The top two teams in each men's and women's round-robin group will proceed to the quarter-finals along with the third-placed team with the best draw shot challenge.

The other third-placed teams will play a qualification game to determine the last quarter-finalist.

Competition is open to junior teams from all World Curling Federation Member Associations that have not already qualified for the 2017 World Junior Curling Championships in South Korean city Gangneung.

Round-robin action in Östersund is due to run through to Sunday (January 8).
