As an adult who has purchased this game, I'm thinking one shouldn't have high expectations for things that give them hours of mindless fun. That's why I'm giving it 4 stars, instead of 3 or less. If you're looking for something that will hold your attention while you kill some time, or give your mind a bit of a rest, then this game is perfect. In fact, it can be rather addictive in that respect. I'm not one for complicated games, so personally, I love it.
I don't think a synopsis of the game is necessary (it's a game of "find the hidden object" - not too many ways to elaborate on that), so I'll just say that the graphics are nice, and I like how the lists of items to be found change each time. Some objects are easy to find, others take a minute to locate. I'd prefer it if the extra "challenges" (they're really not all that challenging, especially after you've completed the game once) in between the levels changed as well, but sadly, they don't.
My biggest peeve with the game, if I can really even call it a peeve, is how it ends. While cracking that particular challenge is fun (again, in the mindless way), not only is it vague about how you actually accomplish it, it's rather anticlimactic. I won't ruin it with details, but suffice it to say that if you're playing the game for the most appropriate reasons (see above), the fact that the ending is kind of ho-hum shouldn't be a problem.
I'd definitely recommend it for anyone who'd like something that will keep them amused as they kill some time, but if you're looking for something more exciting - or something that requires more a complex thought process - this isn't it.
That said, my nephews (who are 4 and 9) love it! So, if you're looking for something that just about anyone in the family will enjoy, regardless of age, then my recommendation increases tenfold. I'm not an expert in childhood development, but I'm sure it doesn't do any harm to kids when developing their hunting skills on an intellectual/visual level, and it would probably do their attention spans a bit of good, too.
