I am sure someone can be more specific - but I have been watching season one on Netflix recently and a lot of the cues come from early episodes (Mr. Death (guy on the backglass and middle of the playfield), The hitchiker, the slot machine, the swirl (if that comes from the episode where the guy's dream kills him - he is at the fair and playing a game where he is trying to shoot the center of the swirl).
I am sure there is more than I am missing .. but if you watch the first 15 episodes or so, a lot of the game will start to make sense.
