Yu-Gi-Oh! Trading Card Game.

Yu-Gi-Oh! Official Card Game is the version of the Yu-Gi-Oh! card game manufactured by Konami. It is played mainly in Japan and parts of Asia. The OCG used to be printed exclusively in Japanese (JP), Korean (KR). It has previously been printed in English (referred to as Asian-English); despite being part of the OCG, Asian-English cards have "Yu-Gi-Oh! Trading Card Game" printed on their backings, though with a different logo. In the past there have been 3 different Chinese prints of cards, including two "Blue-Eyes White Dragon"s and one "Dark Magician", though they were only for promotional purposes. Starting from Duel Starter Deck and onward, the OCG has started to be officially printed and distributed in Traditional Chinese (TC), and will now follow a regular release schedule.^[1]; additionally, starting from The Duelist Advent, Japanese cards distributed outside Japan are considered "Japanese-Asian" (JA).

Despite being part of the OCG, Korean cards use the TCG layout and artworks. Traditional Chinese cards use the same layout and artworks as the Japanese ones.

TCG cards are not legal in OCG tournaments. Due to Japanese, Asian-English and Korean cards having different backings, if a player chooses to use a mixture, they must use protective sleeves that cover the back of the cards.^[2]

OCG tournaments are divided into three classes: Expert, which has no age restriction, Regular: for secondary school students and Challenge, for primary school students.
