Generate random numbers in any range
This generator picks a random number between any two values you set. It is useful for draws, sampling, games, and any decision where you want an outcome nobody chose.
Numbers produced here come from your browser's pseudorandom generator. That is entirely appropriate for games and raffles, though not for cryptographic purposes, which need a different class of generator.
The most persistent misconception is the gambler's fallacy: the belief that a result which has not appeared for a while is somehow due. Each generation is independent, so a number that came up three times running is exactly as likely as any other on the next attempt.
Genuinely random sequences also look far less even than people expect. Clusters and repeats are normal, and a sequence that appears suspiciously patterned is usually just what randomness actually looks like over a small number of trials.
They come from your browser's pseudorandom number generator, which is statistically sound for games, draws, and sampling. It is not suitable for cryptography, which requires a cryptographically secure generator.
Yes, and it should. Each generation is independent of the last, so repeats are expected and are not a sign that anything is wrong.
Yes. Number your entrants sequentially and generate within that range. For draws where the outcome is contested, generating in front of witnesses is worth doing.
Over a small number of generations, clusters are normal. Genuinely random sequences look much less evenly spread than intuition suggests, and apparent patterns usually disappear over more trials.
