Pop-up duels are a gameplay element from the Chocobo series. Playing much like a game of Rock-Paper-Scissors, the player will choose cards from his/her hand to combat the cards the opponent possesses. Each player has a Health Point (HP) gauge showing the player's remaining health, and a Crystal Points (CP) gauge showing which special attacks may be used. While the opponent's hand is never revealed, during the opponent's turn the color of the cards they hold is revealed.
