I received a free Chat Pack that included the Code & Go Robot Mouse activity set and absolutly love it. My children have not wanted to put it away since. At first it was a little tricky but after playing with it for about 10 mins my kids got the hang of it. I love watching them figure out the correct coding to help the mouse reach the cheese. It is very easy to assemble and take apart when trying a different maze. I definitely recommend this to play with your children
