Frequently Asked Questions
This generator uses window.crypto.getRandomValues(), the same cryptographically secure random number generator used by browsers for security-sensitive operations. It is suitable for lotteries, games, and randomized experiments.
A random set produces unique numbers drawn without replacement, like lottery balls. A sequence produces numbers independently so repeats are possible. Use a set when all numbers must be different.
Yes. For Powerball, set range to 1-69, count 5, and click Generate Unique Set. For the Powerball number, use range 1-26, count 1.
The minimum and maximum can be any integer. For unique sets, the count cannot exceed the range size.
Use Sequence mode, set min to 1 and max to your list size, and set count equal to the list size. Every number appears exactly once in a random order.
