Every lottery number Mega Millions pair ranked by co-occurrence across 1,900+ draws, with gap analysis against the random baseline and the honest statistical verdict.
Full draw-gap analysis for all 69 Powerball white balls and 26 red Powerballs, with the independence verdict: does a longer gap raise a ball's odds of hitting?

Chi-square analysis of approximately 1,500 Powerball draws tests whether numerology's canonical lucky numbers (1, 3, 7, 9, 11, 22, 33) have any statistical edge. The result: χ² = 2.44, p = 0.875 — they don't.
Pick 3 live draw archives vary wildly by state: some publish decades of CSV data, others nothing. Here's how to find, validate, and actually use what exists.
We mapped every Powerball jackpot win since 1992 to reveal the rollover-streak distribution — and where the current $173M jackpot sits in the historical record.
