Frequently Asked Questions
Can I generate multiple unique numbers?
Yes — check “No repeated numbers” to draw each number only once, useful for things like raffle draws or picking a unique set.
How random is this really?
It uses your browser's Web Crypto API (crypto.getRandomValues), a cryptographically secure random source — stronger than the basic Math.random() many simple generators use.
