4) TACKLING: To tackle for possession of the bladder, the piece carrying the bladder may be challenged by placing two pieces on any of the eight squares adjacent to it (see fig. 5). The bladder is then placed on the head of either (player chooses) of the two pieces used to tackle. Successfully tackling for possession of the bladder concludes the players' turn, the game now continues as before. Remember, 'laming' the bladder carrier (as described in Rule 3) automatically transfers possession of the bladder as well.
