Canada's Jennifer Jones the top seed after finishing round-robin undefeated.
North Bay, Canada - Although they were not on the ice, Czech Republic were the main beneficiaries of what happened in Friday evening's 20th and last round-robin session of the Ford World Women's Curling Championship 2018 in North Bay, Canada.
The combination of results meant that they took the last available slot in the weekend's playoff games - joining already qualified Canada, Sweden, Korea, Russia and the United States.
Canada's Jennifer Jones defeated Jamie Sinclair of the United States 8-5, riding a thin angle-run in the second end for three to an early lead, then grabbing another three in the eighth end to seal the victory.
"We've had a pretty consistent week and made a lot of big shots when we had to and hopefully that streak can continue into the playoffs," said Jones. "Anytime you can play at a world championship is a dream come true and if you get to stand on the podium it's truly unbelievable, so hopefully we will get that chance to play in the final."
Russia's Victoria Moiseeva clinched the 4th seed with a 10-5 win over Denmark, a win that also helped idle Czech Republic claim the final playoff spot, sliding into the 5th playoff seed.
Moiseeva was in a back and forth battle with Denmark until they stole two in the sixth end, then added another steal of two in the ninth end for handshakes and the win.
"It was a tough loss before that game and we really needed to come back to ourselves and feel the confidence again," said Moiseeva. "We had some problems in the previous game and we tried to repeat these shots to perfect some things."
Second-placed Olympic champions Sweden (8-5) and third-placed Olympic silver medallists Korea (6-5) both lost to Scotland on the final round-robin day. The Czech Republic had to play their last game round-robin without unwell skip Anna Kubeskova, with normal second player Tereza Pliskova stepping up. They lost this game by 7-5 to Japan and then had to sit out and watch the last session unfold before being assured of their place in the playoffs.
The United States qualified in sixth place despite losing their last two games - by 8-6 to the Czechs and then by 8-5 to Canada. China's 7-6 win over Germany in the last session meant they shared the same won six, lost six records as the Czech Republic and the United States, but they lost out on a play-off place because both of these teams had beaten them earlier in the round-robin.
With the round-robin now concluded, table-toppers Canada and the second-placed Olympic champions from Sweden move directly into separate semi-finals on Saturday. Canada and Sweden's opponents will be determined by the results of the two qualification games beforehand, in which third-placed Korea will play the sixth-placed United States, and fourth-placed Russia will face the fifth-placed Czech Republic.
