## 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.

### Components

| Item | Qty | Notes |
|------|-----|-------|
| **Board** | 1 | 3×3 grid of intersections (9 positions) |
| **Pieces** | 6 | 3 per player in contrasting colours |

### 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.
