Random Number Generator

Generate truly random integers for dice, draws, sampling or simulation — with full control.

How to Use This Generator

Are these numbers truly random?

They use crypto.getRandomValues, which is cryptographically strong — good enough for games and draws, though not for cryptography-critical use.

Why can't I generate without duplicates?

Because you asked for more numbers than the range contains. The count must be ≤ max − min + 1.

Can I generate negative numbers?

Yes — set a negative minimum, like −50 to 50.

What if I generate the same sequence?

Every run is independent, so repeating the same settings gives a fresh set each time.

Common use cases:

Roll a d6 — set 1–6, count 1 → any value from 1 to 6, each equally likely.
Pick a lottery-style set — 1–49, count 6, no duplicates → six unique numbers.
Assign numbers to students — 1–30, count 30, no duplicates → every number used exactly once.

Uniform randomness — every integer in the range has an equal chance.
Duplicates allowed — each pick is independent, like rolling dice repeatedly.
Duplicates not allowed — a fair draw without replacement, like pulling names from a hat.
