The hidden attraction in the park is the theme park of death, Death-T. This cost ¥10 billion to construct and was made for Kaiba to get revenge on Yugi.

Death-T 1 contains a shootout game, "Shooting Stardust".
Death-T 2 is comprised of three stages:
"Electric Chair Ride" ("Electric Chair Ride of Death" in the Japanese version): A ride designed to scare the passengers and electrocute them with a million volts if they scream. "Murderer's Mansion": a haunted house, with a large guillotine. Entrants must solve a riddle to avoid having their hand cut off.
A battle with the murderer Chopman in a chamber in the mansion.
Death-T 3 contains a room with falling blocks. The player must climb the blocks to the exit without getting crushed.
Death-T 4 contains a giant Capsule Monster Chess arena. An artificial Penalty Game is inflicted on the loser.
Death-T 5 consists of a game of Duel Monsters in the dome at the top. An artificial Penalty Game is inflicted on the loser.
