How basketball works at the Olympics:
- There are 12 teams in both the men's and women's competitions. Both feature two groups of six teams.
- The men's draw is (with three places to be confirmed at Olympic qualifying tournament):
Group A: Argentina, France, Tunisia, United States, Qualifier 1, Qualifier 2.
Group B: Australia, Brazil, China, Great Britain, Spain, Qualifier 3.
- The women's draw is:
Group A: Angola, China, United States, Czech Republic, Croatia, Turkey
Group B: Australia, Brazil, Great Britain, Russia, Canada, France
- In the group stage, each country plays every other team in their group once.
- At the completion of the group stage, the top four teams from each group progress to the second round. From that point on the tournament becomes a knock-out competition.
- The top qualifying team crosses over to play the fourth-ranked team from the opposite group. The second-ranked team faces the third ranked team from the opposite group.
- The four winners progress to the semi-finals. The two winners then meet in the gold medal match, while the two defeated nations play off for the bronze medal.
- Basketball is played in four periods of 10 minutes each at the Olympics.
- Teams have five players on the court at any one time.
- Five-minute overtime periods follow if a game is tied at the end of four quarters.
- Teams score two points from inside the three-point line, three points from outside the three-point line and one point for each successful free-throw.
