We need to navigate from the top left corner to the bottom right corner, by picking "the path of least resistance". The colour of the arrows, along with the title, is supposed to remind the participant of resistors and their colour codes. The solution then is just the path which results in the overall lowest combined resistance. Solution ('d' for down and 'r' for right) : drddrrddrrddrdrr.
