Jigsaw Design Tool

The tool abstracts the puzzle design problem into a grid-based generator. Given an input image or a target physical size, it computes usable grid dimensions, estimates the number of pieces, and proposes an interlock-ready layout suitable for fabrication.
A core algorithm creates a tile grid, assigns interlocking edge shapes, and clusters colors to support visualization or color matching. Users can choose rectangle or irregular grids, adjust piece_size_mm or target_pieces, and set a difficulty level to influence tab density and curvature.
Outputs include an SVG layout with piece outlines and a metadata bundle describing coordinates, grid geometry, and color regions. The tool supports deterministic results when a seed is supplied, enabling reproducible projects across teams or classrooms.
Unique value lies in its manufacturing focus and export readiness: it provides ready-to-fabrication geometry, batch generation capability, and formats suitable for laser cutting, printers, and educational worksheets.
