Ten-pin bowling Effectively, there are three kinds of marks given in a score; a strike (all ten down in the first ball), a spare (all ten down by the second ball), and an open (one or more pins still standing after the second ball). A strike earns ten pins plus the pins for the next two balls thrown. (For example, if a player got a strike then followed with a 7 and 2 in the next frame, the value for the strike frame would be 10+7+2, or 19; if the player got a strike followed by another strike the next frame and
Ten-pin bowling influence lane conditions and scoring. Establishing a Bowling Ball Specifications Task Force—comprising research engineers and volunteers from ball manufacturing companies—the USBC sought to better understand the motion of bowling balls using scientific research and data analysis. Test equipment included, but was not limited to, a robotic ball-thrower, a Computer Aided Tracking System ("Super C.A.T.S."), 59 reactive resin and particle bowling balls from various manufacturers, and eight lanes in a climate-controlled facility. The driving force behind the study was summed up by USBC Technical Director Neil Stremmel: "USBC is concerned that technology has overtaken player skill [as the primary factor] in
