Tenpin bowling is a sport in which a player (bowler) rolls (bowls) a bowling ball down a narrow, straight, flat, wooden or synthetic €˜lane€™ with the object of scoring points by knocking down as many of the ten pins as possible set in a triangular formation at the end of the lane.

A game consists of 10 frames with the bowler having a maximum of two attempts to knock down the 10 pins in each frame.

The maximum score for a game of 10 frames is 300.
Bowlers compete with each other (singles) or in teams of two (doubles), three's (trios)

or four or five person teams.

Bowling lane
The most common type of lane is wood. Synthetics are becoming more popular and some lanes are a combination of wood and synthetic. The lane is 60 feet from the foul line to the centre of the headpin.

The approach is a minimum of 15 feet long. Measured from the foul line, a maximum of seven guides may be embedded in or stamped on the approach at each of the following points: 2-6 inches; 3-4 feet; 6-7 feet; 9-10 feet; 11-12 feet; and 14-15 feet. Each series of guides shall be parallel to the foul line and each guide shall be circular in shape and shall not exceed ¾ inch in diameterThere is a large dot embedded in the middle of the approach at 12 1/2 feet (3.8m )with two dots either side, five boards apart, that are used for lining up the feet of the bowler. Some centers have an extra set, making a total of seven dots.

Foul line
The foul line is at the start of the lane and measures 3/8 inch to 1 inch wide. There are dots embedded into the approach side of the lane situated at five boards apart and used for lining up and targeting.

The boards
There are 39 to 42 boards on a lane. The first arrow from the gutter is the 5 board, the second arrow is the 10 board etc. and the middle arrow is the 20 board.

The dots
At a point 6-8 feet beyond the foul line and parallel thereto, there may be embedded in
or stamped on the lane a maximum of 10 guides.  They are located from the right from the gutter on the 3, 5, 8, 11 and 14 boards. It is the same from the left side.

The pin deck
The pins are located within a 36 inch equilateral triangle, with each of the pins aligned

12 inches apart center to center.

Bowling pins are made from hard maple and when shaped, coated with a white plastic. The weight for all pins is 3 pounds 6 ounces  toˆ’ 3 pounds 10 ounces.


If you are in a league, show up in time for practice.
Don't use another bowlers equipment without permission.
Respect all equipment as if it was your own property.
Keep one ball per person on the rack.
Be prepared to take your regular turn on the lanes.
Be ready to bowl when the pins are set. Do not bowl until the pin setting machine has completed its cycle and the sweeper bar is raised, otherwise you may damage the ball or machine and you could be charged for its repair.
Stay on your approach while delivering the ball. Step back off the approach after making each delivery.
Try not to take too much time on the approaches before delivery.
Always stay behind the foul line.
The bowler on the right should bowl if both reach the approach at the same time. Stay off the approach while you wait.
Excessive "lofting" hurts your game and damages the lane.
Keep food and drinks in designated areas. Spilled liquid can create problems for all bowlers.
Play to win but be gracious in defeat. Bowling is both a sport and a recreation that you should enjoy regardless of the score. Be a good loser as well as a good winner.
Save the kidding for later. Boasting, bragging, heckling or griping have no place on the lanes.
We all get emotional, just try and not let them interfere with others while they are bowling.
Refrain from using abusive language or obscene gestures.
Control your emotions on the lanes. Kicking the ball rack does not help anyone.
