Rule 24 covers team competitions (played in either match play or stroke play), where multiple players or sides compete as a team with the results of their rounds or matches combined to produce an overall team score. 

Rule 23 covers Four-Ball (played either in match play or stroke play), where partners compete as a side with each playing a separate ball. The side's score for a hole is the lower score of the partners on that hole. 

Rule 22 covers Foursomes, where two partners compete together as a side by alternating in making strokes at a single ball. The Rules for this form of play are essentially the same as for individual play, except for requiring the partners to alternate in teeing off to start a hole and to play out each hole with alternate shots. 

Rule 21 covers four other forms of individual play, including three forms of stroke play where scoring is different than in regular stroke play: Stableford, Maximum Score, and Par/Bogey. 

Rule 20 covers what players should do when they have questions about the Rules during a round, including the procedures (which differ in match play and stroke play) allowing a player to protect the right to get a ruling at a later time. Rule 20 also covers the role of referees who are authorized to decide questions of fact and apply the Rules. 

Rule 19 covers the player's several relief options for an unplayable ball. This allows the player to choose which option to use - normally with one penalty stroke - to get out of a difficult situation anywhere on the course (except in a penalty area).

Rule 18 covers taking relief under penalty of stroke and distance. When a ball is lost outside a penalty area or comes to rest out of bounds the player must resume by playing again from where the previous stroke was made. This Rule also covers how and when a provisional ball may be played. 

Rule 17 is a specific Rule for penalty areas, which are bodies of water or other areas defined by the Committee where a ball is often lost or unable to be played. For one penalty stroke, players may use specific relief options to play a ball from outside the penalty area. 

Rule 16 covers when and how the player may take free relief by playing a ball from a different place, such as when there is interference by an abnormal course condition or a dangerous animal condition. 

Rule 15 covers when and how the player may take free relief from loose impediments and movable obstructions.
