group play should say "pay attention to which player's up" because extra balls interrupt the players alternate after each drain (as does ball save).

"Same Game, Different Rules - Each pinball machine plays differently, but adhere to the same general rules" - do they have different rules or same rules? lock 3 balls for multiball?

"Flashing Lights" plenty of pinball machines indicate valuable targets with solid lights. There's also the issue of players not recognizing that, for example, an lit arrow insert pointing to the orbit means to shoot the orbit - the arrow is along the playfield after all.

anyways, that poster has way too much information on it.
