🔢 Random Number Generator

They come from crypto.getRandomValues — a cryptographically secure generator seeded by your operating system, the same class of randomness used for encryption keys. Unlike basic Math.random(), the sequence can't be predicted or reproduced.

Yes — switch off 'allow duplicates' and every number in your draw is unique, like pulling numbered balls from a drum without putting them back. Handy for raffles, prize draws and secret santa orderings.

Raffle draws, picking random winners by entry number, choosing lottery numbers, random sampling for a survey, or settling anything a dice roll is too small for. If you need 1–10 with drama, try the Lucky Number Wheel instead.
