Random number generator

How to use it

Step 1

Enter the lowest and highest number of your range, and how many numbers you want.

Step 2

Choose whether numbers may repeat. Without repeats, each number in the range appears at most once.

Step 3

Press draw. The winning numbers show on screen, and you get a result link to share.

What makes the draw verifiable

Before drawing, the server creates a seed: a 32-byte value that neither you nor we pick. That seed, your range and the algorithm version are stored with the result. Because the method is public and deterministic, anyone with those inputs arrives at exactly the same numbers.

The result link is where those inputs are published. Whoever receives it can run the verification, which redoes the draw in their own browser and compares the output. If a single number differs, the result does not check out. The algorithm page explains every step.
