Description: Hi-Score Bowling Alley, United, 8/57, 3" balls, 11 or 14 foot lengths (a 4 foot section could be added to 14 foot base game to get 18 feet), ball does not hit pins but instead travels beneath them and hits lane switches. Note game does *not* have gutters, so kids really love this game (no gutter balls, the ball can bounce from side to side). Adults of course find this less challenging.
