Game of Logic

Lewis Carroll's Game of Logic was initially published as a book with two boards and a set of cardboard counters. The game employs Carroll's bilateral and trilateral diagrams to solve logic puzzles in the book.

In the preface Lewis Carroll remarked:
Besides nine counters, it also requires one Player, at least. I am not aware of any Game that can be played with less than this number: while there are several that require more.
