It is played at the venue of the team with home-court advantage for the series, according to the playoff format arrangement. If a series reaches the sixth game, the requirement of a game seven is unknown until the conclusion of game six is established. However, if you are playing in a best-of-seven series and lose three games, you will need to win one more game to advance to the next round. The most recent game seven was on May 13, 2017 in Boston between the Celtics and the Bucks. It was also the first ever game seven in Boston. The outcome of the game determined who would go to the Eastern Conference Finals against the Cavaliers. The Celtics won that game four to reach the 2018 NBA Championship game. There have been many game sevens in National Basketball Association (NBA) history.
