Guess Who? Guide: Rules, Questions, Guessing & Strategy
Guess Who?
Ask yes-or-no questions to eliminate faces and identify your opponent’s mystery character before they identify yours.
Guess Who? is a two-player deduction game built around binary questions. Each answer should remove as many possibilities as possible without risking a premature final guess.
Why it matters
The game’s most common questions concern what counts as a legal yes-or-no question, when a player may guess and the consequence of a wrong guess.

Rules overview
Each player secretly selects a mystery character. On your turn, ask a yes-or-no question about the opponent’s character and fold down faces ruled out by the answer. When you think you know the character, make a guess. Under Hasbro C2124, a wrong final guess loses that game.
Key decisions
The best questions split the remaining candidates as evenly as possible. Questions that eliminate only one or two faces waste information.
