The strategy game Zugzwang is the most popular human parlor game in the Federal Confederation. In this two-player strategy game, the aim is to either move all your pieces to the opponent's base line or prevent your opponent from doing so. The game is designed to be simple, resource-efficient, and sustainable, requiring only a small board and simple playing pieces.

Zugzwang“ is a term borrowed from the German language, meaning “compulsion to move.”

• A square game board with 5×5 squares, which could be drawn on paper, in the sand, or even etched onto a wooden surface.
• 5 game pieces for each player. These could be small stones, coins, or little wooden pieces.

The aim is to either move all of your pieces into the opponent's base line or block your opponent from doing so.

1. Players take turns placing one of their pieces onto any empty square. This continues until all pieces are on the board.
2. Once all pieces are placed, players take turns moving one of their pieces one square in any cardinal direction: forward, backward, left, or right. Diagonal moves are not allowed.
3. A piece can capture an opponent's piece by moving into its square. The captured piece is then removed from the board.
4. A move is mandatory; there is no option to “pass” a turn.
5. A piece that reaches the opponent's base line is safe from capture but remains on the board.
6. If a player is unable to make a valid move, they lose the game
