Game: Secret Passages: Hidden Objects

While Secret Passages: Hidden Objects from Pocket Gems isn't the first free-to-play hidden object game on iOS, it is one of the prettier options available. This mystery adventure takes players through secret passages connecting different eras and great civilizations as a young girl tries to solve the mystery of her father's disappearance years before. Secret Passages has lots of charm, and lots of lovely hidden object scenes to complete, but it ultimately suffers from its free-to-play model.
