Quick Pitch

Twelve Men's Morris uses four concentric squares connected by lines, creating 32 intersection points.

Equipment Needed

The Board

Four concentric squares with connecting lines:

1 — 2 — 3 — 4
|           |
5   6   7   8
|   |   |   |
9   10 11   12
|   |   |   |
13 14 15   16
|           |
17 — 18 — 19 — 20
(And outer three squares: 21-24, 25-28, 29-32)

The board has 32 intersection points arranged in four concentric squares.

Improvising the Board

  1. Drawn board: Draw four concentric squares on large paper or cardboard, connect corresponding points with lines
  2. Multiple boards: Play Nine Men's Morris on two separate 24-point boards simultaneously
  3. Carved board: Carve the pattern into wood (requires significant effort)

Pieces

  • 24 pieces total: 12 per player
  • Two colors or types to distinguish players

Setup

  1. Draw the large board with four concentric squares
  2. Each player takes 12 pieces
  3. The board starts empty
  4. Designate first player

Rules

Phase 1: Placement (First 12 Moves Per Player)

  1. Players alternate placing one piece on an empty intersection
  2. If you form a mill, immediately capture one opponent piece
  3. Continue until both players have placed all 12 pieces

Phase 2: Movement (After Initial Placement)

  1. Move one piece to an adjacent empty intersection
  2. If you form a mill, capture one opponent piece
  3. Continue until one player is reduced to 3 or fewer pieces (you win), or the game becomes locked

Mills

Three of your pieces in a straight line along the board's lines. Diagonals do not count as mills.

Capturing

When you form a mill, remove one opponent piece from the board. You cannot capture a piece that is part of an opponent's mill, unless the opponent has no other pieces.

Tips

Opening Phase

  • Outer square dominance: Control outer edges early
  • Build toward center: Position pieces to move toward more valuable central positions later
  • Avoid early commitment: Don't form mills immediately; build threats instead

Middle Game

  • Controlled reduction: Gradually reduce opponent through mill captures
  • Central control: The innermost square is most valuable in middle game
  • Dual threats: Position pieces to threaten multiple mills simultaneously

Endgame

  • Three-piece positions: When reduced to 3 pieces, standard movement applies
  • Piece placement: Keep pieces connected to form mills or prevent opponent's mills

Variations

Simplified Twelve Men's Morris

Play on a board with only three concentric squares (24 points) with 8 pieces per player—essentially a larger Nine Men's Morris.

Quick Twelve Men's Morris

Victory condition: First to reduce opponent to 6 pieces (not 3), reducing total game time.

History & Origins

Twelve Men's Morris is a medieval European game from the extended Morris family, documented in historical records as a regional variant developed in certain areas of Europe. The game represents the upper end of the Morris game progression, with larger boards and more pieces than Nine Men's Morris. Historical evidence suggests that various European regions developed their own versions of Mill games, including these expanded variants with 12 or more pieces per player.

Cultural Context

Twelve Men's Morris represents the extended end of the mill game family and appeals to players enjoying longer strategic games with greater complexity. The game exemplifies medieval European gaming traditions and demonstrates how game designers created progression from simple (Three Men's Morris) to complex (Twelve Men's Morris). The game remains popular in traditional gaming circles and is sometimes used in competitive mill game championships across Europe.
