MaMills is a three-dimensional take on four-in-a-row played on a 4×4×4 grid where gravity stacks your dropped cylinders naturally. With 76 possible winning lines including diagonals through the cube's depth, it demands spatial thinking beyond traditional flat board games. Solo players can challenge five AI difficulties, while local and online multiplayer options make it accessible for competitive friends.
