A 9×9 square checkered board is used. Alternatively, an 8×8 square grid can be used with pieces played on the intersection points. Each player has a set of nine chess knights in their own color.

Players decide who is White, who is Black, and who moves first. Players alternate turns. Knights are initially set up on each player's first rank.

• Knights move or capture exactly as chess knights.
• On a player's turn, a knight can move to an empty square, or capture an enemy knight. A knight on the central square (e5) may be captured by the opponent.
• The player first to move a knight to the central square of the board (e5), and then leave that square on a subsequent move, wins the game. An alternative way to win is to capture all the opponent's pieces.

Example of zugzwang. The player to move either must occupy the center, or move a knight away. Both cases end in losing.

Occupy the central square if and only if you have strictly more knights attacking that square. If you have fewer knights than your opponent attacking the central square, you should equalize the number of your knights attacking it to avoid losing.
