> Hi all,
> I'm having trouble with the circuits job, I have already solved the booster's one. I think I have the lay out figured out (all facing same way and inner-outer interchanged, but everytime I go out and back in one more circuit breaks down, I now have 4 broken down, and can't connect two because one is broken to the north and the one to the north is broken to the south. Does that make sence? How do I get around that? Please help!!

The conduits don't break down any more than how they start. In fact there are just two broken conduit segments. It's like a diagram where you have straight lines connecting dots. The breaks happen in the middle of the lines, and the dots are the places you visit. So whenever there's a break, you can *see* it from the dots on either end. It's the same sort of thing with the power conduits, except because the station isn't flat, the lines have to curve along the surface.

So, like you said, there's a spot where on the north side you see it broken to the south, and on the south side you see it broken to the north. You *can't* connect those two junctions. However you turn the junctions, one of the links will point either north or south, so a broken conduit to the south means you want one of the links where you are to point north (otherwise the circuit hits the broken part and stops).

In fact you can't afford to waste any of the links, so not only do you have to avoid pointing any of them at broken segments, but whenever a link points to an adjacent junction, one of the links at the adjacent junction *must* point back at the first one. So if one of your links points across the outer parallel, then if you move along the direction of that link, at the place you come to you have to point a link across the outer parallel as well.

In the case of links pointing north/south, it's easier: if you point north from somewhere, then move north to a new junction, you have to have a link point back to the south from there.

This is the most important rule for the puzzle. Also remember that the circuit has to go through *all* 12 of the junctions before coming back to where you start, and as you move along the circuit from junction to junction, you can't cross the inner parallel twice in a row and you can't cross the outer parallel twice in a row.

If you have a well drawn diagram or if you visualize it carefully, in fact you will see a nice pattern come out of it as you move from junction to junction, orienting each one's links so that you continue to follow the rules (and keep from going back to a junction you've already visited).

The only problem left is knowing how to start with the *first* junction's links. That might take guesswork or a bit of forward thinking, but even if you solve the problem by guessing you can cut down the risk of getting stuck by starting next to one of the broken segments. Then, for example, if it says the segment to the north is broken, you know the links have to be (south/inner) or (south/outer) there. Instead of a 1 in 4 chance of guessing right, you have a 1 in 2 chance, and if you don't get it right the first time, you will the second time.
