Achi / Three Men's Morris Board

Nine points, three pieces each, two minutes a game

Three Men's Morris is among the oldest board games anyone can name. Two players, three pieces apiece, and one goal: get your three in a line.

What makes it more than noughts-and-crosses is that the board fills up. Once all six pieces are down, nobody can place anything new, so play switches to sliding pieces along the drawn lines to adjacent empty points. That second phase is where the game actually lives, and it is why a draw is much rarer here than on a tic-tac-toe grid.

Print the board, find two sets of coins, play. No app, no account, no setup beyond a printer.

Achi, Tapatan, and the same nine points

The names are regional. Achi is Ghanaian. Tapatan is played in the Philippines. Three Men's Morris is the European label, and the morris family it belongs to runs all the way up to nine men's morris on a much bigger board.

Rules vary slightly from place to place, but every version uses three pieces a side and a placing phase followed by a sliding phase, so one printed board serves all of them. Turn the centre diagonals on and you have the classic Achi and Tapatan lattice. Turn them off and you get the plain square-and-cross variant, which is a slower, more defensive game because there are fewer lines to make and fewer to block.

How to play it

Each player takes three pieces. Coins, buttons, or the cut-outs printed under the board.

Take turns placing one piece at a time on any empty point until all six are down. Then take turns sliding a single piece along a marked line to an adjacent empty point, one step, never jumping. The first player to get their three onto one straight line wins, whether that line runs across the board, down it, or corner to corner when the diagonals are drawn.

One piece of strategy is worth telling a child before their first game: take the centre. More lines pass through it than through any other point, and a player who holds it is involved in almost every threat on the board.

One board or four

A single board fills the page and is the version to print for a display or for small hands. Two to a sheet halves your paper. Four is a class set in one press, and the boards are still comfortably large enough to play on with 2p coins.

The rules block under the board is on by default and it earns its place: a pair of children can be playing without an adult explaining anything. The cut-out coins are on too, three per player, which removes the only remaining excuse for not starting.

Where these get used

Classrooms

A wet break, a maths logic station, or a lesson on ancient games. The printed rules mean you hand out sheets rather than run a briefing.

Families

Keep a couple folded in a bag. A game lasts about two minutes, it teaches blocking and thinking a move ahead, and it works at a restaurant table where a phone would not be welcome.

Folk-game collectors

A consistent, tidy board for the whole Achi and Tapatan cluster without hand-drawing the lattice every time.

What it will not do

This prints blank boards. It is not a game you can play on screen, it does not track moves, and it will not tell you who won.

There is also nothing random about the output, so there is no seed and no answer key: every board of a given setting is identical to every other, which is exactly what you want from a board and not at all what you want from a puzzle. Colours follow the shared brand template and cannot be changed per sheet.
