One Turn Kill

A One Turn Kill is achieved when a player wins a Duel in the space of a single turn, as soon as said player has the appropriate cards in their hand/Graveyard and has control over the duel.

In one turn, all of the opponent's Life Points, which is normally assumed to be no less than 8000, must be depleted, or an alternate victory condition must be fulfilled.

Significant or reliable OTKs generally consist of 4 or fewer cards, do not require the opponent to have particular cards or rely on indefinite chance, such as the effect of "Snipe Hunter".

Traditional and Advanced Formats will have very different OTK styles, owing to the allowable Card Pools. The Advanced Format banlist is updated every six months to reduce the viability of OTKs.

A One Turn Kill that is pulled off during the player's first turn is referred to as a First Turn Kill.

OTKs in Media
OTKs are rare in Yu-Gi-Oh! media, especially prior to Yu-Gi-Oh! ZEXAL, but are not non-existent. In many cases, an OTK in the anime is shown either to show off the strength of a powerful Duelist, or for the winner to have a come-from-behind victory. Since Duelists usually start with 4000 Life Points in the anime, an OTK is declared when all 4000 are depleted in one turn. Some Duelists have OTKed their opponents in the anime, including:
