Duel winners are cards capable of automatically winning a Duel once certain unique conditions have been met. They are separate from Match winners, in that these cards only help to win a single Duel.
- All monsters that are Duel winners have been DARK Attribute, with the sole exception of "Horakhty" who is DIVINE Attribute.
- The majority of Duel winners were first seen in the anime or manga before being released in the OCG/TCG. The two that were not are both the only Spell Cards to be Duel winners.
