Abstract: An interactive game is disclosed which may take the form of a board game, a hand held game or a yard game. It includes a series of printed circuits or devices which may be concealed within a playing surface and an electronic detector for the circuits. Easily as many as 8 or 16 different discrete device may be detected and distinguished. Stored messages associated with each device or combinations of devices is displayed or audibly reproduce the messages. This invention is also applied to interactive books and games which have multiple layers with superimposed pages or boards. Interference between superimposed pages or boards is eliminated by surrounding each concealed device with a conductive pattern which has no resonant frequency in the range of detection of the electronic detector or probe. Likewise, concealed devices are not located on immediately following pages or boards at the same location on the page. The method of manufacturing such interactive games or books is disclosed.
