Rulebook

The rulebook is the printed booklet that walks you through setup, turn structure, and every rule needed to actually play. Heavier games often split it in two: a short quick-start that gets you through your first game fast, and a fuller reference for the edge cases and exceptions you’ll only hit once you’re a few sessions in.

A rulebook is a decent early clue to a game’s complexity rating — flip through it before you commit to a night and you’ll get a real sense of how much explaining is ahead of you. It’s also one of the easier pieces to misplace between plays, small and paper-thin next to a box full of boards and tokens, which is exactly why it’s on the component list a rental gets checked against.
