Random Number Generator: Pick Numbers Instantly

This free random number generator picks numbers in any range you set — one number or up to 100 at once, with optional unique (no repeats) and sorted output. Raffles, samples, passwords-with-digits, classroom picks — done in one click.

How to generate numbers

1. Set your range — minimum and maximum (they can be negative, and min/max auto-swap if reversed).
2. Choose how many — 1 for a single pick, up to 100 for a full set.
3. Tick options: Unique guarantees no repeats; Sort orders the results.
4. Generate. Done — again and again, free.

When to use “unique”

• Raffles & draws: unique numbers mean no ticket wins twice.
• Lottery-style picks: real lotteries never repeat a main number — unique + sorted mimics a real ticket line.
• Sampling: pick 10 unique students from a class list numbered 1–30.
• Leave it off for dice-style rolls, where repeats are natural (two dice can both show 4).

True randomness is a deep topic — computers use special algorithms or hardware for it. Ours uses your browser’s cryptographic RNG; for the full story see Wikipedia on random number generation.

What people generate numbers for

• Giveaways: pick a winning comment or ticket number transparently.
• Teachers: random student picker, random groups, random quiz questions.
• Games: bingo-style draws, guessing games (“I’m thinking of a number…”), RPG tables.
• Research: random sampling for surveys and experiments.
• Passwords & PINs: a random 6-digit number makes a decent PIN (but use our Password Generator for real security).
