From Viz:
Sitting by himself in the back of the class, 10th-grader Yugi always had his head in some game--until he solved the Millennium Puzzle, an Egyptian artifact containing a powerful spirit from the age of the pharaohs. Awakened after three thousand years, the King of Games possesses Yugi, recklessly challenging bullies and evildoers to the Shadow Games, where the stakes are high and even the most ordinary bet may result in weirdness and danger beyond belief. Let the games begin.

Note: Viz published Vol 1-7 as Yu-Gi-Oh!, Vol 8-31 as Yu-Gi-Oh!: Duelist and Vol 32-38 as Yu-Gi-Oh!: Millennium World with reset volume counts. The Viz Omnibus covers the whole series across 13 volumes without these demarcations.
