The game board consists of 16 cells. Each cell contains between 1 and 4 puzzle piece. The puzzle pieces are made from one of 4 shapes: square, circle, star or triangle. Each shape can be colored red, blue, green or orange and be plane, checkered, vertically striped or horizontally barred.

The aim of the game is to match 4 puzzle pieces. Each of the 4 puzzle piece types must either match or be uniquely different. If 4 red pieces are chosen the color component is satisfied. This is also true if each of the 4 chosen pieces are all different colors.

Eg:
4 red plain stars
4 blue striped stars
4 green checkered stars
4 orange barred stars.

Each of the pieces chosen has 4 shapes, the shape is a star and there are 4 different colors with 4 different patterns. This is a valid 4 piece match.
