Cookie Run Kingdom summary: Cookie Run, a mobile game, has been adapted into an edutainment app that teaches Hanja, the Chinese characters used in the Korean language. The app is set in an alternate universe where running, playing and Hanja have been banned due to safety concerns, and the temperature of the country is rapidly increasing due to a volcano eruption. A group of daring Cookies seek the guidance of past champions, known as elders, to learn Hanja and collect pets.
