From the publisher's Web site: Let Leonardo be your guide to the secrets of the ancient world and the great achievements of civilization. In this new trivia game, follow the path of the famed Templar Knights as you journey across five continents in your quest to crack a mysterious "code word." Each correct answer to one of 100s of multiple choice trivia questions reveals a new clue to the "code word." Categories consist of Genius and the Grail, People and Places, Faith and Fable, and Quest Curiosities. Players are dealt five cards, face up and one, face down. Each card features a word and a letter. The word on the face down card is a player's "code word." As players move around the board answering the multiple choice trivia questions, they are afforded the opportunity to trade and/or "steal" oppponents' or supply stack letter cards to replace their own stack of 5, face up cards, in a quest to form the "code word." Once players have formed their "code word" with their 5, face-up cards, they proceed to a central (Grail) square and attempt to answer a final question to win the game and complete their quest.
