How random numbers work
This tool uses your browser's built-in cryptographically secure random number generator (where available) or a high-quality pseudo-random source. Numbers are generated instantly, locally, and never leave your device. Use it for raffles, dice rolls, lottery picks, classroom selection, or any time you need fair chance.
Unique vs. duplicate numbers
Toggle "Allow duplicates" off when you need a set of unique numbers — like drawing lottery balls or selecting winners without replacement. If you request more unique numbers than exist in your range, the tool automatically returns every number in the range once.
