In Hidden Treasures you have a set of legendary treasures you're seeking to find. Every player places one of these treasures face down on the table and all players begin to play Expedition cards in order to claim the treasures for their own. You know what you're after, but what are the other players after?? and can you beat them to it? Through clever card play and careful observation of other player's expeditions, maybe you can swoop in and get what they're after before they do!
