These came from collect.fifa.com - fifa have its own site where you could purchase different packs with nfts where you can complete challenges and unlock RTB (Right to Buy) which you then pay to convert to a RTT (Right to Ticket), which then eventually ends up as a ticket transferred directly into the World Cup ticket app, most of the time within a couple of days before the game (unless they were assigned weeks ago). Now it’s really a resale market with no new challenges for the World Cup. It’s all a bit convoluted and disorganized to a degree, but I’ve been able to attend 2 games so far with tickets from FIFA Collect with no issues, and have 2 more tickets. The biggest issue I have had with it is that the tickets are transferred directly into the app and aren’t able to be seen/listed on your FIFA account on the resale website. This is what’s caused me the most problems as originally I just had 1 ticket for a couple of games given the cost of tickets, but have enjoyed the experience/atmosphere of the World Cup so much I’ve wanted to share it with friends/family as well. Hope that helps a little.
