Are these numbers really random?
They come from your browser’s cryptographic random generator (the same one used for encryption keys), and whole numbers are drawn without bias, so every number in the range is equally likely.
Can I use it for a raffle or lottery?
Yes. Set the range to your ticket numbers, the count to the number of winners and tick “No repeats”.
