Midnight Castle review

Midnight Castle is Big Fish's free hidden object game and the gentlest option here. You explore a castle full of royalty, dragons and trolls, search scenes for magical items, and craft relics, potions and poisons from what you find. New locations open with coins and diamonds, which you can earn or buy, and Facebook friends can swap gifts and fill each other's wish lists. The App Store rating is 4+, the lowest on this list, which makes it the safest pick for children or a mixed-age household. It ranks last for capabilities because it is English only, lists fewer search modes than the leaders, and leans on friends for gifts. Diamond packs start at $0.99 and go up to $39.99. Big Fish is better known for paid hidden object adventures, which were left out here because they are not free. We compared documented features and published prices.
