    Good to know

    What does “no repeats” do?

    It remembers what has already come out and draws only from what is left, so a range can be worked through to the end without anything appearing twice. The numbers already used are listed under the draw, and Clear starts the range again.

    How big a range can I use?

    Any two whole numbers up to a million apart. The pages listed above cover the ranges that are asked for by name; for anything else, type the two ends into the tool and it works the same way.

    Is it evenly random?

    Yes. The draw comes from your browser’s cryptographic random source, scaled to the range without the rounding bias that a plain remainder introduces, so every number in the range is equally likely.
