Nine Men's Morris

Quick Pitch

Nine Men's Morris is a two-player strategy game where you place and move pieces to form "mills" — three in a row — which let you capture your opponent's pieces. Reduce them to two pieces to win.

Hook

The game has two completely different phases: first, you take turns placing your nine pieces on the board, trying to line up three in a row while blocking your opponent from doing the same. Once everyone's pieces are down, the real maneuvering begins — sliding pieces along the lines, opening and closing mills, and slowly chipping away at your opponent's army. It looks simple, but Nine Men's Morris has been played and studied for over a thousand years for good reason.

Equipment Needed

The Board

Nine Men's Morris is played on a distinctive board with three concentric squares:

• 24 intersection points (called "points" or "spaces") arranged in three concentric squares
• Lines connecting the points, showing which movements are allowed
• Each point can hold one piece

Traditional board:

1 — 2 — 3
|   |   |
4 — 5 — 6
|   |   |
7 — 8 — 9

10 — 11 — 12
|    |    |
13 — 14 — 15
|    |    |
16 — 17 — 18

19 — 20 — 21
|    |    |
22 — 23 — 24
|    |    |
25 — 26 — 27

Improvising the Board

1. Drawn board: Draw three concentric squares (or rectangles) on paper or cardboard; connect corresponding points with straight lines. Mark the 24 intersection points clearly.
2. Sand/earth version: Draw in sand or dirt with a stick; mark points with small stones
3. Carved board: Carve the squares and lines into soft wood
4. Cloth version: Draw on cloth or canvas for a portable board

Pieces

• 18 pieces total: 9 per player
• Two colors/types: To distinguish players (e.g., light and dark stones, two different colored tokens)
• Options: Pebbles, beads, coins, buttons, or any 18 identifiable objects (9 of one type, 9 of another)

Setup

1. Draw or place the board between the two players
2. Each player takes 9 pieces of their color
3. The board starts empty
4. Designate who plays first (traditionally by mutual agreement)
5. Players alternate turns

Rules

Nine Men's Morris has three distinct phases:

Phase 1: Placement Phase (First 9 Moves Per Player)

During the placement phase, players are placing their pieces on the board rather than moving existing pieces.

On Your Turn During Placement:

1. Place one of your pieces on an empty point on the board
2. If you form a "mill" (three of your pieces in a straight line), immediately capture one opponent piece from the board (see Capturing below)
3. If capturing, remove one opponent piece from play
4. Opponent takes their turn

Special Rule for Capturing:

• You may remove any opponent piece from the board when you form a mill
• Exception: You cannot remove a piece that is part of an opponent's mill, unless that is the only option available

Placements continue until both players have placed all 9 pieces.

Phase 2: Moving Phase (After Initial Placement)

Once all pieces are placed, players move pieces on the board rather than placing new ones.

On Your Turn During Moving:

1. Move one of your pieces from its current point to an adjacent empty point (along the connecting lines only; no diagonal jumps)
2. If your move completes a mill, immediately capture an opponent piece
3. If you form a mill, remove one opponent piece from the board
4. Opponent takes their turn

Continued Placement: If a player is reduced to 3 or fewer pieces, that player may optionally move pieces as normal OR place a piece (if they somehow captured pieces and later have new pieces to place—rarely occurs).

Phase 3: Flying (Optional Late-Game Rule)

If a player is reduced to exactly 3 pieces, they enter a special "flying" phase:

Flying Rules:

• A player with 3 pieces may move to any empty point on the board, not just adjacent points
• This allows desperate players to potentially form new mills and capture their way back into the game
• Opponent continues normal movement rules

Not all rule sets include flying; check with players before assuming this rule applies.

Capturing: The Mill Rule

What is a Mill?

• A mill is exactly three of your pieces in a straight line
• Lines include the outer square, middle square, inner square, and the lines connecting squares at cardinal points
• Diagonal pieces do NOT form mills

When You Form a Mill:

• Immediately capture one opponent piece from the board
• Remove the captured piece permanently from play
• The captured piece cannot be placed again

Capture Restrictions:

• You cannot capture a piece that is part of a mill, unless the opponent has no pieces outside a mill
• If opponent has pieces outside mills, you must capture those

Game End

Winning Conditions:

1. Opponent has fewer than 3 pieces: You win immediately (opponent cannot move)
2. Opponent cannot move: If opponent's remaining pieces are blocked (no adjacent empty spaces), you win
3. Game becomes static: If no mills are formed and pieces are locked, players may agree to a draw

No Mills Phase: If neither player can form a mill, the game may reach a locked position where only pieces still on the board block movement. These positions are often draws.
