Author/Opus: This is the 224th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Fully shade some outlined regions in bold to create a maze with paths made out of the unshaded regions. The direct path of the maze from the start (S) to the goal (G) must pass through all of the circles but none of the triangles. All regions containing S, G, circles, and triangles must be unshaded and part of the maze. No 2×2 area can be fully shaded or fully unshaded. All unshaded regions must be connected by edges, but there can be no loops anywhere in the maze.

Difficulty: 2.5 stars

Time Standards (highlight to view): Grandmaster = 2:00, Master = 3:15, Expert = 6:30
