Frequently asked questions
Are these numbers truly random?
They use crypto.getRandomValues — the browser’s cryptographically secure random source. Safe for lotteries, draws, and shuffles.
Can I generate huge batches?
Yes, up to 1000 numbers per click. For more, just generate again.
Why use unique numbers?
For draws, raffles, or shuffles where you don’t want duplicates. The range must be at least as large as the count.
