I got the game to review with my 6 year old twin girls' and they love the game. It's a great way to teach them the general concept of programming in an easy way. It's very easy to set the commands for the mouse and it works very well. The girls had to "program" the mouse to go to the cheese and set up a maze that it had to go through. The only thing I found a little annoying was having to use the cancel button to erase the memory between "puzzles" but it's necessary to start anew, just not that easy to remember for the kids. There are ten activity cards included in the game. The cards contain twenty problems and help you get started with an initial setup of each problem. You then place walls and tunnels on the board and then the mouse has to follow your path. I think this game is a great introduction to programming and getting kids interested in how games work and are created instead of just playing them.
