Formule
Numbers come from the browser's cryptographically secure generator. Rejection sampling ensures every integer in the range is exactly equally likely, and unique draws use a Fisher–Yates shuffle.
P(any integer in [min, max]) = 1 / (max − min + 1)
Questions fréquentes
Are the numbers truly random?
They come from your operating system's cryptographic random source, which is suitable for security purposes and far better than typical pseudo-random functions.
How do I pick lottery numbers?
Set the range (e.g. 1 to 49), the count (e.g. 6) and keep 'no repeats' ticked. Every combination is equally likely.
Can I use this for a giveaway?
Yes. Number the entries and draw the needed number of unique winners. For transparency, record your screen or have a witness.
