FAQ
Are the numbers truly random?
They use crypto.getRandomValues, the browser's cryptographically secure generator — far better than Math.random() for fairness, and inclusive of both endpoints.
What does "no repeats" do?
It draws distinct values, like a lottery draw. You can't request more unique numbers than the range contains.
Are the endpoints included?
Yes. Both the minimum and maximum you enter can appear in the results.
