This game will drive you crazy and soon. It is very simple to play. All you have to do is start the timer and then put all of the little yellow geometric pieces in the correctly shaped slots before time runs out. If you don't get them all in in time, the board "pops" and the pieces you do have in go flying everywhere.
It can be very frustrating, and it can be downright impossible for younger children, though it is good for learning hand-eye coordination. The pieces are relatively small and can easily get lost, especially when they fly out of the board.
The kids I know that have this game tire of it very quickly once they get the hang of it. For an extra challenge, you can turn the timer only halfway.
I'd say the worst part of this game for me is trying to find all of the little pieces after they've popped out of the board. They are very small and can get under the couch easily or get grabbed by the dog. It can become another game in itself trying to get them back. The other thing I don't like about it is the constant ticking of the timer on the board. I already feel silly putting the shapes in the wrong place and that makes it extra nervewracking.
