Squid Game is the South Korean Netflix series released in 2021, created by Hwang Dong-hyuk, in which indebted contestants compete in childhood games for a cash prize. Red Light, Green Light is the first game in the series, based on a traditional playground game where players advance on one call and freeze on another. Clips from the episode spread rapidly on TikTok and YouTube as the show became a global hit, and the rules announcement was reused in challenges, parodies and game recreations far beyond the original scene.
