On the official tourism website of Seoul, South Korea, 'VisitSeoul', there is an event specially organized for foreign visitors
This event is in the form of a simple quiz where you answer a few questions related to Seoul — no need to be an expert on Seoul, as it's very beginner-friendly.
There are also helpful hints that you can see right away.
The event runs from November 13 to December 6, giving you the chance to answer different questions each day. Prizes include a total of 4 grand prize winners who will each receive two round-trip tickets (8 tickets in total), as well as 88 additional winners who will receive Alipay shopping vouchers worth 188 RMB each.
Even participating in just one quiz gives you a chance to win the round-trip tickets, but your odds of winning increase the more quizzes you take.
Also, if you've been to Seoul before, clicking the "If You’ve Been to Seoul" button and joining the "The World I Felt in Seoul" event is another way to boost your chances of winning.
