About
Data Sources
Source categories, purposes, limitations, and correction paths for Hindsight Games games.
Yearbook
Yearbook uses Wikimedia On This Day material and event-specific articles as research inputs. These are reference sources, not an endorsement or partnership. Source pages can change or simplify history; a player can use the corrections process to question a clue.
Roster Relay
Roster Relay uses league-specific player and team-season records to apply its connection rule. Sports records can differ on transactions, roster status, franchise names, and season coverage. The shared team-season shown by the game is the rule for play, not a claim of league endorsement.
Names and rights
