Your favorite I Spy Memory Game in a take-along, travel-size version. All new cards for new memory and matching fun! Made your matches? Now solve the 5 new riddles. The game uses the classic I Spy photography of Walter Wick as the basis for two styles of play. Younger children can simply match the images on two different cards while older players can find the images that correspond to various riddles. New riddles versus the full-sized edition, but only about a third as many tiles.
