It's called Freeze Time - Standard adjustment #38

Gimli vuk - loosen the return ramp and slightly shift its positioning. This one will require a lot of trial and error but eventually you should find the sweet spot. Had to do this on mine and now it's about a 1% failure rate. Same thing goes for airballs off the Legolas ramp; shifting the ramp position has a huge effect on how that shot behaves.

Baradur bounce outs - I removed the small spacer that's screwed into the playfield behind the saucer and placed drop dead foam on the scoop. Near 100% retention rate now.

Cave troll is pretty easy to beat with the standard 3 balls, so I always try to leave the add a ball for later, and IMO 2 ball DTR is the only way to go! Such a satisfying shot when you hit it.

This thread is about TSPP but they are both Whitestar so it should still apply.

Last night I was 4 shots away from Valinor (Gandolf, Merry, and the two ring shots left) on ball 2 but drained. I plunged ball 3 and unbelievably was able to re-qualify all three multiballs and start a second DTR to Valinor attempt. Got 4 shots away and drained again.

Thank God there wasn't a real sword on top of my machine.

+1 to everything LOTR_breath mentioned. The first time I got two balls stuck on the magnet I waited for the ball search to clear it - don't do that. A few minutes later I was waiting for the soldering iron to heat so I could replace that transistor!

I had the same problem with bounce outs and a few other things could be causing it. Check that the spinner at the ramp entrance is hanging at 90 degrees to the playfield, which means the top edge is slightly tilted towards the player. It tends to mushroom over time and hang with the bottom edge towards the player, which can rob the ball of momentum as it enters. Carefully bending the wire arms will change the angle at which it hangs.

The tips of the ring ramp will also mushroom from rejected ring shots, and can affect the ball if it gets too bad. File those down flat.

You can also slightly adjust the aim of the ramp by loosening the mounting screws and twisting the ramp, then cranking the nuts down tightly.

The bolts are welded to the ramp so nothing to hold topside. Typical thru-holes secured with washer and nut, so you won't have much wiggle room, but that small adjustment might help and it will take 30 seconds to do. Start with the spinner first as that will have a major impact on the ball if not hanging correctly. And of course rebuild the flippers if you haven't already.

Keep working on it until you can make that shot cleanly, and DON'T change to single ball. 2-ball DTR is where it's at on this game and you'll be missing out on the stress of having to make that clean shot under pressure!

Remove the small post and screw, then put drop dead foam or some weather stripping on the metal catch. No more bounce outs!
