The Random Number Generator lets you create one or many random numbers within any range you choose. Set a minimum and maximum, pick how many numbers you need, and decide whether repeats are allowed. It is useful for picking lottery numbers, assigning random order, running classroom activities, raffles, games and statistical sampling.
How to use the random number generator
- Enter the minimum and maximum values for your range.
- Set how many numbers you want to generate (1 to 1000).
- Tick "No repeats" if you want every number to be unique.
- Click Generate Numbers to see your results instantly.
Common uses for random numbers
- Raffles and draws — assign each participant a number and pick a random winner.
- Classroom games — generate random numbers for maths quizzes or student selection.
- Lottery and lucky picks — generate number combinations for games like Tambola or local lotteries.
- Decision-making — assign options to numbers and let randomness choose.
- Testing and sampling — pick random samples from a dataset for quality checks.
How random is it?
This tool uses the crypto.getRandomValues() API in modern browsers, which generates cryptographically strong random values. For everyday purposes — games, draws, picking — this is far more random than any manual method. For scientific or cryptographic use, always use a purpose-built library and consult relevant standards.
