Attangle is an abstract stacking game for 2 players. This last game concludes Dieter Stein's Stacking Game Trilogy.


object of the game

The game is won by the player who can build 3 triple stacks.

sequence of play

Figure 1 – Initially the board is empty.

Players choose their color and place a stock of 18 pieces in front of them. White makes the first move. Then turns alternate.

During the game players enter new pieces and build stacks of pieces through capturing moves.

A player controls a stack if he owns the topmost piece. A stack can never be split.

Generally a player can either:

Players cannot pass their turn. If the stock is empty a player must make a capture move or otherwise resign the game.

Generally, a capture move is a movement of two different pieces on the board and stacking up on an opponent piece. After that the current player takes back the topmost piece (which will be always of his color) to the stock. The maximum height of a stack (after taking back one piece) is three. It follows that there are three possible capture moves:

As a rule of thumb just remember: looking at the three pieces (or stacks resp.) of a capture move, only one double stack can be involved.

Pieces always move in a straight line and any number of unoccupied spaces. It is allowed to cross the center d4. Triple stacks cannot be moved.

Figure 2 – Two single pieces capture a single opponent piece.

Figure 3 – Double stacks can be captured.

Figure 4 – Stacks can capture too.

Figure 5 – White or black: no captures possible.

end of the game

Figure 6 – White resigns. The (indicated) threat by black cannot be answered.

A game is won by the player who builds up his third triple stack. Also, a player must resign if he has an empty stock and cannot make a capture move. - an Abstract Board Game. Copyright © 2005-2017 Dieter Stein.
