Abstract: A game board simulating an oil well field. The game board has a hollow interior with a plurality of movable elements positioned therein. A plurality of holes are provided on the game board playing surface simulating oil wells and leading into the hollow interior. An oil well derrick has a plunger extendable through the oil well holes to contact the movable elements located therebeneath. A plurality of oil well properties are positioned around the periphery of the game board and arranged in a path to be followed by player tokens. The properties are grouped into families of properties. The playing surface is colored in different regions with each region associated with a particular family of properties simulating oil well fields associated with a particular property.
