All the nations have played at least one match.
The tournament started with Canada v China. The hosts won with a penalty, kicked by captain Christine Sinclair in stoppage time. That match also saw the tournament's first yellow card, to Deriree Scott. It also attracted the biggest crowd - 53,058.
In the other match in the group Netherlands had a 1-0 win over New Zealand after Lieke Martens scored with a long shot in the 33rd minute.
Norway started this group with a 4-0 win over Thailand, after goals by Trine Rønning, Isabell Herlovsen (2) and Ada Stolsmo Hegerberg. We also saw the tournament's first missed penalty, when Maren Mjelde's kick was saved by Thai keeper Boonsing. This match was the most widely viewed football match in Norway this year.
In the second match Germany had a 10-0 win over Ivory Coast, the World Cup's second highest win in history behind Germany-Argentina 11-0 in 2007. There were goals by Celia Sasic (3), Anja Mittag (3), Simone Laudehr, Sara Däbritz, Melanie Behringer and Alexandra Popp. Germany became the biggest scorers in World Cup history with 101. Sasic scored the tournament's first hat trick and the quickest-ever hat trick in World Cup history.
Cameroon ran rings round Ecuador in the first match. At the end it was 6-0 with goals by Madeleine Ngono Mani, Gaelle Enganamouit (3), Christine Manie and Gabrielle Onguene. The match saw the first red card, when Ecuador's captain Ligia Moreira was sent off in the 66th minute. Enganamouit's hat trick was the 17th in World Cup history.
The champions Japan met Switzerland in the second match. The Japanese won it 1-0 after a goal by Aya Miyama, a penalty in the 29th minute.
We quickly saw why this is called the group of death. Sweden-Nigeria was a real thriller. Sweden led 2-0 and 3-1, but Nigeria came back and it ended in a 3-3 draw. This match had the first own-goal, from Desire Oparanozie in the 21st minute. Linda Sembrant and Nilla Fischer scored for the Swedes while Ngozi Okobi, Asiat Oshoala and Francisca Ordega scored Nigeria's goals. This was the first match without a card being given.
The other match was between title favourites USA and Australia. The USA won 3-1 in the end after goals by Megan Rapinoe (2) and Christen Press. Lisa De Vanna scored Australia's goal. USA's three goals brought them level with Germany on a total of 101.
Spain played a 1-1 draw with Costa Rica. Vicky Losada scored after 13 minutes while Raquel Rodriquez Cedeno equalised a minute later.
Brazil beat South Korea 2-0 in the other match. Formiga scored first, before Marta scored her 25th World Cup goal with a penalty. She became the highest scoring player in World Cup history. Formiga's goal also set another record - she was the oldest player ever to score at the World Cup Finals, at 37 years 98 days.
France took a 1-0 win over England with a goal by Eugenie Le Sommer of Olympique Lyonnais.
In the other match Colombia drew 1-1 with Mexico. Veronica Perez scored for Mexico and Daniela Montoya equalised for Colombia.
The first 12 matches have seen 40 goals scored. 27 yellow cards and one red have been given. Sasic (Germany), Mittag (Germany) and Enganamouit (Cameroon) have all scored three goals.
Brazil's Formiga and Japan's Homare Sawa are competing at the World Cup for the sixth time. Solveig Gulbrandsen of Norway is at her fifth.
