In the NBA, basketball games include the preseason, regular season, playoffs, and finals. The normal NBA games each season are often referred to as the "regular season", with a total of 82 regular season games per team. The NBA has two halves, east and west, and each half is divided into three divisions. Five teams from the same division play four round-robins, which means that every two teams play four games, two home and two away. For example, the Rockets and Spurs, both in the Western Conference and Southwest Division, have met four times in the same regular season season. Two teams in the same half of the region will play 3~4 games, which is determined by the NBA headquarters depending on the highlights of the game. For example, the Spurs and Lakers are in the same half of the West, but they are in two different divisions, and the two teams may meet three or four times. Two teams in different halves play two matches, one home and one away. For example, the Spurs in the West and the Pistons in the East can only play two games in the regular season. Before the start of the regular season, due to the personnel adjustments of some teams, in order to facilitate the run-in of the team, the NBA usually arranges some preseason games, which are equivalent to what we call warm-up games, and the preseason results are not counted in the team's regular season results. After the regular season, the top 8 teams in each half of the division play the playoffs, which are played in a best-of-seven format. This season, the first place in the three divisions and the other five teams with better results in the regular season will play the playoffs until the East and West champions are determined, and finally the East and West champions will play in the finals
