How the numbers are drawn
Whole numbers between your minimum and maximum, both included, from your browser's cryptographic random generator. You can draw up to 1,000 at once. With "Unique numbers only", you can't get more numbers than the range holds — asking for 20 unique numbers from 1 to 10 gives all ten. If the minimum is larger than the maximum, they're swapped.
A lottery-style draw
For 6 numbers from 49: set Min to 1, Max to 49, How many to 6, tick "Unique numbers only" and press Generate. For a raffle with numbered tickets, draw one number between the first and last ticket number.
