Abstract
A new treasure hunt game is played by concealing magnets in a game board and passing a detector assembly in a path over the game board to provide a concealed stored indication, retrievable later, that the detector's path has intercepted a concealed magnet. The detector assembly includes a pivotable indicator having two gravitationally stable positions, and magnetic means in the indicator for pivoting it from one stable position to the other stable position as the magnetic field of a concealed magnet is encountered. The indicator remains in its second stable position after once passing over a concealed magnet to store the indication. A housing with a retractable cover encloses the indicator, and a cushioned stop for the indicator absorbs noise and vibration, so that an indication is hidden from a player moving the detector assembly until a selected juncture in the game.
