Object: Get all your ducks in a row. Ducks move one or two spaces in any direction and can fly over an intervening duck.
 
Game play is characterized by multiple threats. The most useful multiple threat consists of three ducks in an orthogonal row, with an empty space on either side, and the fourth duck two spaces removed from the center duck (e.g., ducks on b4, c4, d4, and c2). The fourth duck can move to either end of the row to win the game. Even when the opponent successfully defends against a "T" formation by placing pieces on both ends of the 3-row, the formation is adaptable to a number of successive threats.
 
Multiple threats give the game its depth. While it may be easy to guard against a specific T-formation (or other initial threat), pieces are forced into defensive positions that may make the player vulnerable to successor threats. A more detailed treatment of game strategy can be found in the "strategy" section that comes with the game.
