Kampf is played by two players on a board that is divided into 81 equal-sized, alternating black and white squares and has a dash-dotted line.
There are a total of 36 pieces in the game: 18 white and 18 black, which are set up as two armies to fight against each other. Each of the two armies is made up of ten higher combat pieces (2 planes, 2 submarines, 2 airships, 2 tanks, 1 flag, 1 general) and eight soldiers.
The aim of the fight is to force the opposing party's main piece, the flag, to surrender.
The different pieces have different rules for movement and capturing. Each player may only move one piece at a time. A piece that is touched must be moved. You can only capture one piece at a time with each move. The capturing piece is always placed on the square of the captured piece. All main pieces (except the soldiers, who can only move and capture in a forward direction) can move and capture forwards and backwards.
If an attacking piece could be captured by an enemy piece after it has captured, the attacked piece is considered to be covered. Covered pieces may not be captured. If a piece attacks the enemy flag, i.e. if it makes a move which would enable it to press the enemy flag on its next move, this attack move must always be accompanied by the cry "Kampf" so that the opponent is made aware of this attack.
