Instructions
Play the game as normal until you have defeated your opponent in battle. After the victory screen is shown, press the "X" button to bring up the "Graveyard Slots" mini-game.
Press the "Square" button to stop the leftmost spinning slot, the "Triangle" button to stop the middle slot and the "Circle" button to stop the rightmost slot. The goal is to stop the three slots so that all three cards match.
Line up three cards showing either "Curse of dragon" (which looks like a flying bone dragon) or "Black Pendant" (which look like a pendant on a blue background) after defeating Yu-Gi-Oh.
Line up three cards showing either "Dark Prisoner" (which looks like a chained green monster), "Togex" (green monster with purple spikes) or "Fairy Meteor Crush" (grey meteor on a reddish background) after defeating Tristan.
Line up three cards showing "High Tide Gyojin" (green amphibious monster) after defeating Mako or "Larva Moth" (spiky green insect) after defeating Weevil.
