1. Regulation time consists of three periods of 20 minutes of game action, stop time.

2. Periods are separated by an intermission of 15 minutes.

3. Teams change ends to start each period.

4. The ice must be resurfaced prior to the start of each period (except 5- and 10-minute overtime periods).

5. Overtime follows the third period when the score is tied after 60 minutes of regulation time and can consist of a 5-minute period, 10-minute period, or 20-minute period. In each case, these periods are played on a sudden-death basis (next goal wins). The penalty- shot shootout consists of a specified number of shots per team, followed by a sudden-death penalty-shot shootout if the score in the shootout remains tied after these shots.
