The '''''Yu-Gi-Oh! Official Card Game''''' is the version of the ''Yu-Gi-Oh!'' card game for Eastern Asia. The equivalent game outside of Asia is the ''[[Yu-Gi-Oh! Trading Card Game]]'' (''TCG'').

It was first released in February 1999, with the release of ''[[Vol.1]]'' in Japan.

''OCG'' products are advertised as suitable for 9-years-old children or older (in contrast to the ''TCG''{{'}}s 6+, and it used to be 12+ until 2015), and tournaments are divided into three age brackets: Expert, which has no age restriction, Regular, for high school students, and Challenge, for junior high school students.

==Regions and languages==
The ''OCG'' is played mainly in [[Japan]] and [[Korea|South Korea]], but also in [[China]], [[Hong Kong]], [[Indonesia]], [[Malaysia]], [[Philippines]], [[Singapore]], [[Taiwan]], and [[Thailand]]. It was printed exclusively in [[Japanese]] and [[Korean]] for most of its history, but is also currently printed in English (referred to as [[Asian-English]]) and [[Simplified Chinese]], and has been previously printed in [[Traditional Chinese]] for a brief period.<ref>{{Cite web|url=http://ygorganization.com/are-you-ready-for-more-yu-gi-oh-languages|title=Are You Ready for More Yu-Gi-Oh Languages?|website=YGOrganization|author=Eva|date=December 12, 2013}}</ref>

Japanese cards used to be distributed in all ''OCG'' territories, though this has since ceased and are now only sold in Japan, by Konami of Japan. These Japanese cards distributed outside Japan were referred to as "[[Japanese-Asian]]" prints. Asian-English, Japanese-Asian, and Traditional Chinese cards are distributed by Konami of Hong Kong. Korean and Simplified Chinese cards are distributed by [[wikipedia:Daewon Media|Daewon Media]] and Shanghai Windo Entertainment Co. Ltd respectively.

Even though they are part of the ''OCG'', Korean cards (as well as Asian-English ones before 2023) use the [[edited artwork]]s made for the ''TCG''. 

===Card backing===
Unlike ''TCG'' cards, which all use the same logo, different regions of ''OCG'' cards have different logos on their [[card backing]]s.
* Japanese and Japanese-Asian card backs have a logo containing the Japanese ''Yu-Gi-Oh!'' logo (with English Ruby text) and the text ''Official Card Game Duel Monsters'' in katakana.
* Korean card backs have a Korean ''Yu-Gi-Oh!'' logo (with English Ruby text) and the text ''Official Card Game'' in English.
* Asian-English card backs have a Japanese ''Yu-Gi-Oh!'' logo (with English Ruby text) and the text ''Trading Card Game'' in English (despite being part of the ''OCG'' and not the ''TCG'').

==Card legality==
''TCG'' cards are not legal in ''OCG'' tournaments. Due to Japanese, Asian-English, and Korean cards having different [[Card backing|backings]], if a player chooses to use a mix, they must use sleeves with an opaque reverse side to cover the backings.

Since [[September 2013 Lists (disambiguation)|September 2013]], the ''OCG'' and ''TCG'' have had different [[banlist]]s, with multiple cards being [[Forbidden]] in one list but [[Unlimited]] in the other (in both directions).

==Rule revisions==
===Official Rules===
'''Official Rules''' (公式ルール ''Kōshiki Rūru'') were introduced with ''[[Vol.1]]'' and were adjusted with the release of ''[[Starter Box: Theatrical Release]]'' and ''[[Vol.7]]''.

Differences from later formats are:
