The Game of Logic

The Game of Logic is a book written by Lewis Carroll, published in 1886. In addition to his well-known children's literature, Carroll was an academic mathematician who worked in mathematical logic.

This Game requires nine Counters--four of one colour and five of another: say four red and five grey. Besides the 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: take Cricket, for instance, which requires twenty-two. How much easier it is, when you want to play a Game, to find ONE Player than twenty-two. At the same time, though one Player is enough, a good deal more amusement may be got by two working at it together, and correcting each other's mistakes.
