The levels in "Jewel Quest III" are set in several locations around the world and include silver, hidden and gold quests. The puzzle types differ by region, and one of the challenges is to discover the requirements of the hidden quest, which aren't revealed in advance. You can solve the hidden quests while you're working on the silver quests, or you can return to a region after you've completed the silver quests. You have to complete both the silver and the hidden quests for each area before you can move on to the gold quests.
