- Each conference's Nos. 7 and 8 teams will face off, with the winner earning the No. 7 seed in the playoffs. The loser will still have one more opportunity to reach the playoffs.
- Each conference's Nos. 9 and 10 teams will face off, with the winner advancing to play the loser of the No. 7-vs.-No. 8 game. The loser of the No. 9-vs.-No. 10 game will be eliminated from playoff contention.
- The loser of the No. 7-vs.-No. 8 game and the winner of the No. 9-vs.-No. 10 game will then play against each other. The winner of that game will be the No. 8 seed in the playoffs. The loser will be eliminated from playoff contention.
- Beyond the play-in tournament, the 2021 NBA playoffs will follow the typical format, with full best-of-seven series all the way through the NBA Finals.
