Content updated .
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.
Frequently asked questions
Does No duplicates make every result unique?
Yes, within the current batch. Separate batches can contain the same numbers. The range must contain at least as many values as the requested quantity.
Can this predict a lottery result?
No. It samples integers using the browser's random source; it does not predict external events.
