All 27 topics, 1,094 sourced records.
Plain Game draws its questions from 27 topics. Each topic page lists every record, the unit, the frozen snapshot, the source and the recent daily flights that used it. The catalog is the same one used for scoring, not a separate marketing list.
How a daily flight chooses topics
The daily question order is deterministic for each New York date. A flight uses seven distinct topics from different domains, with five name rounds and two numerical estimates. A Golden Round is chosen once per flight and doubles that round’s points. The catalog is ordered and frozen so every player sees the same questions for the same game day.
Practice is different: you can choose one topic, one question type and a pace. The practice setup opens before a clock starts. A topic page always links to the complete record table and the source, so you can check a value after a reveal.

Records, not unique entities
The catalog contains 1,094 records across 27 topics and 15 domains. The largest topic is Pokémon weights with 151 records; the smallest is Mountain heights with 8. A record is a named row with a value, unit and source; some names share a value, and some topics contain several measurements for the same broad subject. We do not describe the catalog as 1,094 unique things, and a tie in a name round is expected rather than an error.
Every topic has a defined scope and snapshot. A current live statistic can differ from the snapshot used for scoring; the snapshot is the value every player sees. See source attribution and licences for the full notices and correction path.
The catalog is not a difficulty ranking, a list of guaranteed future questions or a promise that every topic appears equally often. The daily order is deterministic for a date, and practice can choose a topic directly. Use the record counts and ranges here to decide what to study, not as a prediction of the next flight.
Practise a topic
Choose a topic to open a pre-filled practice setup. You can change the pace, question type or difficulty before starting. Practice does not replace a daily attempt or change a daily score. The table above is also the fastest way to audit the catalog: every topic has a stable URL, a record count and a latest-use date. Every row opens a topic page with the full record table, unit, source and recent daily use; the hub itself stays a compact index, and no topic is hidden. It is a starting point for the full pages, not a substitute for them.
