The KeyForge Master Rulebook (MRB) is the comprehensive rules of play for the game of KeyForge. It is the game’s most authoritative source and contains a detailed glossary, official errata, frequently asked questions, and a timing chart. It is primarily a reference document to help players find answers to specific questions. We update this rulebook periodically as new cards sets are released and as new questions arise about how to resolve various card interactions that occur during games.

Note that if you’re new to KeyForge, the best ways to learn how to play the game are to read Learn to Play KeyForge and to watch our video tutorial.
