Frequently Asked Questions
Is this truly random?expand_more
Yes. We use the Web Crypto API (crypto.getRandomValues), the same cryptographically secure random source browsers use for security-sensitive operations, instead of the weaker Math.random().
Can I generate numbers without repeats?expand_more
Yes, disable "Allow duplicate numbers" to draw unique values, similar to how lottery balls are drawn without replacement. Unique draws need a range of 5,000,000 or smaller.
Is this good for raffles and giveaways?expand_more
Absolutely. Set your range to match your ticket numbers, disable duplicates, and generate as many winners as you need in one click.
