Decide on a scoring system. We like two points for a bogey, five for a par, 10 for a birdie and, hell, 50 for an eagle. Make that score on a hole and those points are yours… unless you elect to roll them over. If you do, and you score on the next hole, then the points from the previous hole are doubled. However, if you make double bogey or worse, not only do you lose the points but a further five as well.
