In this post, I am going to introduce you another activity the koreans are fond of. It is called 인형뽑기 (read inhyungPpopki), literally claw machine game.
Nowadays it is really popular, even if it already existed before. I think the gain of popularity of those claw machine games is because (or thanks to) the currency in Korea. A lot of people are paying in cash and therefore, they also have a lot of 1,000 bill to spend, or even 500won coins.
Also, it is a kind of competition with the machine and with others, and Korea is a really competitive society. Boys also spend a lot of money on those machines to impress their girlfriends.
Usually machines go from 500 won one round to 1,000 won one round. You will have between 15 seconds and 30 seconds to pick the price. Of course, it will be easier to buy it in stores, but nothing can replace the thrill of picking your wanted doll out of the machine.
