- Press Generate.
What does this tool do?
“No repeats” draws numbers like balls from a bag, so each can appear only once — ideal for raffles and lottery-style picks. With repeats allowed, each number is independent, like rolling a die.
Why use it?
- Raffles and prize draws.
- Random samples for surveys and audits.
- Games and classroom activities.
Example
6 numbers from 1 to 49 with no repeats, sorted: a typical lottery-style pick.

Frequently asked questions
Is it truly random?
Results come from crypto.getRandomValues, your browser's cryptographically secure random generator, with an unbiased method of picking from a range — so every outcome is equally likely.
Can I use it for a raffle or prize draw?
It's fine for informal draws like classroom raffles or office giveaways. Regulated lotteries and some prize promotions have legal rules about how winners are drawn, so check those first.
