How it works

Values come from crypto.getRandomValues, the browser's cryptographically secure random source, mapped into your range without modulo bias. Unique mode draws without replacement so no value repeats.

Frequently asked questions

Is this truly random?

It uses the operating system's secure entropy pool — far stronger than Math.random and suitable for draws and giveaways.

Can I generate lottery numbers?

Yes. Set the range, choose how many numbers, and turn on unique values so nothing repeats.
