Object: Capture all opponents' sets by checkmating and capturing their Kings.

Forget almost everything you know about Chess other than how the various pieces move. In Prince Chess you are up against Three Opponents simultaneously. Every time you are weakened, Three Opponents gain an advantage on you. Because of this, it is not good practice to trade pieces with a single Opponent because although you have weakened that Opponent versus yourself, you have been weakened versus the remaining Two Opponents. Also, the value of your pieces is different in Prince Chess than in traditional Chess. Bishops are comparable to Rooks, especially early in the game because diagonal movements are easier to hide amongst the large quantity of pieces on the board and on the larger format board itself. There are also the Two Princes to contend with , the Prince Rook and the Prince Bishop, which are arguably as strong or stronger than the Queen. The Prince Bishop is capable of independently Checkmating an Opponent's King in an empty corner. Ultimately, the strength of the various pieces is dependent on your style. Beware of the single unprotected Pawn in the initial setup and leaving your King open to easy Checkmate by the sneaky Prince Bishop.
