NOTE :
These tips are meant to to be used only if you're truly frustrated with the puzzle. If not, start with the 'learn' mode and work your way up. Chances are, you'll figure out all the tips below yourself and it'll be a lot more rewarding that way.START AT THE EDGES
This tip does not apply if you have wrap turned on. Without wrapping, you know that power can't flow off the edge. This means that no line should be going towards an edge. So for straight tiles, they should run parallel to the dge they are next to. For 3-way tiles, the empty side of the tile should be the one next to the edge.

BE EFFICIENT
In almost all cases, there is only one path leading to a particular tile or area. If you see two lines with power heading to the same tile or section, one of them should be diverted somewhere else.

BAD
DEAL WITH "STRAIGHT" TILES FIRST
If a straight tile is connecting on terminating tile to another, then you know it has to be in the other direction as it cannot get power to itself in this configuration.
GOOD
BAD
FORM CLUSTERS
Even if you don't have power reaching a section of the puzzle, try to get all the pieces in that region connected to each other to form one coherent network. Once you have a few of these connected sections worked out, you can then figure out hose to get power to each of these clusters.
