"The Game of Logic" by Lewis Carroll is a book published in 1886. Using a playful board game with colored coins, Carroll transforms abstract logical propositions into tangible puzzles. Players place red and gray coins across quadrants representing variations of statements like "Some fresh cakes are sweet." The system progresses from simple two-part diagrams to complex three-dimensional problems, teaching syllogisms and logical reasoning through interactive play. This mathematical work reveals Carroll's lesser-known identity as an academic logician.
