Ten-pin bowling back row, then three, then two, and finally one in the front at the center of the lane. To ease communication, pins are numbered one through ten, starting with "head pin" in front, and ending with ten in the back to the right. Because of the spacing of the pins and the size of the ball (about in diameter), it is impossible for the ball to contact all pins. Therefore, a tactical shot is required, which would result in a chain reaction of pin hitting pin in a process called "pin scatter". In an ideal shot for a right-hander, the
Bowling pin Canadian fivepins are between duckpins and tenpins in size, but have a thick, inch-wide rubber band around the widest part of the pin to increase pin action when struck.
