About Opus Magnum

About this game

“It is not an exaggeration to say that without alchemical engineering, civilization would not exist.”

Hailed as the most promising alchemist of his generation, Anataeus Vaya has just accepted a position as Head Alchemist of House Van Tassen, the oldest and richest of the city’s ancient Houses. But dangers lurk behind the family’s opulent facade, and alchemy alone may not solve every problem.

Opus Magnum is the latest open-ended puzzle game from Zachtronics, the creators of SpaceChem, Infinifactory, TIS-100, and SHENZHEN I/O. Master the intricate, physical machinery of the transmutation engine— the alchemical engineer’s most advanced tool— and use it to create vital remedies, precious gemstones, deadly weapons, and more.

Design Machines - Design and build machines that carry out alchemical processes using a variety of components including programmable arms, customizable tracks, and more esoteric devices like Van Berlo’s wheel and the Glyph of Animismus.

Open-Ended Puzzles - Compete against your friends and the world to build the simplest, fastest, and most compact solutions to the game’s challenges. Export animated GIFs of your elegant designs to show them off.

Steam Workshop - Make and share your own puzzles with full Steam Workshop integration and an easy-to-use puzzle editor. Play the top user-submitted puzzles in the prestigious Journal of Alchemical Engineering, curated by Zachtronics!

Rich Story - Intrigues and dark plots swirl around the city’s ancient Houses. Alchemists, who hold the power to create almost anything known to science, are highly sought— and highly dangerous.

Solitaire Minigame - Alchemical engineering takes focus and concentration. Take a break with Sigmar’s Garden, an original alchemy-based solitaire game. Every game is winnable, but not every game will be won…

This is a logic puzzle game. On a board consisting of hexagons, your goal is to transform input 'molecules' of given colors into specified outputs. You achieve this putting machines on the board. Simple ones change an atom's color, when the atom is hovered over it; cranes can be used to grab, move and rotate molecules, but you need to program their actions. I love how simple problems and simple solving mechanisms are turned into logic riddles. The difficulty raises slowly. It is rather difficult to get started, since there are many different actions already given at the start. I guess this is a burden for many players. However, once I got into it, it hooked me. For those, who do not only want to build 'a' solution, but want the 'best' one, there are three criteria to be optimized: time needed for the machine to build the output, space needed by the machine, and money needed to build the machine. After completing a match, the values of the best solutions of your friends are shown, and a statistical chart generated by all users that finished the level is also given for each of the three criteria. So at start, this is a competition the game vs you - afterwards, (and if you like) it is a competition of the best other players and you. There are some drawbacks, though. In the endgame, as always with these kind of games, the problems become very complicated and it takes hours to solve them, which can be tedious. Further, the interface is sometimes unintuitive. I needed to google how to scroll through the programming code, when my screen was too small to show it all the the same time.
