Opus Magnum is the latest open-ended puzzle game from Zachtronics, the creators of SpaceChem, Infinifactory, and SHENZHEN I/O. Design and build machines that assemble potions, poisons, and more using the alchemical engineer’s most advanced tool: the transmutation engine!
Each input wears a grade, S to D, read from the buyer's side. The color is the direction: green raises the score, red lowers it, grey sits neutral. ▼ marks a dock, ? a missing input, • a fact this genre's score does not use. The exact weights stay secret. These are the inputs and the direction each pushes.
Most players never reach the end. On a 15.4-hour game, that's a lot you pay for and may never use. Steam global achievements
