Bowls have symbols unique to the set of four for identification. The side of the bowl with a larger symbol within a circle indicates the side away from the bias. That side with a smaller symbol within a smaller circle is the bias side toward which the bowl will turn. It is not uncommon for players to deliver a "wrong bias" shot from time to time and see their carefully aimed bowl crossing neighbouring rinks rather than heading towards their jack.
