BoardGameFYI is a free online encyclopedia for exploring the world of board games. Its database covers more than 10,000 games, alongside information on mechanics, categories, designers, and publishers. Visitors can browse these collections, compare games, explore game paths, and use guides, a glossary, and other tools to discover titles and understand how they play.

Its ratings use the BoardGameGeek weight system, based on community votes, and organize games into five tiers from Light to Heavy. Filters help users narrow choices by group size and complexity, while the Game DNA system supports discovery based on strategy depth, interaction, and replayability.

BoardGameFYI also explains common mechanics, such as deck building, worker placement, area control, and hand management, and offers guidance on choosing games and understanding expansions. Its information is sourced from BoardGameGeek and Wikidata. The encyclopedia is available in multiple languages, serving both casual players and experienced hobbyists seeking useful ways to explore and compare board games.
