Random Number Generator
Generate random numbers in any range, with or without repeats.
Your numbers
49, 14, 67, 100, 50
Edit any field to draw again. Uses the browser's PRNG — fine for picks and games, not for cryptography.
Uniform and independent
Each draw is uniform across the range — every integer equally likely — and independent of previous draws, which is why repeats happen more often than intuition expects (with 23 people, two share a birthday more often than not). Switch to unique mode for raffle-style picks.
Pseudo, not magic
Computers generate 'random' numbers deterministically from an internal seed. Browser PRNGs pass statistical tests and are fine for games and sampling; lotteries and cryptography use hardware entropy instead.
