Yu-Gi-Oh! is a popular Japanese anime and manga franchise from Kazuki Takahashi that mainly involves characters who play a card game called Duel Monsters (originally called Magic & Wizards in the manga. See the section "Card game" below for different names of the game) wherein each player purchases and assembles a Deck of Monster, Spell, and Trap Cards in order to defeat one another and gain victory.
It began as a manga in Japan in 1996, the Yu-Gi-Oh! franchise has since grown to an immensely successful global brand, spawning various manga and anime series, a real-life version of the card game featured in the story, video games, toys, and many other products.
