The KC DuelTek 760 is a Dueling computer created by KaibaCorp, located at the same site that the Grand Championship takes place. It features varying Decks with five different levels of difficulty.
Zigfried von Schroeder hacked into KaibaCorp's systems and raised the machine's difficulty level to its maximum, before connecting its Life Points to the location's doors, thus locking them until the computer could be defeated. Yugi Muto chose to Duel the computer using Rick's Deck.
The computer relied on a beatdown strategy with monsters like "Berserk Gorilla" and "Airknight Parshath", while depleting Yugi's hand with "Robbin' Goblin". Yugi countered its strategy using "Heart of the Underdog" a card he had given to Rick and "Spirit Ryu" which gained ATK dependent on the number of Dragons discarded to the Graveyard in the turn it was Summoned. In the end Yugi defeated the DuelTek and freed his friends.
