Random Number Generator — FAQs
Is it truly random?
It uses the browser’s cryptographic RNG (crypto.getRandomValues) — unpredictable and unbiased, far better than basic Math.random().
Can I exclude duplicates?
Yes — toggle ‘unique only’ for lottery-style draws where each number can appear once.
Why do humans pick bad random numbers?
We avoid edges and repeats: asked for 1–10, most people say 7. Machines don’t have that bias.
Can I use this for a giveaway?
For casual draws, yes. For regulated lotteries or gambling, use certified hardware randomness instead.
