Friendship Cup

Friendship Cup (フレンドシップカップ Furendoshippu Kappu) is a tournament held in the Synchro Dimension mentioned in the Yu-Gi-Oh! ARC-V. The tournament is said to have made Jack Atlas the current Duel King. It was created to promote harmony between the Tops and Commons after the Commons revolted when Chojiro Tokumatsu was arrested.

The name of the tournament is likely a reference to the Fortune Cup tournament in Yu-Gi-Oh! 5D's that formed a major story arc in the first season. Another similarity is the fact that Yugo, Dennis and Shay want to compete in such tournament for the chance to Duel against Jack, albeit for different reasons, as well as the main protagonist of their respective series being personally invited by the head of Security after escaping from prison.

Requirements
Within the Underground Dueling Arena, defeating 10 people in a row allows one to participate in such tournament. Alternatively, one can also sign up by filling an application sheet, which apparently needs to be approved by Jean-Michel Roger, though Jean may also invite people he deems worthy himself.

Tournament
The Friendship Cup is conducted as a 16-player knock-out tournament. The participants are locked in a building owned by the Executive Council to keep Jean-Michel Roger and Security from interfering. Matchups are determined on the spot with the remaining participants, with the chosen Duelists being released at that moment and led to the Duel Palace.
