Bollwerk 178
Bollwerk 178 is a unique variant on a board with 178 squares. The goal of the game is, occupying the opponent’s end field with a piece or a bomb. Whoever captures all his opponent’s pieces or immobilizes their opponent also wins. There is no King in this variant.
Each player has 20 pieces and 25 supplementary stones at their disposal. The game board is in a constant state of change due to the supplementary stones.
Over 3000 moves are available for just the first move, so that opening theory plays no role at Bollwerk 178.
Setup
Pieces
Guard:
Both players has 10 guards at the start of the game. Guards can move and capture one square forward vertically or forward diagonally. They can also move one square horizontally, but without being able to capture.
Guards can jump over their own guards as often as they like in all directions per move (this also allows them to move backwards).
They can also jump over an opponent’s guard, which is always captured (only possible forward vertically and forward diagonally as with normal capturing).
From their starting row they can also move two fields forward (vertically and diagonally), but without being able to capture.
Guards are blocked by all supplementary stones.
The red square means that this piece is the starting point when the options are displayed.
Guards place supplementary stones within their regular range of movement, but at most over one of their own guards (in all directions).
Forward vertically and forward diagonally, supplementary stones can also be placed over an enemy guard.

<p>Example for point 2.<br />
A player moves his King´s Knight. He then has the option to place an supplementary stone from the new square it’s on. This is possible on all squares the King´s Knight could reach from his new position the next turn.</p>
<p>Example for point 3.<br />
The player also has the option of not moving his King´s Knight and leaving it on its square. From there, the player can place an supplementary stone on a square that the King´s Knight can reach from his position.</p>
<p>A King´s Knight therefore places supplementary stones as part of his regular moves. There are exceptions for other pieces (Guard, Cannon, Spy).</p>
<p>It is not allowed to place supplementary stones in your own end zone. The attacking player may place supplementary stones in the opponent’s end zone. The defender can blow them up with a bomb or remove them using the knigh</p>
