What is the highest handicap game in bowling?
There are three variables that affect a bowler's handicap: 1)
Their current average, 2) the handicap basis, and 3) the percent of
the difference between their average and the handicap basis that is
used for the handicap.
For example, a typical league may calculate handicap as 80% of
200, meaning that a bowler with a 150 average would have a 40-pin
handicap (80% of the 50-pin difference between their 150 average
and the 200 basis). With a 40-pin handicap, the highest handicap
game this bowler could roll would be 340.
Theoretically, you could have a 600 handicap game: A bowler with
a 0 average bowling in a league with handicap based on 100% of 300
would get 300 pins of handicap, making a perfect game worth 600
pins. In reality, I don't think I've seen many handicap games over
330.
