Patent US 6,789,797

A mystery role playing game system optimized for children suitable in terms of level of difficulty for all participants; that does not require any participant to play the role of a criminal and/or “bad guy”, that allows responsible supervision of the course of the game, that provides positive social rewards to a selected individual (for example a particular child whose birthday party is the occasion for the game), that provides a carefully structured format for progression of the game, and which includes one or more modest “physical” challenges such as hunts for treasure and/or clues. A central “detective” character may supervise other player's rounds, and non-player supervisors may also supervise revelation of each character's clues. Non-player characters may take the negative roles (such as suspects), and the central character may have sufficient information to solve the mystery at the end of the game.
