- 37 resin playing pieces
- game board (11x11)
Board size and set up varies, 7x7, 9x9, 11x11, 13x13 or 15x15 squares.
Object of the Game
The dark pieces lay seige, their goal, to capture the king. The light pieces must break the seige and get their king to safety.
There are two players, the king's side vs attackers. There are twice as many attackers as defenders.
The attackers' side moves first, the players then take turns. All pieces move any number of vacant squares along a row or a column, just like a rook in chess.
Moving a piece.
All pieces except the king are captured if sandwiched between two enemy pieces, or between an enemy piece and a restricted square. The two enemy pieces should be on the square above and below or on the squares left and right of the attacked piece, i.e. not diagonally.
Capture of pieces.
Capture of pieces.
A piece is only captured if the trap is closed by the agressor's move, it is therefore permitted to move in between two enemy pieces.
The piece is not captured.
Restricted squares may only be occupied by the king. The central restricted square is called the throne. It is allowed for the king to re-enter the throne, and all pieces may pass through the throne when it is empty.
Restricted squares are hostile, which means they can replace one of the two pieces taking part in a capture. The throne is always hostile to the attackers, but only hostile to the defenders when it is empty. The board edge is NOT hostile.
On the 7x7 board:
Ard Ri: No throne square, i.e. there are no restricted squares on the board.
Brandubh: The four corner squares are also restricted and hostile, just like the throne.
King's Side Win
If the king reaches the edge the king has escaped and his side wins.
The king's side wins.
Brandubh - King's side win:
If the king reaches any corner square, the king has escaped and his side wins.
The king's side wins
The attackers win if they can capture the king.
The king is captured.
The king is captured like all other pieces, except when he is on or next to the throne.
On the throne, the attackers must surround him on all four cardinal points.
If on a square next to the throne, the attackers must occupy the three remaining squares around him.
If the attackers surround the king and ALL remaining defenders, then they win, as they have prevented the king from escaping.
The attackers win by
encircling all defenders.
Perpetual repetitions are forbidden
A player who agressively maintains a board repetition must find another move to break the repeti- tion, or lose the game.
The king must find another move.
If he can't or won't, he loses.
e.g. A player attacks by continually side stepping with a piece in order to find an open path to break through. The opponent continually brings his piece in line with the aggressive piece to block the open path.
The "aggressive player" is the one who has some choice in whether to repeat the pattern or not.
If a board position is repeated for the third time, "the aggressive player" loses the game.
If a player cannot move, he loses the game.
