The top three teams in each division qualify for the playoffs. The next two best records in each conference also qualify as wildcard teams. The wild card team with the fewer points plays the team with the best record in the conference regardless of division. The other wild card team plays the other division winner. The wild card team then stays in that division's playoffs. The division semifinal winners meet in the division finals. The two division winners in each conference meet in the conference finals. The two conference winners meet in the Stanley Cup final. All series are best-of-seven.
