  • Patent number: 4779874
    Abstract: A relatively simple, easy to play oil exploration game includes a rectangular parallelepipedic casing with a bottom drawer in one end thereof for carrying the game pieces. A horizontal bottom wall extends between the sides and ends of the casing defining a cover for the drawer. A plurality of partitions or panels are removably mounted in the open top of the casing. The top surface of the uppermost panel defines a playing surface. Each panel has a plurality of spaced apart, vertically aligned, circular openings defining oil wells. Irregularly shaped obstacles defining wet drilling locations or oil-containing wells are slidably mounted on the bottom wall and on the partitions beneath the uppermost panel. Simulated derricks of varying lengths are insertable into the top wall openings to simulate the drilling of wells and indicator pegs are subsequently insertable into drilled wells to indicate the presence or absence of oil.
