Go Stop is a traditional Korean card game played with a deck of hwatu cards. The game is typically played by two to six players, and the objective is to collect sets of cards to score points. Players take turns drawing cards and can either keep them or play them to form combinations, aiming to reach a certain score to win. The game has two main phases: "Go" and "Stop." In the "Go" phase, players try to accumulate points, while in the "Stop" phase, they can choose to end the game if they believe they have enough points. The game is known for its strategic depth and social interaction among players.
