a data observatory

Decades of draws.
No predictions.

DrawData turns public lottery history — Pick 3, Pick 4, and Powerball — into an interactive, honest data instrument. Watch frequencies converge, gaps wander, sums settle into a bell. Test your favorite “system” in the Formula Lab and see, with your own eyes, why randomness is randomness.

Principle

Descriptive, not predictive.

Every chart in DrawData shows you what has happened. No chart, ranking, or tool here is designed to tell you what will. Lottery draws are independent and random — the past does not pull on the future.

Centerpiece

The Formula Lab.

Compose a transformation rule from the previous draw — shifts, mirrors, anchors — and backtest it across every consecutive draw. See the empirical hit rate beside the chance baseline, side by side. Spoiler: they match.
