How it works
Set a range, choose how many numbers you need, and generate. Turn off duplicates when you are drawing raffle tickets or picking a team, and leave them on when each draw should be independent.
Example: A range of 1 to 49 with six unique numbers gives you a typical lottery line in one tap.
Questions people ask
How random are the numbers?
They come from your browser's cryptographic generator. We also discard the small tail of values that would otherwise make low numbers slightly more likely, so every value in the range is equally probable.
What does “no repeats” do?
It draws without replacement, like pulling tickets out of a hat. If you ask for more numbers than the range holds, you get every value once.
Does anything get sent to a server?
No. The numbers are generated in your browser and never leave your device.
