There are 82 games in the regular season. The two conferences, Eastern and Western, determine ultimately who will play in the Finals. During the regular season, each team plays the majority of their games against their own conference with a large fraction being against teams in their own division. There are three divisions per conference. At the end of the regular season, the top 8 teams from each conference get into the playoffs, and will play the other teams in the conference to make it to the Finals against the opposite conference's top team.
