About the randomness
Numbers come from your browser's cryptographically secure random generator and are mapped to your range without modulo bias, so every number between your min and max is equally likely. Ranges of up to about 4 billion numbers are supported, and negative numbers work too.
Frequently asked questions
Can I generate negative numbers?
Yes, set a negative minimum, for example -50 to 50.
Why can't I get 10 unique numbers from 1 to 5?
With no duplicates allowed, you can't draw more numbers than the range contains. Widen the range or lower the count.
Is this suitable for official lotteries?
It is fine for informal draws. For legally regulated lotteries, always follow the rules and certified tools required in your jurisdiction.
