My son who is 9 really enjoyed the game. He zipped through it in two days. The only issue he had (and consequently we as parents had) was that the graphics were so tiny it was hard to spot some of the differences. Overall, it was fun.
This is a fun game for all ages. It is the same Waldo that we all grew up with. The game is challenging at times when you can't find certain objects. The only drawback is that once you know where everything is, it doesn't become challenging anymore. I finished the game in a few short hours and feel satisfied. it's not one of those games you keep playing over and over.
