We received a free ChatPack to test the Code and Go Robot Mouse Activity. Let me just say that my 7 year old son was not disappointed! The set includes pieces to make different mazes, a piece of "cheese", and a cute robot mouse. The mazes were difficult to assemble at first but got much easier with practice. The mouse has large, simple buttons which are perfect for little hands. My son's favorite way to play is the more advanced way without the base pieces to the mazes. He really gets a kick out of programming the mouse to travel around the floor to get to the cheese!
