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.

iOS with all the depth the game deserves.
