Go-Stop is a traditional Korean card game played with a deck of hwatu cards. The game involves two players who aim to collect sets of cards to score points. Players take turns drawing cards and can either "go" to continue playing or "stop" to end their turn and score points based on their collected cards. The game is known for its fast pace and strategic elements, as players must decide when to take risks. Scoring can vary, with players earning points for specific combinations of cards. Go-Stop is popular in social settings and often played for fun or small stakes.
