This sport is one in which a player brings a plastic ball that is rolled down an alley to 9 pins. The “ball” is smaller and lighter than US bowling, the ball may have two or no finger holes. The lanes are shorter than US bowling. The 9 pins (cones) are placed in a diamond shape on the alley. In most lanes systems the pins have a rope on top, to pick up the pins and replace then back in to the diamond shape for the next roll. In Germany there are four kinds of lanes systems. The game is played in 120 throws of 4 lanes. On each lane 30 throws. On one lane there are 15 throws on all 9 pins (full) and 15 throws so on till no pins are left (cleaning).
