Pinochle's Resolve (ピノクルの思結 Pinokuru no Kakugo) is the seventeenth episode of Phi Brain: Kami no Puzzle Season Two and the fourty-second episode of the anime series overall.
Pinochle challenges Kaito to a puzzle, saying he will tell him everything about what happened between him and Freecell should he win. However, the loser will fall into a furnace. As Pinochle tells of how Kaito was supposedly a liar, Kaito simply states he wants to know the truth so he can properly apologise for what he may have done and soon makes a comeback. As they reach the top, Kaito refuses to finish Pinochle off, as hurting someone for the sake of a friend is not something that friend would appreciate. As Whist sabotages the puzzle to try to make Pinochle fall, Kaito manages to use his smarts to rescue him. As Pinochle realises what he wants is to become true friends with Freecell, his Orpheus Ring breaks, revealed to be another Replica Ring. As Freecell and Whist tell the others that Pinochle died, Pinochle reveals that he spread bad rumors so that Freecell wouldn't become friends with Kaito and abanadon him, with Cubic deducing that the Ring caused him to believe in his own memory that Kaito did it. As Pinochle mentions he doesn't know the connection between Kaito's promise and the death of Freecell's mother, Kaito decides to become friends with him.
