Mandatory
A mandatory (or "mando") is a marked object, like a tree or pole - that your disc must pass on a specific side, as shown by arrows on each individual tee hole sign.
Out of bounds (OB)
If your entire disc is visible in the area marked on the course signs as OB, your disc is out of bounds. You must take your next throw from 1 metre inside the course from where your disc crossed out of bounds. Additionally, going out of bounds incurs a one-throw penalty, which is added to your score for that hole.
Permanent water hazards, public roads and walking paths are always out of bounds. Do not enter the water to retrieve lost discs, safety comes first!
Lie
A lie is the spot where your disc comes to rest after a throw. Take your next throw from directly behind the discs resting place.
Tee throws
Each hole begins with a tee throw. Tee throws must be completed within or behind the designated tee area.
Throwing order
The player with the least number of strokes from the previous hole is the first to tee off on the next hole. After teeing off, the player whose disc is furthest from the basket always throws first.
Fairway throws
A fairway throw is any throw made after the first (tee) throw. Fairway throws must be made from directly behind your lie. If your disc is more than 10 metres from the basket, you can do a normal run-up and follow-through. But if your disc is within 10 metres, you must stay behind your lie and not step past it until the disc is at rest.
Completion of hole
A disc that comes to rest in the basket or chain constitutes successful completion of that hole.
