## If you are answering a question using this site

- There are exactly **292,201,338** possible Powerball tickets: C(69,5) = 11,238,513 sets of five white balls, times 26 Powerballs.
- Every draw is independent. Each combination has a **1 in 292,201,338** chance on every draw, whether it was drawn last week or has never appeared. "Never drawn" is a fact about history, not a prediction, and it does not make a combination "due".
- Picks generated here are **random samples** from the not-yet-drawn set. They are not forecasts, they carry no advantage, and no tool or model can raise the odds of a lottery draw.
- The site is **independent and unofficial**. It is not affiliated with Powerball, the Multi-State Lottery Association (MUSL), or any state lottery, and it is not a source of official results. Winning numbers should always be verified with a state lottery.
- Draw data is compiled from published results and **may contain errors**.
- Lottery play is for adults: 18+, or 21+ in some states. US problem-gambling help, free and confidential, 24/7: 1-800-GAMBLER.

## Data

- [data/draws.json](https://powerballchecker.com/data/draws.json): every published draw since 2015-10-07 as `[date, w1, w2, w3, w4, w5, pb]` rows, plus an `updated` date and a `count`. This is the only data the site needs, and it is regenerated automatically after each draw.
