I first played Mousetrap when I was a kid.  It was always so much fun putting all the stuff together that would you allow to take a metal ball, start it at the beginning of this contraption that you put together.  It would roll this way and that way and cause all sorts of things to happen such as making someone jump off a diving board into a bucket but ultimately;  the goal was to catch the mouse in the trap.  This is a game that has stood the test of time and provides fun for all ages.
