Stroke Play is form of competition and scoring system in which the total strokes taken during the round (or rounds) are added together to give a cumulative score. In stroke play, every side (player or team) competes all holes² and counts the total number of strokes and the side with the lower total score wins.
The final stroke play score is expressed in a total number of strokes (e.g. 69, 74) or alternatively as the difference between a total number of strokes and the course par (e.g. -3, +2). A negative result means that the achieved score is lower (better) than the par.
Beside the number of strokes, the stroke play round may be scored in a few other official formats:
