When to use it

Use this tool to pick random numbers for games, raffles, giveaways, classroom activities, sampling, statistics exercises or just settling a choice. It can pick one number or many, with or without repeats, as whole numbers or decimals.

How to use it

  1. Enter the range in From and To.
  2. Set How many numbers you want, from 1 to 1,000.
  3. Choose Decimal places: None (whole numbers), 1, 2 or 3.
  4. Tick No repeats (every number different) and Sort from smallest to largest if needed.
  5. Or tap a preset: 1–10, 1–100, Dice 1–6 or Lottery 6 of 49.
  6. Press Generate, then Copy to copy the result.

Worked examples

Picking a raffle winner: you sold tickets numbered 1 to 250. Set From 1, To 250, how many 1, and press Generate. The number shown is the winning ticket. For three prizes, set how many to 3 and tick No repeats, so the same ticket cannot win twice.

Lottery numbers: tap Lottery 6 of 49. The tool picks six different numbers from 1 to 49 and sorts them, for example 9, 11, 24, 26, 47 and 48.

Classroom: with 28 students numbered on the register, generate one number from 1 to 28 to choose who answers next.

Why not just pick a number yourself?

People are poor at being random. When asked for a number from 1 to 10, many choose 7, and we tend to avoid repeats and patterns that real randomness produces all the time. A generator removes that bias, which matters for fair draws, surveys and science experiments.

Tips

  • Write down the settings first. For a public draw, announce the range and rules before you press Generate.
  • Use No repeats for groups. To split 30 people into teams, generate all 30 numbers without repeats and take them in order.
  • Copy the result straight away. Each press of Generate gives new numbers.
  • Sort long lists. Sorted numbers are easier to read and check.

Common mistakes

  • Asking for more unique numbers than the range holds. You cannot pick 10 different numbers from 1 to 5.
  • Thinking some numbers are “due”. Each draw is independent. A number that has not appeared for a while is no more likely next time.
  • Forgetting decimals affect the range. From 1 to 2 with one decimal place gives values like 1.3 or 1.9, not just 1 or 2.

Frequently asked questions

Are the numbers truly random?

They come from your browser's cryptographic random number generator, the same kind used for security, so every number in the range is equally likely and the results cannot be predicted.

Does the range include both ends?

Yes. From 1 to 100 can give 1, 100 or anything in between.

What does No repeats do?

It makes every number in the result different, like drawing numbered balls from a bag without putting them back. It is useful for raffles, lotteries and picking several winners.

Can I get decimal numbers?

Yes. Choose 1, 2 or 3 decimal places to get values like 42.7 or 3.142 within your range.

Can I use it for an official prize draw?

It is fair and unpredictable, but some competitions have legal rules about how winners are drawn. Check the rules where you live, and record the draw, for example with a screen recording, so it can be verified.
