Quoted from Joe_Blasi:Stuck balls? (they did not list any thing about that there rules are for that?)
I'd suggest that any game with a stuck ball is not eligible to be in this competition.
As a more general observation, I like the idea of involving people in on-line forums as a way of brainstorming all the contingencies that need to be addressed. This notion of continuous "hardening" of the design with input via on-line discussion is what made IPDB the great community-built resource it is, and it helps a lot for show administration and many other aspects of pinball.
