In ice hockey, the area where the puck is put into play is known as the face-off circle. This circle is located at various points on the ice, including at the start of periods, after goals, and when play is stopped. The face-off involves players from both teams battling for control of the puck as it is dropped by the official. Mastering the face-off is crucial, as it can determine immediate possession and influence the flow of the game.
