The default for QMB is 2, and I’m fairly sure it’s just ramp QMBs. It is at least in the realm of possibility that cellar QMBs count against you (since after you play QMB from cellar, the drop will time out all the way down after the next ramp shot (or start the next ball totally off)).
Extra balls dry up in the game, so you’re limited how many cellars you can do. I have NEVER seen QMB disabled like extra ball is.
Personally I recommend setting QMB limit to 99, because the compass does have an unsettable limit of 10. The game’s really a bummer with no compass, no QMB, and no cellar.
Whirlwind can serve to total ripoff in multi player games. With two balls in the lock trough as kindly provided by your opponent, you can start both multi balls as a stack with your very first shot of the ball (celler when lit for Quick MB). Or else four ramps and the drop.
Love the multiball stack on that game, it can be so huge. If no one else has said this, the stack is even better because of the longer display effect. If you park a ball in the cellar you have enough time to gather and shoot with the second ball. Get another jackpot and the whole effect happens again.
Because of this, Whirlwind is the only game where my personal best is better than the #1 score on Pinball Arcade.
