What is a random number generator?
It picks integers from a closed range, either independently or without repeating a value.
How to use it
- Set the minimum, maximum, and how many numbers you need.
- Turn off Allow duplicates when each value may appear only once.
- Generate and copy the list.
FAQ
Are the numbers cryptographically random?
They come from a cryptographically secure generator. That is stronger than a programming-class Random() shuffle.
Why did unique mode fail?
You asked for more numbers than the range contains. Widen the range or allow duplicates.
