Course #723 has nine holes and a par of 21. It is built from its number, so it is the same course for everyone who plays it. 6 holes are par 2 and 3 par 3.
The longest is hole 6, which runs through 4 rooms. Water crosses hole 9; the bridge is the only dry way over, and a splash costs a stroke.
Slopes on hole 1 pull the ball sideways or back — aim to the high side. On holes 3, 4, 5, 6 and 7 a bank cut across the corner turns the ball through a right angle. A bowl around the cup on holes 5, 8 and 9 draws gentle putts in.
A gentle course: most holes are par 2, so a round at par is within reach once your pace is right.
