 Each "game" is played in a three-on-three format (i.e., three skaters and one goaltender, unless affected by penalties) over a single 20-minute period (the same length of a period in a regular NHL game).Since its first season in 2013, the National Women's Soccer League has used a Shaughnessy playoff (using 1–4 and 2–3 semifinal pairings) to determine its champion.In NCAA college basketball, one Division I conference uses a Shaughnessy playoff for its postseason tournaments for men and women.
