Trace the Circuit - Part 3 - Solution
by
Erik Oosterwal
If you have not had a chance to try out Trace the
Circuit and Trace the Circuit - Part 2
on The Puzzle Page, I suggest you try those before
attempting this one. In the earlier trace the circuit puzzles, you
only need to connect 2 nodes on each circuit instead of 3.
As with the other circuit tracing problems, and similarly to the
Walking Through the Mall puzzle, the key to finding
a solution is to find the circuit that cuts the grid into two parts. In
this puzzle, the circuit with the nodes labled 'A' is the one which does
this. Once you figure out which circuit is the key circui you then
need to figure out on which side of the 'A' circuit the other circuits lie.
You can see in the solutoin below how to connect the nodes so that
no circuit touches or crosses any other circuit.
