The Harem Rape/Exploit lets you basically score until you're bored.

From the link:

"start the rocs mode last. this means no collecting 2 jewels with the ruby because that gives you your mode + rocs. then shoot the left orbit when M is lit, you'll hear the audio for starting harem but it won't actually begin because rocs is still running. shoot the ramp to collect the rocs jewel and then shoot the genie. killing the last skeleton by shooting an orbit grabs the ball with the same magnet as harem does, this starts harem and genie battle at the same time. keep shooting it into the bumpers and take care to shoot the other shots when necessary, staying alive but not beating the genie."

And alternatively:

"Actually what got it removed was a similar tactic, but not taking advantage of the bug you described. Shooting the bumpers scores a HAREM letter, then catch the ball... wait for tiger saw, uh, tiger loop to expire... shoot the bumpers for another HAREM letter. Fifth letter starts the multiball.

Then, during Harem Multiball, keep shooting the bumpers. During the multiball, and only then, bumpers add 5000 to the jackpot value instead of 1000, and you're scoring that jackpot every time you hit anything... anything including each bumper.

This wouldn't be so bad, but the jackpot value carries over during the same ball -- so you can then start Harem Multiball again with a base value of 400k instead of 50k. Big, big score in a hurry.

I got the Harem value up around 1.2 million -- for every switch hit. Takes a long time, really boring, basically not good skill pinball. Top qualifying scores were 368M and 285M... and yes, I'm very glad to be rid of that game at PAPA A."
