house shot pattern
When you walk into your local bowling alley and start bowling you are most likely bowling on a house shot. The house shot is the regular oil pattern that is put down on the lane for open bowling. This is usually 18mL of oil and is a very simple shot for experienced bowlers. It becomes very easy to predict what your ball will do on a house shot and scores were becomeing very, very high. Because of these extremely high scores Sport Bowling was introduced in 2000. Sport Bowling is described below, but basically it is just more difficult oil patterns to help keep scores down and keep bowling about technical skill.
