How number checking works

Save a set of 5 Powerball numbers plus your Powerball — it’s stored locally in your browser, not on our servers. Each saved set is checked two ways: against the last 20 drawings for partial matches (how many of your 5 numbers, plus whether your special ball, landed in a recent draw), and against every drawing in our archive since 2023 for whether your exact combination — or just your 5 white balls with a different Powerball — has ever been drawn. We also show each number’s historical draw frequency as a percentile of the most-drawn number, so you can see how common or rare your picks have been.

See the FAQ for more on how hot, cold, and frequency statistics are calculated, or read About for where the draw data comes from. As always: every drawing is independent, and no saved set is more or less likely to win than any other.
