How this random number generator works
Every draw uses your browser's built-in random number generator to produce values on the fly. In range mode, it picks whole numbers between your minimum and maximum, inclusive. When repeats are turned off, the tool shuffles the full set of possible values and takes the first few, so every number in the result is unique.
Range mode vs. list mode
Use range mode when you need numbers — a lottery pick, a dice-like roll over an arbitrary span, a random sample of row numbers, or a quick decision between numbered options. Use list mode when the choices are words or names: pulling a raffle winner, shuffling teams, or picking a random restaurant from your shortlist. Turning off repeats in list mode guarantees no one is drawn twice.
Where a random generator is useful
- Raffles and giveaways: paste the entrants and draw one or more winners fairly.
- Games and lotteries: generate lucky numbers within any range you choose.
- Sampling: pick random record numbers for a quick, unbiased sample.
- Decisions: settle a choice at random when every option is fine.
- Teaching: demonstrate randomness, probability and sampling in class.
Frequently asked questions
Are these random numbers truly random?
They use the browser's built-in random number generator, which is well suited for raffles, games, sampling and everyday use — but not the cryptographically secure randomness needed for things like security keys.
Can I generate numbers without duplicates?
Yes. Set "Allow repeats" to No and every number drawn will be unique. In that mode you can't draw more numbers than the range contains — for example, at most 10 unique numbers between 1 and 10.
Can I use it for a raffle or to pick a winner?
Yes. Switch to the "From a list" tab, paste the names or entries one per line, choose how many to pick and whether repeats are allowed, then press Generate.
