About This Game

MaMills is a 4×4×4 spatial tic-tac-toe with gravity-stacked drops - vertical sticks, four-in-a-row in any direction wins.

This game is a tribute to my late Grandmother (aka Mami), who I used to play this game with. I loved it then, and I love it now; I hope you find some joy in it too! ❤️
This is a cozy puzzle game that I hope you enjoy as much as I do.

Four-in-a-row, but the board goes up too

MaMills is a calm, controller-first board game. You drop coloured cylinders onto a 4×4 grid of vertical sticks, gravity stacks them, and the first player to line up four wins. Because the pieces stack, every stick is also a column, every row of sticks is also a plane, and a line can run corner to corner straight through the cube. Sixteen sticks, sixty-four places, seventy-six ways to win.

I learned it from my grandmother, Mami. It is an old rule set that people have played for generations. This is that game, made digital, with a clear layout to be comfortable to play.

How a match goes

• Pick a stick, drop a cylinder. A beam and a ghost piece show exactly where it will land. Four pieces fill a stick.

• Four in a row wins. Rows, columns, vertical stacks, plane diagonals and the four cube diagonals all count, on every level. 76 lines in total.

• Rotate the board, or lock the angle. Orbit freely to read a position from any side, or freeze the camera and play from the view you like.

• Hint shows every live threat. One press rims the opponent's three-in-a-rows and marks the stick that blocks each one. Block it, or race it.

• Undo, pause, walk away. Take the last move back, pause any time, and a match you leave is waiting on the main menu when you come back.

Four ways to play

• The Machine – five levels from Beginner to Expert. Beginner leaves room to learn; Expert does not.

• Hotseat – two players on one device. Type your names, then pass the controller or the Steam Deck back and forth.

• LAN – two devices on the same network, each with its own screen. One hosts, the other joins; no Steam account required for either.

• Remote Play Together – invite a Steam friend and play over the internet. They do not need to own the game.

Learn it in a few minutes

A short story-driven tutorial teaches the rules inside a real board, one control at a time, and ends on a card of the four winning shapes. A six-puzzle ladder follows: one-move positions that train you to see wins and blocks across rows, stacks and diagonals.

Make it yours

• Four palettes – Classic red and blue, Violet, a colour-blind-safe blue and orange, and Gold & Silver, which unlocks when you beat Expert.

• Eight drop sounds – pick the one you like, from a soft bop to glass and cherry. A background track you can turn down or off.

• Two loading screens – a tumbling cube of cylinders, or the windmill with cylinder sails.

• Your controls – full keyboard and gamepad rebinding. Every action shows its button on screen, and the glyphs follow whatever you are holding.

Accessibility

• Patterned cylinders – stripes on one side, dots on the other, so colour is never the only cue.

• Text size from 85% to 130%, applied to every label and button.

• Reduce motion, opaque backgrounds behind every dialog, mono audio, adjustable drop speed, and an optional X, Y, Z readout of the highlighted stick.

• English and Hungarian interface. There is no speech, so nothing to dub.

Built for Steam Deck

Designed and tested on the Deck from the first day: controller-first, readable at the Deck's native resolution, and safe to suspend mid-match. It plays just as well on the desktop with a keyboard and mouse or any gamepad.

On Steam

• 21 achievements – 15 you can see coming and 6 hidden ones for the sneaky lines.

• Lifetime statistics and three leaderboards: longest win streak, total wins against the Machine, and fewest placements to beat Expert.

• Steam Cloud keeps your settings and progress with you between machines.

One price, the whole game.
