What is an Ideal Type Tournament?

An ideal type tournament (also known as "이상형 월드컵" in Korean) is a popular online game format where participants choose between two options in each round until a final winner is selected. Originally popular in Korea, this format has become a beloved way for K-POP fans to rank their favorite idols and share results with friends.
