FAQ

How random are the numbers?

They come from crypto.getRandomValues() — the browser's cryptographic generator, suitable even for raffles and giveaways.

Can I get numbers without duplicates?

Yes — enable “unique only” and every number in the batch is different (the range must be large enough).

What's the maximum range?

Any integers from -1,000,000,000 to 1,000,000,000, up to 100 numbers per draw.
