This is a really cool toy. It comes with lots of floor and barrier pieces to create many different paths for the mouse. The cards are really handy for younger children to make mazes for the mouse. The floor pieces are a little too hard for my youngest to connect by herself, so this could make some children frustrated. I also wish it came with some little bags for the smaller pieces for storage, especially with the hole in the box. This is a great toy for multiple age children to play with together. This product was received for free from house party to test out with my children.
