What is the minimum number of teams needed for Team and Two-Headed Giant events?

In Team and Two-Headed Giant events, the format requires a minimum number of teams for proper gameplay structure. For Team events, which typically consist of teams of three players each, at least four teams are needed. This allows for meaningful matches, including a complete round of matchups where each team can compete against another team.

In Two-Headed Giant events, which involve two players teaming up against another pair, the format also benefits from having a minimum of four teams. This ensures that there are enough participants to form two viable matchups, allowing for a round-robin style of play where each team has the opportunity to play multiple games.

Thus, four teams provide the necessary structure to maintain competitive integrity and a smooth event flow, making it the key threshold for both team formats.
