Instead of walking up the hill to your right, you will go left instead. Hole #20 will now shoot down the next ski slope all the way to the bottom. Hole #21 will then play from the bottom of the hill up to where #20’s basket is now. The course then continues back to normal. Hole #21 is now #22, hole #22 is now #23, and hole #23 is now #24. I’ve added a picture to illustrate the changes.
