The I Spy books are well regarded for their beautiful artwork, in which you must find an impressively large number of camouflaged objects. While the concept translates well to digital platforms, the DS screen is a bit small for it; you need to scroll around to see the whole picture, which takes a little away from the experience. Once kids have solved the puzzles, there's no real reason to go back to them; luckily, riddles and several minigames extend the life of I Spy Fun House.
