About the Random Number Generator
Set a range and how many numbers you need, and get a random draw — optionally with no repeats. Adjust any setting to reshuffle. Handy for drawings, games, sampling, and picking winners.
How it’s calculated
Each number is drawn uniformly from the inclusive range. 'All unique' samples without replacement so no value repeats.
Example calculation
Between 1 and 100, drawing 5 unique numbers might give 8, 24, 28, 80, 98.
Frequently asked questions
Are the numbers truly random?
They use the browser's built-in pseudo-random generator, which is fine for games, drawings, and everyday use — but not for cryptographic or security purposes.
How do I get a new set?
Change any field — the range, the count, or the unique setting — and a fresh set is drawn instantly.
