Quarto- The Game of Fours

Quarto is one of the most elegant strategy games ever designed. Simple to learn, endlessly deep. 16 unique pieces. 4 attributes. 1 winner. Each piece is defined by four binary attributes — size, color, shape, and fill. On your turn, you choose a piece for your opponent to place. The catch: you might just be handing them the winning move.
