Game update28 Jul 2026UPDATE: In-game option for setting the GIF output directoryToday's update adds an in-game option for setting the GIF output directory. Clicking the "SET" button should open an OS-level folder picker dialog, which seems like exactly the kind of thing that won't work for many people, especially if you're on a more esoteric operating system. If you run into any trouble, email me at [email protected] and we can investigate!
Today's update actually contains a Korean translation of the De Re Metallica DLC, unlike last week's update that only translated the puzzle names and the Journal of Alchemical Engineering. Thanks again to Haxton from the unofficial Zachtronics Discord for this contribution.

Today's update adds the final issue of the Journal of Alchemical Engineering, at least for now. It also adds a new achievement, The Way of the Philosopher , for players who solve at least one puzzle in each of the 24 journal issues. Thank you to everyone who submitted a puzzle in the last few months (over 750 submissions!) and even more thanks to the super-players who sorted through these (did…
Today's update adds a new issue to the Journal of Alchemical Engineering. Volume CVIII, Issue XI: Small-Scale Construction Crafts While research to support the large-scale building projects initiated by the Great Houses has shown a tendency to dominate today’s alchemical science, a dedicated cadre of independent practitioners has managed to initiate a revival of interest in older, half-forgotte…

Opus Magnum jest teraz dostępne po polsku! Opus Magnum is now available in Polish! Thanks to Michał "Doczek" Dokrzewski for providing a Polish fan-translation, which also includes the DLC and is now available in-game! This update also includes a fix for ExternalLeaderboardURLs not properly uploading GIFs, whatever that means. It's kind of an IYKYK situation.
Today's update fixes the crash with Intel integrated GPUs by upgrading the game from a 32-bit to a 64-bit binary. This is good news for anyone with an Intel integrated GPU, as you should no longer need to force OpenGL usage on Windows, but bad news for anyone still running a 32-bit version of Windows. (Although, if this does apply to you, you should still be able to switch to the "previous" bra…

Today's update fixes a bug where the cursor was misaligned in fullscreen mode on notched MacBooks, although the issue seems to persist when the game is running in a window. I'm still looking into that part. This update also fixes a bug where pivoting the same atom in two different directions with two different grabbers was somehow not considered an error. I'm shocked we didn't fix this sooner!
