We had a great bowling party for our son.  The first two games were regular with prizes for the low and high games.  The best was when we had the crazy bowling portion of the party.  I had a list of criteria on a sheet of paper for each frame of the game. Some of them were as follows: Bowl between the birthday boy's legs (hysterical) Bowl with your eyes closed Bowl with your other hand Use someone elses ball Twirl around three times and bowl.  These are just some that I used.  The best part of bowling in this manner is that age doesn't matter or if you win or lose. It's just crazy, fun and the kids loved it.
