Frequently Asked Questions
Where the numbers come from, and what this page does not do.
Does this run in my browser?
Yes. Numbers stay in this browser and are never uploaded. You can confirm in DevTools Network if you want.
How strong is the randomness?
The generator uses the secure random source built into this browser. Nothing is sent.
Can I generate decimals?
Integers only is the default, so the draw is whole numbers. Turn Integers only off and a decimal places field appears. It sets how many places to keep, from 1 to 10. That field is hidden while Integers only is on.
What if unique count is larger than the range?
Turn Allow duplicates off to draw unique values. The count cannot be larger than the number of integers in the range. Generate stops with a message when it is.
Does sort change the draw?
No. Sort results only changes the order you see. The numbers drawn stay the same.
Is this an official lottery system?
No. This is a local generator for your own use. It is not a lottery, raffle, or gambling system.
