There's always that one hole where you have to hit the ball hard enough so it goes around the vertical loop ramp but not too hard so that it then bounces at the right angle to get anywhere near the area of the hole that's blocked by a whole bunch of strategically placed pieces of wood.
Most of the times I played it, my group is enjoying themselves on holes 1-5, is getting tired of being held up by the group in front of us for holes 6-12, and is getting noticeably bored by hole 13, but feel like we have to finish it. It's a game that starts fun and becomes obligation.
