Yu-Gi-Oh! (Game King or King Of Games) is a Japanese manga created by Kazuki Takahashi. It has spawned a franchise that includes multiple anime shows, a trading-card game, and numerous video games. Most of the incarnations of the franchise involve the fictional trading-card game called 'Duel Monsters' (originally known as 'Magic & Wizards'), where each player uses cards to duel each other in a mock battle of fantasy monsters. The Yu-Gi-Oh! Trading Card Game is the real world counterpart to this fictional game on which it is loosely based.
