Every press produces a fresh, independent draw.
Random number questions, answered
How random are these numbers?
They come from your browser's crypto.getRandomValues - the same cryptographic source used for security keys, far stronger than the Math.random most sites use.
Are min and max included?
Yes, both ends are inclusive: a 1–10 range draws from exactly ten values.
Can I draw raffle winners with it?
Yes - set the range to your ticket numbers, the count to the number of winners, and enable No repeats so nobody wins twice.
Is anything logged?
No. Numbers are generated locally and never sent anywhere - there is no server to log them.
