  • Patent number: 4496149
    Abstract: There is disclosed a game apparatus employing a container having located therein an electronic circuit capable of emitting a repetitive audio signal of a controllable volume and repetition rate. The container includes a compartment in which a prize or award is placed by the players. The container is then hidden by one of the players who selects the repetition rate and volume to thereby cause audio signals to propagate. The participants then attempt to locate the container in response to the emitted signals and the first participant who finds the container has access to the prize. The degree of difficulty is determined by the volume and repetition rate of the signal as controlled by the player hiding the same.
