Quoted from tamoore:There are some other ridiculous ones such as on rocky and bullwinkle, where you have so little time to complete one, that the chance you're going to is very small. The "Waybac" mode on R&B gives you only a few seconds to hit a ramp as many times as you can, with the ball returning to the wrong flipper. If you get one, you're doing well.
That's not exactly the case. The ball returns to the left flipper, meaning you're supposed to back-hand the shot as they intended. It only takes 2 seconds to loop the shot, and they give you 4 seconds in order to make it (after the first grace period). That's plenty of time. I hit 11 in a row once, and time was never an issue. It's designed to run out of time if you miss the shot, so the point of the mode is most consecutive back-hand shots without a miss. That's why the game saves a separate high score table for this mode alone.
BTW, if you can't back-hand the WABAC ramp, then something is seriously wrong with your machine. It's the easiest shot in the game.
