In episode 81, Bob Banter uses this card during his duel against Jaden Yuki. He sets this card in Defense Position via the effect of "Quiz Panel - Slifer 10". Later "Elemental Hero Burstinatrix" attacks and destroys this card. Jaden was then asked how many turns have passed since the start of the Duel. Jaden correctly answered the question prompted by this card's effect by guessing 5 turns have passed since the start of the duel, but Bob activates "Question Change" to avoid taking damage and flip "Quiz Panel - Obelisk 20", which activates its Flip Effect. This card's effect then sets "Quiz Panel - Slifer 30" in Defense Position. Jaden is then asked what are the combined Levels of the total monsters that are in the Graveyard. Jaden guesses three, but Bob reveals that he is wrong as the question asked the combined Levels of the total monsters that were currently in both players' Graveyards. Because of this, "Burstinatrix" is destroyed and Jaden takes 800 damage. After that resolves, "Quiz Panel - Obelisk 20" is destroyed and "Quiz Panel - Obelisk 30" is set in Defense Position. After Bob Special Summons "Quizzer Panel 9", he activates the latter's effect to return all Quiz Panels from his Graveyard to his Deck.
