Diamond -- Korean "hwa-tu" Flower Cards
48 cards, plus 1 additional December Junk, and 5 jokers and/or advertising cards

Flower cards were invented in Japan, possibly in order to circumvent anti-gambling laws against playing with conventional 4-suited card decks. Nowadays, however, games with flower cards are most popular in South Korea. Flower cards are much smaller in size than conventional cards (less than half size of standard poker cards) and also much thicker (as thick as credit cards). Japanese flower cards are called "hanafuda". Korean flower cards are slightly different and in Korean they are called "hwa-tu". The most popular Korean game is Go-Stop (in Japan the game is called Koi-Koi). The game Go-Stop is featured in the popular Korean film Tazza, which literally means "card shark" although the movie title was translated in English as The War of Flowers, or sometimes The High Rollers.

Flower cards are divided into 12 groups, each group representing one of the 12 months of a calendar year. Each month consists of 4 cards, however, the 4 cards of each month do not consist of cards of the same value, so any one of the 12 months could consist of 1, 2, or 3 "junk" cards, up to 1 "banner" card (with the possibility of 3 different kinds of banners, also called "ribbons"), up to one "object" card (also called "animal" cards although some of them feature non-living objects), and up to one "light" card (easily recognizable by the Chinese character "kwang" which means "light" or "bright").

The cards are listed here starting from January on top, down to December. Some decks include jokers and an additional December "junk" card - however, jokers are usually not used and only one of the December "junk" cards is used in play depending on which scoring system is used. It should also be noted that compared to a Japanese hanafuda deck, the Korean cards have the last two months (November and December) flipped.
