Scoring
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 match. 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. 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.
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.
