An autosolver for Opus Magnum puzzles. It generates correct but very inefficient solutions.

This version is a command-line program which generates .solution files from .puzzle files. If you're looking for the original version which works on the actual game screen, see https://github.com/gtw123/OpusSolver/tree/v1.0

• All puzzles in the main campaign
• All journal puzzles (except production puzzles)
• Most puzzles created in the standard editor

• Production puzzles
• Puzzles which have molecules that can't be reduced to single atoms (e.g. if the Glyph of Unbonding isn’t allowed).
• Puzzles using features not in the standard editor, like triplex bonds between non-fire atoms, partial triplex bonds, or disconnected atoms.

• Install Visual Studio 2022.
• Ensure you have NET Framework 4.8 Development Tools intalled.
• Open OpusSolver.sln in Visual Studio.
• Build!

Currently tested on Windows only.

• To generate a solution for a puzzle, simply run OpusSolver.exe <path to the .puzzle file>. This will create a corresponding .solution file in the current directory.
• You can also give it multiple files or directories to run on.
• For other options, run OpusSolver.exe with no arguments.

Puzzles created in the game are located at C:\Users\<username>\Documents\My Games\Opus Magnum\<steam ID>\custom

Puzzles downloaded from the Steam workshop are at C:\Users\<username>\Documents\My Games\Opus Magnum\<steam ID>\workshop

For other examples, including .puzzle files for the built-in puzzles, see omsim.

• Copy the .solution file directly into C:\Users\<username>\Documents\My Games\Opus Magnum\<steam ID> then restart Opus Magnum.
• Go to the corresponding puzzle within the game.
• The generated solution will be called Generated solution.
