So far, so good! He loves trying this puzzle out for minutes at a time, multiple times a day. It has a small silver ball inside that you must follow the numbers through a path, twisting and turning the Perplexus ball to keep the small silver ball on it's path. I have played with it a number of times now myself and yet to have mastered it either. Definitely lots of excitement trying to see who can get the furthest along without the silver ball dropping out of it's path!
This puzzle ball was definitely a hit in our household! Like Perplexus on Facebook and follow them on Twitter for more information. Then, take a look at this video to see it in action:
