Inside One of the Most Comprehensive Lottery Datasets Anywhere
1.17 million draws, 286 games, 11 countries, back to 1978 — cleaned, normalised and refreshed daily. A look at the warehouse behind PatternSight.
Most lottery sites show you last night's numbers. PatternSight is built on something deeper: a maintained warehouse of over 1.17 million draws spanning 286 games across 11 countries, with history reaching back to 1978. It is refreshed every day, not scraped once and forgotten.

Cleaned, not just collected
Raw lottery feeds are messy — inconsistent draw-time labels, matrix changes mid-history, stray values. The warehouse normalises all of it: each draw is mapped to a canonical game configuration with a known number pool, so a frequency or gap analysis is computed against the right matrix rather than a smudged union of eras. That normalisation is what makes cross-game comparison possible at all.
Depth that enables analysis
On top of the draws sit derived layers: per-number frequency and gap digests, chi-squared calibration, and — newly — 457,000 advertised jackpots and 334,000 full prize breakdowns. Every chart in these articles is drawn live from that stack. The breadth is the point: it is hard to ask a question about lottery history that the warehouse cannot answer.
