number" games where humans unconsciously favor certain digits, this tool has no favorites.

How to use it

  1. Set your Min and Max (any whole numbers, e.g. 1–100).
  2. Choose how many numbers to draw (up to 100).
  3. Tick No duplicates for raffle-style draws, Sort results for tidy lists.
  4. Hit Generate — tap again for a fresh draw anytime.

Popular uses

  • Raffles & giveaways: assign ticket numbers and draw winners without duplicates.
  • Bingo & lottery-style games: draw sorted, unique numbers just like the real thing.
  • Board games: a substitute for any die — d100, d1000, whatever you need. Or use our dedicated dice roller.
  • Teaching probability: run 100 draws and watch the distribution even out — a vivid statistics demo. See our coin flip probability guide for the math behind randomness.
  • Random sampling: pick survey respondents or test cases fairly.
  • Decisions: "pick a number between 1 and 10" — settled in one tap.

Frequently asked questions

How do I generate a random number between 1 and 100?

Set Min to 1, Max to 100, choose how many numbers you want, and press Generate.

Yes — every number in your range has an exactly equal chance, using cryptographic-quality randomness.

Can I generate random numbers without duplicates?

Yes. Keep "No duplicates" checked and you'll get a unique set — ideal for raffle draws, lottery-style picks, and bingo numbers. The count is automatically capped at the size of your range.

What is a random number generator used for?

Raffle and giveaway draws, lottery-style picks, bingo numbers, dice substitutes in board games, random sampling for surveys, probability demonstrations in classrooms, and quick everyday decisions.

Can I sort the generated numbers?

Yes — tick "Sort results" to get your numbers in ascending order, handy for lottery tickets and clean lists.

What's the biggest range I can use?

A dice roller simulates physical dice (1–6, 1–20, etc.), while this generator works with any custom range — 1–1000, 50–75, or whatever your game or draw needs.
