How to Use Random Number Generator

1

Enter the lowest and highest number you want in the minimum and maximum fields, checking that the minimum is not set above the maximum.

2

Set how many values to draw, and tick the checkbox for whole numbers only if you do not want decimal places in the result.

3

Choose whether repeats are allowed; switching repeats off makes the tool draw every number in the range before it reuses any of them.

4

Click the "Generate" button, read the result together with the history list underneath it, then copy or download the draw if you need to keep a record.

Frequently Asked Questions

It uses a cryptographically secure random source supplied by your browser, so results cannot be predicted by watching what came out earlier. That is considerably fairer than a dice roll or a name pulled from a hat.
That depends on the repeat setting you choose. Leave repeats on to draw with replacement, or turn them off to draw without replacement until every number in the range has been used exactly once.
Yes, there is no cost and no account needed. For a public competition involving money, check the rules where you live, since some jurisdictions require a formally audited random process rather than an online generator.
It does. The range is inclusive, so a draw between 1 and 10 can return either 1 or 10, and the total number of possible outcomes matches the size of the range exactly.

About Random Number Generator

Choosing a number fairly is harder than it sounds, and that holds true whether you are drawing a prize at a school raffle or picking questions for a quiz. This Random Number Generator removes the guesswork by producing a genuinely unpredictable value inside the exact range you define, so every option in that range carries an identical chance of being drawn.

Set a minimum and a maximum and the result is drawn inclusively, meaning both end points can appear. Turn repeats off and the tool keeps drawing until it has used every available number in the range, which makes it a good way to split a class into groups or deal out a full set of cards. If you need decimals rather than whole numbers, widen the precision setting and you will get values such as 8.42 instead of 8.

It also covers the practical side of a real draw: a visible history of previous results, the number of values still available, and an honest count of how many outcomes the range contains. That combination of a clear audit trail and strict range control is why it gets used for classroom lotteries, exam question selection, quick team picking, stand-up meeting order, and randomised social media giveaways.

Key Benefits

  • Impartial draws where every value in the range is equally likely
  • Inclusive minimum and maximum, so 1 to 10 can genuinely return 1 and 10
  • Repeat control for dealing cards or picking without duplicates
  • History of previous results kept as a verifiable record
  • Handles whole numbers and decimals inside the same tool
