Section 3: Playing Area
- 2.1: A minigolf course has 18 clearly marked, numbered lanes that must follow the standard rules of their system.
- 2.2: A tournament-approved lane contains the playing area, the boundary (usually barriers), the marked teeing-off area, optional obstacles, an optional border line (red paint), optional helping lines (dotted black paint), optional repositioning markings (optional on MOS, black paint), the target (hole or other lane-specific target) and further system-specific markings.
- 2.3: The measures of the playing area are defined in the system-specific rules.
- 2.4–2.5: Boundaries must be clearly visible and, where not a barrier, marked in some other way. Every lane must have a marked teeing-off area, standardized across a course or system.
- 2.6: Obstacles must be functional and fixed. Moveable parts over or through which the ball is supposed to pass are not allowed; unfixed obstacles must be marked as such. Each obstacle must differ from the others on the course and its effects must be calculable.
- 2.7: The border line marks how far the ball must travel from the teeing-off area to remain in play. If the first obstacle takes up the whole width, the end of that obstacle is the border line. The line is correctly passed when the ball has passed it with its point of contact.
- 2.8: The helping line marks the end of any obstacle after the border line and defines the direction in which a ball may be repositioned.
- 2.9: Distance measurements for markings include the markings themselves.
- 2.11: If the target is a hole, its diameter must not exceed 120 mm (4.7 in).
- 2.14: A course is eligible for international and national tournaments only if approved by the WMF.
- 2.15: No changes may be made to the lanes (e.g. drilling holes). Players and coaches must not mark the lanes with writing implements, putters or other objects. Small paper or plastic rings may be attached in the tee-off area, and removed if the player feels they disturb play; in repositioning areas they may be used only temporarily to stop the ball rolling away.
- 2.16: The head referee decides whether a lane is playable. If more than 6 of the 18 lanes are unplayable, the course is considered not playable. In special cases fewer than 12 different lanes can be used for a 12-lane round (some played twice) if the schedule and format allow.
