Keno Game Catalog: Open Data Downloads
Download a source-backed catalog of official Keno lottery games, not winning-number results. Compare operators, jurisdictions, number pools, draw sizes and schedules, then follow each record's official rules and results links. JSON preserves normalized records and field assertions; CSV provides a flattened table.
What the dataset contains
The catalog describes published lottery offerings: their operators, jurisdictions, regulatory-authority relations, documented selection and draw mechanics, schedules, and official website, rules and results URLs. Each assertion can be traced to reviewed evidence by its source identifiers.
JSON keeps normalized entities, relationships and field assertions. CSV is a flattened view of the same published offerings. Unknown values are not estimates; read the field dictionary and assertion example before treating a value as established.

Ways to use the catalog
Build a country or operator directory: filter CSV rows by country_code or operator_id, then use game_slug to find the corresponding game page.
Compare documented Keno formats: group offerings by number_pool and numbers_drawn. Check picks_allowed and the official rules before choosing inputs for an exact-match probability calculation.
Audit provenance and freshness: follow source_ids from JSON assertions to the evidence registry, and inspect last_reviewed_on and verification_status in CSV. A review date records our source review; it does not guarantee that an operator has made no later change.
