Very little educational value in this title. My daughter was bored after about 15 minutes. The whole underlying game is poorly planned and very disjointed. It was slapped together quickly to cash in on the name. The background music was the best part.
For this price, perhaps it will kill a rainy afternoon and get your kid smiling. But don't expect much after that.
I would highly recommend the I Spy series (only two now). They are much more engaging and kids get a sense of accomplishment AND learn in the process.
Oh and if you have a mac, forget it. We couuldn't get past the start menu. We have PCs in the house - it was fine on them. But don't waste your energy if you are mac only.
