AI tools were used to help build MaMills: much of the code, the visual and interface design were created with AI assistance, then reviewed, tested and refined by the developer.
Nothing is generated while you play. The Machine, your computer opponent, is classic board-game logic that looks a few moves ahead.
Not a generative AI, and the game sends no data to any AI service.
The cylinder drop sounds were made by the developer, and the music is "Deliberate Thought" by Kevin MacLeod.
