Ploy

In Ploy, the familiar chess pieces are replace by a "Commander" along with "Lances", "Probes" and "Shields". The game is played on gridlines and all pieces can move horizontally, vertically or diagonally. (Lances can move three spaces, Probes move two and Shields and the Commander only one.)

While any piece is capable of moving in any direction, they are limited as to which directions they can move in at any one time. Each piece bears a little "fin" which acts as a "direction indicator". Pieces can only move in a direction indicated by their direction indicators. On their turn, a player can move one piece in any direction allowed by its direction indicator or they can rotate a piece so that its directon indicators point in a different direction.

Pieces are captured by moving onto them as in chess. A player is out of the game when they have lost their Commander or all of their Lances, Probes and Shields. There are both two and four player versions of the game.
