Polyform Puzzler



Polyforms are sets of all possible shapes constructed from multiple basic units (squares, triangles, etc.) following some simple rules. These shapes can then be combined into larger shapes, often in many different ways. These are polyform puzzles. (More info in the FAQ.)

Polyform Puzzler is a set of solvers for many polyform puzzles (like Pentominoes and Soma Cubes), and a software toolkit for exploring & solving polyform puzzles. It consists of a set of front-end applications for specific polyform puzzles and a Python library that does the heavy lifting. New polyforms and new puzzles can easily be defined and added. Python 2.5 or higher is required, but the latest 2.x.y is recommended.

A Sudoku puzzle solver is also included. The same back-end puzzle solving engine is used to solve Sudoku puzzles and polyform puzzles.

Here are some examples of polyform puzzles (all solved & drawn by Polyform Puzzler!):


Polyominoes, Pentominoes, & Hexominoes: 6×10 Pentominoes Rectangle (also, An Introduction to Polyominoes)


Polyhexes & Pentahexes: 10×11 Pentahex Parallelogram (also, An Introduction to Polyhexes)


Polycubes & Solid Pentominoes & Pentacubes: Pentacubes 5×9×9 Fortress (also, An Introduction to Polycubes)


Polysticks: 3×7 Diamond Lattice (also, An Introduction to Polysticks)


Polytrigs (triangular-grid polysticks): Tritrigs 3x1 Semi-Regular Hexagon Ring (also, An Introduction to Polytrigs)

All the details are in the FAQ and the Puzzles & Solutions doc.

Polyform Puzzler also solves Sudoku puzzles!

The Puzzles & Solutions document lists all implemented puzzles and solution counts where known. We include a directory containing solutions to the puzzles Polyform Puzzler solves. These solutions are also available as a Gzip-compressed tarball.


In addition to the main Polyform Puzzler code, in the "misc" repository there is some maze-generating code.
