Quiz 2020 has a fresh twist for a quiz show: combining it with the guessing game. The show quiz the contestants on things people may have thought about once in their lives. If a contestant answers the question, he/she gets the prize for the donation under his/her name. Hosted by Jeon Hyun-moo and Boom, the show features eight celebrities as the contestants. There is one twist: one of eight knows the answer to the question. Remaining celebs have to answer the questions and find the one who knows everything.
