I don't think they track it, but I've seen a sanctioned 7 game!
lowest score wins bowling
The lowest score possible in bowling is zero.
In tournaments, at the end of the round it is added to the final sanctioned score.
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.
150 would be the lowest possible score. XX-XX-XXXX--
They don't track low scores but I've seen a sanctioned 50 for 3 games.
Open bowling 120, league bowling 140.
A negative eight in bowling is impossible. The lowest score one can have for a game is 0.
