    Questions and answers

    Is the result really random?

    Yes. Numbers come from your browser’s cryptographic random generator, and every number in the range has the same chance.

    How do I pick numbers with no repeats?

    Tick No repeats: each number can come out only once, like drawing tickets from a hat. You can draw up to the size of the range.

    Can I use it for a raffle?

    Yes. Set the range to the ticket numbers (for example 1 to 500) and generate the winners with No repeats ticked.

    Does it predict lottery numbers?

    No. Lottery draws are random, so no tool can predict them. The quick picks only generate valid random combinations.
