"Guess Who?" is a two-player board game where players try to identify each other's mystery character. Each player has a board with a set of characters, each with distinct features like hair color, glasses, or hats. Players take turns asking yes-or-no questions to narrow down the possibilities. The goal is to be the first to correctly guess the opponent's character. The game encourages critical thinking and deductive reasoning as players eliminate options based on the answers they receive. It is suitable for children and families, making it a popular choice for game nights.
