Frequently Asked Questions
- Is the result truly random?
- Yes. Numbers come from the browser's cryptographic random generator, which is suitable for raffles and sampling.
- Can I generate numbers without repeats?
- Yes. Turn on "unique values" and every number in the list will be different.
- What happens if I ask for more unique numbers than the range holds?
- The tool tells you the range is too small rather than returning duplicates.
