Game Rules

Objective of the Game

The game is played on a board sized 11×11, 13×13, 15×15, or 17×17. In the center stands the King with his Defenders (white). The Attackers (black) stand at the edges of the board.

• The King wins when he reaches a corner square.
• The Attackers win when they surround the King from TWO sides (horizontally or vertically).

Setup

The King is in the center. Defenders form a diamond around the center:

• 11×11 → diamond out to distance 2 from the center
• 13×13 → out to 3, 15×15 → out to 4, 17×17 → out to 5

Attackers stand at the edges of the board in two rows, 3 squares from the corners.

Movement of Pieces

All pieces (including the King) move like a rook in chess — any distance horizontally or vertically.

• Pieces cannot jump over others.
• Diagonal movement is not allowed.

Capturing Pieces

A piece is captured when it is sandwiched between two of your pieces in the same row or column. This applies even to the King.

• It is enough to surround from TWO opposite sides (horizontally/vertically).
• Diagonal “sandwiching” does not count.

End of the Game

• ✔ The King reaches a corner → victory for the Defenders.
• ✔ The King is surrounded from two sides → victory for the Attackers.

• The last move is highlighted: from = dark red, to = dark green.
• The selected piece has its square highlighted in dark blue.
