Flower cards were invented in Japan, possibly in order to circumvent laws against playing with conventional 4-suited card decks. Nowadays, however, it is in Korea that games with flower cards are most popular. The best known Korean flower card game is Go Stop(맞고，こいこい), which like most Japanese flower card games is a fishing game.
Players capture cards from a central layout by playing a card of the same month (flower). The aim is to collect scoring combinations among the cards captured. When a players captures have a sufficient value, the player can stop the game and claim payment, or can continue the game (go) in the hope of winning more, but risking that an opponent will win meanwhile. It is this decision to stop or go that gives the game its name.
