bowling game played on a standard tenpin lane with smaller pins and balls. Duckpins are 9.4 inches (23.3 cm) tall. The ball that is used to knock the pins down is a maximum of 5 inches in diameter and 3 pounds 12 ounces (1.7 kg) in weight, and it has no finger holes. Three balls may be rolled in each frame of the 10-frame game. There is no bonus for knocking down all 10 pins with three balls. Other rules are similar to those of tenpins. A perfect game is 300, as it is in tenpin bowling
