You know exactly why.
Considering the situation with new COVID-19 infections, the health and safety of participants and related parties is being put first, and thus “Yu-Gi-Oh! World Championship 2021” has been cancelled.
We sincerely apologize to everyone who looked forward to the event.
Due to the cancellation of the event, “Yu-Gi-Oh! Official Card Game / Trading Card Game” is planning large-scale online tournaments for each country and region, while “Yu-Gi-Oh! Duel Links” is planning a large-scale online tournament. We will inform you via official channels in the future about further details.
