The 'Squid Game' Season 1 Cast: What to Remember About the Characters and Stars of the Netflix K-Drama

Would you risk your life playing kids' games if it meant winning a literal fortune? The thriller Korean drama Squid Game premiered on Netflix in September 2021, captivating audiences with its depiction of a brutal competition for 456 billion Korean won (about $38 million). Since its premiere, the dystopian social satire has become the streamer's most-watched show of all time, with the entire world following its cast of all-star Korean actors as they form alliances and enemies through deadly versions of Red Light, Green Light, and other children's games.
