Random Number FAQ
How random are the generated numbers?
We use the browser's crypto.getRandomValues() function, which provides cryptographically secure randomness. This is far more random than Math.random() and suitable for most applications including lotteries and games.
Can I generate unique (non-repeating) numbers?
Yes. Enable "unique numbers only" and the generator will not repeat any number within the specified range. This is useful for raffles, lottery picks, and random sampling.
