Abandoning simple and repetitive basic layouts, the advanced stage features super complex grid structures, dense marker pairs, and tricky route obstacles that challenge your top-level problem-solving abilities.
Every advanced level requires precise and rigorous path planning. You must use straight or right angled paths to connect all marker pairs, achieving complete mesh coverage and completely avoiding intersections and overlaps. The 60 second time limit creates a compact solution window that requires fast analysis and efficient layout design. Every incorrect action will result in level failure and energy consumption, leaving no room for random attempts.
