Printable Maze Puzzle — Seaborn

A rectangular maze puzzle visualization with clearly marked start and goal positions. The maze is algorithmically generated to guarantee exactly one solution path from start to finish. The clean black-and-white design is optimized for printing, allowing users to solve the puzzle with a pen or pencil.
