Not surprising, though still disappointing for many folks
In light of the current coronavirus situation, along with putting the safety and health of all the participants and related parties first, the “Yu-Gi-Oh! World Championship 2021” has been cancelled.
We sincerely apologise to everyone who was looking forward to the event.
Due to the cancellation, the Yu-Gi-Oh! OCG and TCG, along with Yu-Gi-Oh! Duel Links will be planning large-scale online tournaments for each country and region. More details will be announced at a later date on the official website, social media and other channels.
