Route the outer pairs around the edges of the screen.
Why It Works
Three matching pairs share the middle of the board, so joining them with straight lines is impossible without overlaps. The blue pair goes straight through the center, while the red and yellow pairs swing around the outside. Routing around the edges avoids every crossing.
