Qwirkle

The abstract game of Qwirkle consists of 108 wooden blocks with six different shapes in six different colors. There is no board, players simply use an available flat surface.

Players begin the game with six blocks. The start player places blocks of a single matching attribute (color or shape but not both) on the table. Thereafter, a player adds blocks adjacent to at least one previously played block. The blocks must all be played in a line and match, without duplicates, either the color or shape of the previous block.
