I've been searching every where for a website that has about 500 pinball rules sheets, and it seems to not exist.
Let me state were I've been: IPDB does NOT include game instructions, KLOV, PINSIDE, Daveland ( World Pinball Directory-all web links too), IFPA. etc,.
Sites that have some game rules and strategy of play:
Pinball.org (PAPA), pinball news.com, stern pinball.com, gameplanpinball.com, (and now Tiltforums, pintips, VPForums) have some more, BUT these sites combined will only account for about 250. PLUS the rules are only in type set, which makes it hard to understand the instructions because there are NO pics.
If there isn't one, then let's make one place that you can find several hundred pinball games rules and strategy, and especially with screen shots of the play fields. It would be a highly visited website! NOTE: let the game owners put up the info, so the site owner won't be doing much of the work.
