In typical league bowling, a series is three games. Bowling an 800 series is considered to be an achievement about four times more difficult than bowling a 300 (perfect) game. Every time a bowler earns an 800 series in league bowling, the score is reviewed and then sanctioned by the United States Bowling Congress, and then entered into that bowler's permanent file.
