Second puzzle by Samuel Cook. Minimal, clean and elegant. Goal: pack all 4 blue pieces flat inside the frame so nothing sticks out. Samuel's sequel to Jigsaw Traffic uses 4 pieces and a sneaky square frame yet again. This time, the pieces are geometric shapes. How would they interact with each other? That is the question! What's special about Turbulence? Deceptively simple - hard in practice Develops 2D spatial reasoning and logic Compact and satisfying to solve Designed by Samuel Cook
