The Korean game played with these cards is more often referred to as Godori, or Go-stop. The Hwa-tu cards are approximately 1 3/8 wide by 2 1/8 high and are smaller and thicker than playing cards used in the West. The face of these plastic cards is glossy, while their back is often rough, with a texture in relief, to prevent them from slipping while held in a hand or from sliding on the table. Hwa-tu makes a satisfying snap sound when thrown down with vigor.
