Yu-Gi-Oh! (Japanese: 遊☆戯☆王, Hepburn: Yū-Gi-Ō!, lit. 'Game King') is a Japanese manga series written and illustrated by Kazuki Takahashi. It was serialized in Shueisha's Weekly Shōnen Jump magazine between September 1996 and March 2004. The plot follows the story of a boy named Yugi Mutou, who solves the ancient Millennium Puzzle. Yugi awakens a gambling alter-ego or spirit within his body that solves his conflicts using various games.

The manga series has spawned a media franchise that includes multiple spin-off manga and anime series, a trading card game, and numerous video games. Most of these incarnations involve the fictional trading card game known as Duel Monsters (originally known as Magic & Wizards), where each player uses cards to "duel" each other in a mock battle of fantasy "monsters", forming the basis for the real life Yu-Gi-Oh! Trading Card Game tie in.
