Yu-Gi-Oh! Ultimate Masters: World Championship 2006: Game Glitches
- Using "Power Bond" to summon "UFOroid Fighter" does not result in taking any damage at end of turn, presumably because "UFOroid Fighter"'s ATK is listed as '?' rather than a number.
- If your "D.D. Survivor" is removed from play while control is switched, it is Special Summoned back to the opponent's field instead of your own.
- You can't clear the game (the last booster is unattainable) because the "Huge Revolution" challenge in the Theme Duel menu has a glitch - even if you win the Duel after successfully activating that card, the game will register as you did not successfully activate it.
- "Legendary Jujitsu Master"'s effect activates while it's in Attack Position.
- "Grave Ohja" can be attacked when there is a face-down Defense Position monster if "Staunch Defender" has been activated.
- When you activate "Dragged Down into the Grave", if the card your opponent chooses is a Dark World monster, it is treated as having been discarded by your opponent. Due to this, the second effects of monsters like "Goldd, Wu-Lord of Dark World" will activate.
- "Magic Cylinder" is unaffected by "Royal Decree".
- "Shadow Ghoul" is mistakenly categorized as a Nomi monster in your Card Pool, presumably because of its counterpart, Wall Shadow.
- When you activate "Elemental Hero Erikshieler's" effect while there is a Fusion Monster removed from play, all the Fusion Monsters removed from play are sent to your Main Deck instead of your Extra Deck.
- You can discard Spell Cards or Trap Cards to destroy 0 ATK monster with the effect of Armed Dragon LV7
- Level 6 monsters cannot be destroyed by "Roulette Barrel"'s effect.
- In the Theme Duel "Token", you can achieve it having Summoned only 10 Tokens.
