The Duel Masters Trading Card Game is a two-player and 3 vs. 3 team collectible card game (CCG) jointly developed by Wizards of the Coast, Shogakukan, and Mitsui & Co., Ltd.. The card game is part of the Duel Masters franchise.

It was released in Japan in May of 2002, where it quickly became the number one selling trading card game for over a year.[citation needed] Due to this popularity, it was released in the United States on March 5, 2004, where it has also done well.[citation needed] The game shares several similarities with Magic: The Gathering, the world's first collectible card game which was first published by Wizards in 1993. In fact, Duelmaster was originally intended as an alternative tradename for Magic: The Gathering and that the earlier game play was abandoned in the Duel Masters manga plot to promote this latest experience.

As in Magic: The Gathering, Duel Masters players summon creatures and cast spells using mana. Key differences include the fact that all creatures and spells can act as mana producers, creatures cannot block attacking creatures without having the "blocker" ability, and that creatures only have one "power" statistic. Furthermore, duelists have shields in the form of cards that go to their hand when "broken" as opposed to Magic's "life points". Whether this will be the norm remains to be seen, as Wizards of the Coast may add new rules and card types to increase the game's longevity. Due to its popularity , it has successfully launched four video games (three in GBA and the other in PS2), titled DuelMasters Kaijudo Showdown, DuelMasters Sempai Legends, DuelMasters Shadow of the Code for the GBA and DuelMasters PS2.
