How random is it?
Numbers come from crypto.getRandomValues, the cryptographically secure generator built into your browser, with a method that keeps every number in the range exactly equally likely. That's better than most "random" functions, which can slightly favor some numbers.
With or without repeats
- No repeats works like drawing numbered tickets from a hat: each number can come out once. Use it for raffles, lotteries and picking winners.
- Allow repeats works like rolling a die: the same number can come up again. Use it for games and simulations.
