MaMills press kit
Last updated: September 29, 2026
MaMills is four-in-a-row, but the board goes up too. It is a cozy 3D board game for Steam Deck, Windows, macOS and Linux: drop cylinders onto a 4x4 grid of sixteen sticks, let gravity stack them, and line up four along any of 76 lines, through rows, columns, stacks and diagonals through the cube. Play the Machine at five levels, from Beginner to Expert, or a friend three ways: on one device, over your local network, or with Steam Remote Play Together. Forty puzzles, each with exactly one right first move. Four palettes, patterns so nobody needs the colour, and a first seasonal theme, Halloween. No streaks, no daily chores, nothing to buy inside.

What sets it apart
- 76 ways to win on a 4x4x4 board, and gravity decides where every piece lands.
- The Machine plays at five levels, Beginner to Expert. Expert thinks four moves ahead.
- A friend three ways: Hotseat on one device, LAN with no Steam needed, or Steam Remote Play Together, where they need Steam but not the game.
- Puzzles: forty of them in five levels, eight in each, every one with exactly one right first move. Win in one, stop a threat, or on Hard and Expert find the one move that wins on your next turn, whatever the other side does.
- Built for Steam Deck and tested on it from the first day, and on Windows, macOS and Linux too.
- Never colour alone: a colour-blind safe palette and patterned pieces, text size, reduced motion.
- Our first theme, Halloween: spiders against pumpkins under the moon, in the game from release day, with more seasonal themes to come.
