Random Number Generator
Pick a random integer or generate up to 100 numbers. Set your range and choose whether duplicates are allowed.
How to use it
Enter a minimum, maximum and quantity. Both endpoints are included. Select No duplicates for sampling without replacement, or Sort smallest first for an ordered result.
Useful example
For a six-number draw from 1 to 49, set Minimum to 1, Maximum to 49, quantity to 6 and enable No duplicates.
Tips
Randomness comes from the browser's cryptographic random source with rejection sampling to avoid modulo bias. Use whole-number bounds with a span no larger than 4,294,967,296. This tool does not predict lottery outcomes.
