 Apart from the Flag (the Philippine Flag) and the Spy (a pair of prying eyes), the rank insignia of the pieces used in the game are those used in the Philippine Army.The playing pieces are identical-sized plastic or metal flat rectangles that are bent or molded at a 90-degree or 80-degree angle.The rank insignia are printed on the rear side to keep them hidden from the opposing player; the game requires that the front side of the pieces should have no distinguishing marks that will help identify the pieces.
