This MB game comes with a plastic "board". Its size is dictated by the three randomizing discs embedded in its base, which are used to generate a new playing area every time (there are 1,728 (12^3) different setups possible).
You buy properties, drill for oil, link properties with pipelines so as to collect royalties and try to be the richest player. Event cards complicate matters. Drilling is resolved with a little rig whose plunger is pushed up if it doesn't go through the hidden disc; if it pushes through all three, the well is dry. Deeper holes cost more, of course.
Pipelines can be bought once you have 4 producing oil wells on a property; they reach across that property's boundary to another player's property, and are used to siphon royalties from him every turn. This is a clever mechanic that accelerates bankruptcy and keeps total playing time within reasonable limits.
Once all players but one are pushed into bankruptcy, the remaining one is the winner.
TULSA. The early 20s. The finest cattle country in the world. A ballin' squallin' boom town riding the crest of the golden tide of oil. Oil was still a game then. Made fortunes for some.
This game variant uses the normal KING OIL rules but a 28 card TULSA DECK is also used. The elements in the deck are from Tulsa (1949) starring Susan Hayward. A 20 sided die and two 6 sided dice are needed for this variant.
I enjoy how KING OIL works, so I made this for my own enjoyment of the game and the classic oil flick, Tulsa. The Tulsa cards do help alleviate some of the pure luck that can overrun unlucky players when just using the Wildcat deck.
