The golfer takes three balls and throws them above their head in the rough near the green. The golfer must play the three balls as they lie to three different holes on a putting green. The golfer can decide which ball they want to play to each hole and then must try to get each ball up and down to the three locations.
3 up and downs = 1 cycle
Count the number of cycles and up and downs made. If a golfer goes through two full cycles and only gets one up and down the next time, the total score is 2.1.
