Questions
Are the results suitable for a lottery or a draw?
They are uniformly chosen with a cryptographic generator, which is appropriate for informal draws. A regulated competition may require its own witnessed procedure.
Why can’t I get more unique numbers?
There are only so many distinct integers between the minimum and the maximum. The tool stops rather than repeating when unique mode is on.
