Random Number Generator
For giveaways, sampling, games and test data. Numbers come from the browser's cryptographic random source rather than a simple pseudo-random function, and the no-repeats option turns it into a fair draw.
How to use it
- Set the minimum and maximum, both included.
- Say how many numbers you want.
- Tick no repeats for a raffle-style draw, then generate.
Examples
- 1 to 100, one number: a simple pick.
- 1 to 50, six numbers, no repeats: a lottery-style line.
- 0 to 1000, 200 numbers: quick filler data for a test.
Questions people ask
Is the result truly random?
It uses the browser's cryptographically secure generator, which is unpredictable for any practical purpose including prize draws. True physical randomness needs dedicated hardware, but nothing here is guessable from previous results.
Are the endpoints included?
Yes. Both the minimum and the maximum can come up, so a range of 1 to 6 behaves exactly like a die.
