This is one of the best computer games that my son has ever played. He can't get enough of it. He's just starting kindergarten, so many of the activities in the game reinforce what he is learning in school. Don't pass this game up! I actually enjoy playing it with him, and not many games suitable for his age can fit that claim.

I am a pediatric occupational therapist who used this game as a fun way to develop eye-hand coordination, visual perception, thinking, and reading skills. They were so motivated! Unfortunately after you "win" the game that is all there is; not another more challenging level to explore.

My son had loved the "I Spy Junior" game so I thought he might enjoy trying this challenge, recommended for ages 6-10. He's 5 but a very strong visual learner with great memory skills. The beauty of this game is it not only plays to his strengths but encourages building lesser skills with words on many levels. My favorite aspects: beautifully detailed graphics, a fun laboratory animation with 7 ghost experiments, and the concentration games which are a challenge at many levels. You get the sense that the creators enjoyed making this product. I find the best children's computer games (eg. Learning Company's Cat in the Hat series) reach parents as well making shared learning opportunities a joy!

Santa brought this game for my 6 yr. old for Christmas. She and I and her 3 1/2yr. old brother opened it the day after Christmas. It is very interesting with 10 rooms to explore and 26 riddles to decipher. After completing each riddle, you're given a piece to the final puzzle which in turn instructs you how to finally get out of the mansion. My daughter stuck with it for the first 13 riddles, and suprisingly my 3yr. old wanted to keep playing until the end. We received the "certificate of completion" that very day. When we signed back on to play a "new game", we were soooo disappointed - there isn't any new game. Same 26 riddles to solve. We'll have to wait a year or so, in the hopes that we'll forget where everything is. (Or just give it to all our neighbors, family, shool chums etc.). Obviously, the I Spy books have limitations, but the software could and should give many additional games/levels.

Purchased for my grandson's 5th birthday. Incredibly clever, well designed, plays without a hitch on iMac. He played for over 2 hours the first time out of the box and is still loving it. The adults are fighting over a turn.
