NBA format explained: How the regular season, NBA Cup, Play-In tournament and Playoffs work

The NBA season runs across eight months and five distinct competitions, from the first tip-off in late October through to the NBA Finals in June, and understanding how each stage fits together is the fastest way into one of sport's most watchable leagues.

The 2026-27 season - the NBA’s 81st - begins on October 20, when Detroit Pistons take on Boston Celtics at Little Caesars Arena.

The Regular Season

Every team plays 82 regular-season games between October and April, producing a total of 1,230 scheduled matches across the league.

The 30 clubs are split evenly between the Eastern Conference and the Western Conference, with 15 teams in each.

Both conferences are divided into three divisions of five teams: the East holds the Atlantic, Central and South-East divisions, and the West holds the Northwest, Pacific and South-West divisions.

Division titles carry no special playoff seeding value - only the conference standings table determines who advances and in what order.

The top six teams in each conference by win percentage automatically qualify for the first round of the playoffs when the regular season concludes on April 11, 2027.

Teams finishing seventh through tenth in their conference enter the Play-In Tournament, and any team finishing 11th or below is eliminated from postseason competition entirely.

The Emirates NBA Cup

The Emirates NBA Cup is a separate in-season tournament that runs within the regular-season schedule, reaching its Final on December 11 at Hinkle Fieldhouse in Indianapolis.

The concept mirrors what European football’s domestic cups do alongside their league seasons, though the NBA version integrates most of its games directly into each team’s 82-game record rather than scheduling them as additional fixtures.

All 30 teams are drawn into six groups of five - three groups per conference - seeded by last season’s standings, ensuring the strongest teams do not all end up in the same group.

Group-stage games take place on designated Cup Nights from October 30 through November 27, and every one of those results counts toward a team’s regular-season win-loss record.

The group winners and the two best runners-up from each conference advance to an eight-team knockout stage, giving 16 clubs a route to the tournament’s later rounds.

The Quarterfinals and Semifinals are also counted as regular-season games, meaning teams have a direct competitive incentive to progress beyond the group stage even if they are not the favourites to lift the trophy.

The Championship Final is the only game in the competition that does not count toward regular-season records - it is a standalone, winner-takes-all match.

The New York Knicks became the first team in the Cup’s history to win the in-season tournament and the NBA Finals in the same season, defeating the Spurs in the December final and again in the June showpiece to complete a unique double.

The Play-In Tournament

The Play-In Tournament is a four-day competition played immediately after the regular season, used to decide the seventh and eighth seeds in each conference before the playoffs begin.

Eight teams in total are involved - seeds seven through ten from both the East and West - with each team’s season depending on single games rather than series.

The seventh and eighth seeds face each other first in each conference: the winner goes straight into the playoffs as the seventh seed, while the loser receives a second chance.

Simultaneously, the ninth and tenth seeds play each other: the loser of that game is eliminated and enters the NBA Draft Lottery, while the winner stays alive.

The decisive game in each conference is between the loser of the 7/8 matchup and the winner of the 9/10 matchup - the winner takes the eighth playoff seed, and the loser is done for the season.

The format means that a team finishing seventh or eighth still faces genuine elimination risk despite carrying a better record than their final opponent across 82 games.

The Play-In debuted as a temporary experiment during the 2020 bubble season in Orlando and became a permanent fixture from 2021 onwards.

The Playoffs

The NBA Playoffs feature 16 teams - eight from each conference - competing across four rounds, with every round a best-of-seven series.

The bracket is fixed the moment the Play-In ends and does not change: there is no reseeding after each round, so every team’s potential path to the Finals is set from the outset.

First-round matchups in each conference are determined by seeding: the first seed plays the eighth, the second plays the seventh, the third plays the sixth, and the fourth plays the fifth.

Every series uses the 2-2-1-1-1 home-court format: the higher seed hosts Games 1, 2, 5 and 7 at their own arena, while the lower seed hosts Games 3, 4 and 6.

The first team to win four games in any series advances to the next round, with a series ending anywhere between four and seven games.

The Conference Finals produce one representative from the East and one from the West, and those two winners meet in the NBA Finals.

The NBA Finals

The NBA Finals is a best-of-seven series between the Eastern Conference champion and the Western Conference champion, typically running from early June through to mid-June.

Home-court advantage in the Finals goes to whichever team had the better regular-season record - regardless of which conference they represent or what seed they carried into the playoffs.

All games in the Finals follow the same 2-2-1-1-1 structure used throughout the playoffs, with the home team hosting Games 1, 2, 5 and 7.

The New York Knicks won the 2026 Finals 4-1 against the San Antonio Spurs, with Jalen Brunson earning Finals MVP honours after scoring 45 points in the clinching fifth game - the Knicks’ first title since 1973.

All-Star Weekend

NBA All-Star Weekend is a standalone midseason event that does not affect regular-season standings or playoff seeding in any way.

The 2027 edition is scheduled for February 19 to 21 in Phoenix, Arizona.

Events across the three days include the Rising Stars game for first and second-year players, the Skills Challenge, the Three-Point Contest, the Slam Dunk Contest and the All-Star Game itself.

Player selections are made through a combination of fan voting, player voting and media voting, with the top vote-getters from each conference named as captains who then draft their own teams for the game.

Frequently Asked Questions

16 teams qualify - eight from the Eastern Conference and eight from the Western Conference. The top six in each conference qualify directly, and the remaining two spots per conference are decided by the Play-In Tournament involving seeds seven through ten.

What is the NBA Play-In Tournament?
The Play-In is a four-day knockout competition held after the regular season, used to decide the seventh and eighth seeds in each conference. Teams finishing seventh through tenth compete in three games per conference, with the seventh-seeded team needing only one win to secure a playoff spot.

How many games are in the NBA Playoffs?

How does home-court advantage work in the NBA Playoffs?
The higher-seeded team hosts Games 1, 2, 5 and 7 while the lower seed hosts Games 3, 4 and 6 (the 2-2-1-1-1 format). In the NBA Finals specifically, home court goes to the team with the better regular-season record, not necessarily the higher seed.
