Requiring no reading from its players, Qwirkle is a simple-to-learn but stimulating game based around matching the attributes of the game play tiles. Players build rows and columns by placing tiles adjacent to tiles they share an attribute with (shape or color), and score bonus points if they can think ahead and put a tile down touching multiple other tiles. While the game is easy to understand, a good eye and quick thinking make Qwirkle challenging enough for a wide range of ages to play together.
