Opus Magnum is an alchemy based puzzle game. After being appointed head Alchemist at an ancient university, the player must complete various transmutation problems to unearth a hidden plot.

Science creates

Based around a grid and mechanical arms, Opus Magnum tasks players with transmuting various elements into a variety of other conceptions. Puzzles consist of a simple objective and an open-ended multitude of options for completion. While initially confusing, this gameplay mechanic quickly becomes familiar. Each puzzle can be completed in a faster or more efficient manner once the basics are grasped with high scores compared globally. The steampunk aesthetic works well for the subject matter and, despite being a fairly weak background plot to the puzzles, adds a nice additional element to the overall game. Opus Magnum also features a solitaire-esque mini game and Steam workshop creation tools for custom puzzles. A lack of time constraints or objectives makes for a relaxing yet engaging puzzle game which should be an instant classic for fans of the genre.
