This puzzle is actually just one long piece. The individual cubies are connected by strings that allow the pieces to rotate relative to each other. Some pieces are connected in sequence, while others are connected at 90-degree angles to each other. The objective is to open up the snake arrangement, then return it to the checkerboard cube shape as shown.
