Bowling refers to a series of leisure activities in which a player rolls or throws a bowling ball down a lane. In indoor bowling, the target is usually to knock over pins. In outdoor variations, the aim is usually to get the ball as close to a target ball as possible. The indoor version of bowling is often played on a flat wooden or other synthetic surface, while outdoor bowling the surface may be grass, gravel or a synthetic surface. The most common types of indoor bowling include ten-pin, nine-pin, candlepin, duckpin and five-pin bowling, while in outdoor bowling, bowls, bocce, pétanque and boules are popular. Today, the sport of bowling is enjoyed by 95 million people in more than 90 countries worldwide.
There are many forms of bowling, with one of the most recent being ten-pin bowling, also known as the norm. The earliest most primitive forms of bowling can be dated back to Ancient Egypt and the Roman Empire. Indeed, about 2,000 years ago a similar game evolved between Roman legionaries: it entailed tossing stone objects as close as possible to other stone objects (this game became popular with Roman soldiers, and eventually evolved into Italian Bocce, or outdoor bowling).
The first standardized rules for pin were established in New York City, on September 9, 1895. Today, bowling is enjoyed by 95 million people in more than ninety countries worldwide and continues to grow through entertainment media such as video games for home consoles and handheld devices.
Bowling is an anaerobic type of physical exercise, similar to walking with free weights. Bowling helps in burning calories and works muscle groups not usually exercised. The flexing and stretching in bowling works tendons, joints, ligaments, and muscles in the arms and promotes weight loss. While most sports are not for elderly people, it is possible to practice bowling very well at advanced ages.
Like any other physical activity, warming up helps to prevent injuries. Bowling balls are heavy with varying weight ranges; to avoid back and wrist injury, they should be picked up with both hands. It’s also recommended to bend one’s knees while picking up bowling balls to avoid back injuries. Most bowling ball return mechanisms use a power-lift that includes a spinning wheel, and it is recommended that bowlers should keep their hands clear of it. Bowlers should also warm up their fingers before inserting them into a bowling ball, to ensure that their fingers do not get stuck in the ball.
Even in small ball bowling, balls should be picked up with one hand on each side of the ball — small balls return to the rack with enough force to smash fingers.
It is very common in bowling to warm up in other sports by stretching the arms and legs. Some ways bowler stretch is by using the bowling ball as a sort-of medicine ball. They pick up the bowling ball and put the ball behind their head and stretch their arms. Normally bowlers squeeze the bowling ball. They also stretch their quadriceps by lifting their leg behind their back. "A warm up should begin with some light activity to increase blood flow to the muscles" ("Bowling stretches," )
It is imperative to keep the soles of bowling shoes dry. If the bowling shoe sole gets wet, it can stick like glue on an approach and result in the bowler suffering a wipeout or blown knee. The most common causes of wet bowling shoes tend to be spilled beverages, drips in washrooms and near concessions, and snowmelt or rainwater tracked into the bowling center. Outdoor footwear should be removed at the bowling center entrance. All spills should be reported to bowling center staff and cleaned immediately. A shoe cover is sold in most pro shops for bowlers who still want to wear bowling shoes while walking around the alley, in the washroom etc. Removable soles are sold with higher end bowling shoes to combat when a bowling shoe does get wet.
The lane surface carries a high amount of oil (lane conditioner) and is extremely slippery. A bowler should never cross the foul line at the approach. Only authorized personnel should step past the foul line, even if it is to pick up a loose item that fell onto the lane.
The most common bowling is ten pin bowling. In ten pin bowling, matches consist of each player bowling a "game". Each game is divided into ten "frames". A frame allows a bowler two chances to knock down all ten pins. The number of pins knocked over in each frame is recorded, a running total is made as each frame progresses, and the player with the highest score in his/her game wins the game. Scores can be greater than the actual number of pins knocked over if strikes or spares are bowled. A "strike" is scored when a player knocks down all pins on the first roll in the frame. Rather than a score of 10 for the frame, the player's score will be 10 plus the total pins knocked down on the next two rolls in the next frame(s). A "spare" is scored when all pins are knocked down using both rolls in the frame. The player's score for that frame will be 10 plus the number of pins knocked down on the first roll in the next frame. A player who rolls a spare or strike in the last frame is given one or two more rolls to score additional points, respectively.
Two consecutive strikes is known as a "double" (also known among older bowlers as a hambone, prior to Pro Bowling Association/ESPN announcers changing it). Three consecutive strikes is known as a "turkey." Four consecutive strikes is known as a "hambone" (PBA announcing in 2009/2010) or "four bagger". Five consecutive strikes is known as a "five bagger", "dropping the nickel", or "Yahtzee" (PBA). Six consecutive strikes is known as a "six-pack" or "Six bagger". Seven or more follow the "-pack"/"bagger" rule, or is simply called (number of strikes) in a row. As of November, 2012, three consecutive spares is known as a "chicken." A perfect game consists of 12 consecutive strikes, one for every frame and two more on the extra rolls in the 10th, and results in a score of 300. A clean game is filling every frame with either a spare or a strike. In many forms of indoor bowling (specifically ten-pin, candlepin, and duckpin), the highest possible score is 300. In five-pin, the highest possible score is 450.
A common variation of the game is no-tap, a form of bowling where a specific number or more pins knocked down counts as a strike. Nine or eight pin no-tap is most often used. No-tap in five-pin awards a strike if the first ball leaves one of the corner pins.
There are typically two different ways to roll a ball down the lane.
There are three different types of styles used when releasing the ball onto the lane. The three styles are the stroker, cranker and tweener styles.
Bowling balls vary, depending on the type of bowling game. Ten-pin balls are large, up to 27 inches in circumference (approximately 8.59 inches diameter), and have as many as twelve holes, typically three holes. The balls come in various weights from 6 to 16 lbs, with the size and spacing of the finger holes often smaller on lighter balls to accommodate smaller hands. Different kinds of balls are available for different styles of bowling. There are balls for hook shots and balls for bowling straight. The bowling balls meant for hook shots have different core shapes and different chemical covers. There are a few types of chemical covers that allow a bowling ball to hook more. One of these types of covers is a resin cover. This resin cover is designed to move and absorb the oil on the lane to create a path for the bowler where there is less oil, increasing the amount of hook of the bowling ball. Balls for other games vary, e.g., candlepin balls which fit in the palm of the hand need no holes. Unlike most sports, the ball can be different weights based upon the player.
All bowling centers provide bowling balls (house balls) - their usage is included in the bowling fee. For ten pin bowling, the center will provide a fleet of house balls in varying weight and standard grip sizes while idle lanes have empty ball return racks. Customers that use house balls will pick a ball that fits from the house ball fleet and place it on the ball rack at the designated lane. When done, the customer returns the house ball to the house ball racks. In small ball games, each ball return contains a quantity of house balls — usually in at most one or two color patterns.
Bowling shoes are designed to mimic any style of flat shoe from regular dress shoes to athletic shoes. The sole of the non sliding foot is generally made of rubber to provide traction, while the sliding foot's sole is made of a smooth and flat material that allows a bowler to slide into his release with a rubber heel to allow for braking. Rental shoes are typically leather and rubber on both feet for durability. These shoes can be bought, but most casual players rent the shoes each visit to a facility. Players must be very careful while wearing them that the soft material does not get wet or excessively dirty; if it does get wet or dirty, it will not slide properly, and could damage the approach surface.
Depending on the bowling center, shoe rental may be included in the cost of bowling or be added as a separate fee. To discourage theft, bowling shoes are often painted in highly distinctive patterns so that anyone who does steal them will not be able to wear the shoes in public without making the theft obvious.
A bowling guard is a metal wrist support to attain a certain angle to the wrist when releasing the ball; to hook the ball. There are different types of hand guard, including those with a full metal finger design and ones with an uncovered portion for the middle and ring fingers. There are also wristguards. They allow a bowler to keep their wrist locked into place to generate revolutions on a ball or assist with position and/or weak wrists.
Traditionally, personal bowling balls are carried in special zippered bags, along with shoes and a polishing cloth. Some bags are only large enough to fit shoes, while others can accommodate multiple balls, resembling roller bag luggage.
A bowling center is a facility that is equipped to play the game of bowling. Bowling centers usually have at least two lanes with larger centers having over 80 lanes. Depending on the building, lanes may be laid all on one floor, across multiple floors, or a setup with a group of lanes facing one direction and another group of lanes facing another direction. Bowling lanes are laid out in married pairs with each pair sharing a ball return rack, automatic scoring console, and in some cases a bowler seating setup. Weekly league sessions are normally contested on one married pair of lanes with equal play for each participant on each lane. In a tournament, one game will be played on a married pair of lanes and bowlers will change to a new pair of lanes after every game.
The lanebed is built from either wood or phenolic. A wood lane uses maple for pindecks, the ball impact zone and the approach while pine is used for the second half of the lane after the impact zone. The measurement from the foul line to the center axis of the head pin is exactly sixty feet. In tenpin, the pins are either Surlyn-coated maple or a plastic composite. For small ball bowling, all pins are now made of plastic composites. The pinsetter varies by game, but have two foundations — string and free-fall. Most ten-pin, candlepin, and duckpin centers are free fall while five-pin and soft belly duckpin centers are dominated by string pinsetters. String pinsetters have a lower operating cost. The ball return consists of a ball tray and an up-ramp. Most ten pin centers and some small ball centers use a power lift to raise the ball to the tray.
A bowling center requires a lot of space. A single lane requires a footprint of about 620 square feet including the lane bed, gutters, pit end, pinsetter, ball returns, and approach area. This does not include space for seating, party rooms, arcades, the concourse, kitchen, administrative areas, fire safety systems, and other building requirements.
Another form of bowling is usually played outdoors on a lawn. At outdoor bowling, the players throw a ball, which is sometimes eccentrically weighted, in an attempt to put it closest to a designated point or slot in the bowling arena. Included in the outdoor category:
Bowling is often depicted as a group date, teen outing, and blue-collar activity.
The sport has been the subject of a number of "bowling films", which prominently feature the sport of bowling. Examples include:
Bowling is an important theme in other films, as well.
Technological innovation has made bowling accessible to members of the disabled community. The IKAN Bowler, a device designed by a quadriplegic engineer named Bill Miller, attaches to a wheelchair and allows the user to control the speed, direction, and timing of the bowling ball's release. The name comes from the Greek work "ikano", which means "enable".
