Frequently asked questions
Is this suitable for a giveaway or raffle draw?+
Yes, it uses a cryptographically secure random source with unbiased rejection sampling, and "no duplicates" mode guarantees each number is picked at most once.
What happens if I ask for more unique numbers than the range allows?+
You'll get an error, since it's mathematically impossible to draw more unique numbers than exist in the range.
Can min and max be negative?+
Yes, any integer range is supported as long as min is less than or equal to max.
