Three Men’s Morris
The smallest and oldest member of the Mill game family, played on a 3×3 grid with three pieces per side. Unlike the larger Morris games, Three Men’s Morris has no sequential placement phase — pieces are placed and can immediately jump to any empty square on subsequent turns. The game is essentially Tic-Tac-Toe with mobile pieces, preventing draws through the ability to rearrange your position.

Setup
The board is a 3×3 grid of points, connected horizontally, vertically, and (in most versions) diagonally. The board begins empty.
Phase 1 — Placement
Players alternate placing one piece per turn onto any empty intersection until each player has placed all 3 pieces.
If a player forms a three-in-a-row during placement, they win immediately.
Phase 2 — Movement
Players alternate moving one piece per turn. A piece may move to any empty intersection on the board — not just adjacent ones. This teleportation distinguishes Three Men’s Morris from all larger variants.
The goal is to form a three-in-a-row (row, column, or diagonal, depending on board variant). On a diagonal-connected board, eight possible mills exist.
Winning
The first player to have all three pieces in a straight line (row, column, or diagonal) wins.
Draw Prevention
The free movement (jump anywhere) mechanic means that — unlike Tic-Tac-Toe — Three Men’s Morris very rarely draws, because positions can always be rearranged. A draw occurs only if the same position repeats three times with the same player to move.
