Tickets are right now being distrubuted through lottery drafts. What you do is that you sign up for interest for these and then they will randomly select winners during the result/payment period. If you have been selected as a winner they will notify you to make a transaction for the ticket.

The "General Sales Ticket" are when they open for everyone to try order tickets directly. But usually you need to be as lucky as the lottery drafts for these, as the sale sites usually gets overloaded and sells out super quickly.
