PolyformSolver is a free Windows application for creating and solving geometric polyform puzzles.

Choose from a wide range of 2D and 3D grids. Puzzle-piece sets can be created manually or generated automatically, target shapes can be drawn, and matching solutions can be calculated. Example puzzles make it easy to get started.

Three-dimensional puzzles can be explored in interactive 3D views. Solutions can be displayed simultaneously in 2D and 3D. An animated assembly sequence shows step by step how the pieces can be added from the bottom up.

The interface can be switched between English and German. PolyformSolver is ideal for developing geometric puzzle ideas, testing puzzle shapes, and checking whether a set of pieces can completely fill a selected target shape.

IMPORTANT: For a correct installation, please read the Instructions before unpacking!
