Random Number Generator
Pick a random number between any two values. Draw one or draw hundreds, sorted, with or without repeats - for giveaways, raffles and classrooms.
A random number generator picks a value between a minimum and a maximum with every number in the range equally likely. For a draw between 1 and 100 that means each number has a 1% chance. Turn repeats off when you are picking winners or assigning unique tickets, and leave them on when each draw should be independent, like a dice roll.

Frequently asked questions
How do I pick a random number between 1 and 100?
That is the default. Press generate and you get one number, with every value from 1 to 100 equally likely.
What is the difference between repeats on and off?
With repeats on, each draw is independent and the same number can come up twice - like rolling a die. With repeats off, numbers are drawn without replacement, like pulling raffle tickets from a hat.
Is this random enough to pick a giveaway winner?
Yes for an informal draw. For anything with legal or prize-money weight, use a service that publishes a verifiable seed, so entrants can check the draw was not re-run.
Are the numbers truly random?
They are pseudorandom: generated by an algorithm in your browser that is statistically random but not physically so. For games, classrooms and giveaways this is indistinguishable from true randomness.
Can I use negative numbers?
Yes. Any whole numbers work as the minimum and maximum, including negatives, and they can be entered in either order.
How many numbers can I draw at once?
Up to 1000 with repeats on. With repeats off the limit is the size of the range, since you cannot draw 50 unique numbers from a range of 10.
Does anything get sent to a server?
No. The numbers are generated in your browser and nothing about the draw is transmitted, logged or stored.
Why are the results sorted?
Only when repeats are off, because that mode is for picking a set rather than a sequence and a sorted set is easier to check against a list. With repeats on the draw order is preserved.
