I have read some reviews that say this game doesn't work properly- I am not sure what's going on with theirs, but my son(8 years old)can put this together perfectly and it traps the mouse 99% of the time. The goal of this game is not to put it all together at first, but to do so as you move throughout the game one piece here and there. I have had ZERO broken or flimsy pieces. We have taken it apart and put together multiple times with ZERO issues. The thing works like a well oiled machine. This game was for my 8 year old. When we received it, it took me to my childhood. Worked like a charm as I remembered it- Great game.
