The episode received positive reviews from critics, who praised Samberg's performance, character development and writing although the subplots received a mixed response.

Amy (Melissa Fumero) learns that she has passed her Sergeant's Exam and will be officially promoted in a week. Jake (Andy Samberg) decides to work with her on their last case before she is a sergeant and chooses an investigation of a series of arsons connected with Amy's love for crosswords.

To Amy's delight, Jake brings in the victim, Amy's favorite puzzle author, Melvin Stermley (David Fumero). To Jake's dismay, however, “Vin” turns out to be hunky, personable, and the opposite of the nerd Jake envisioned. Vin and Amy begin bonding throughout the case, causing Jake to feel jealous. Jake comes to believe that Vin's friend Sam Jepsen is starting the fires, but Amy and Vin come to believe that a different person is starting the fires to spell their name. While pursuing a suspect due to Vin's hunch, Jake doesn't follow protocol and monitors Jepsen. However, Jepsen turns out to be innocent and the real arsonist starts a fire where Jake was supposed to guard, angering Amy. After Jake apologizes for his behavior, he solves the case by finding that it was Vin's obsessed neighbor who caused the fires as part of an elaborate marriage proposal and death threat for Vin.

Meanwhile, Holt (Andre Braugher) and Gina (Chelsea Peretti) meet the competition for the Police Commissioner position. At the meeting, Holt is intimidated by Captain Olivia Crawford (Allison Tolman) who is in the running for the position and is opposed to precincts. He considers allying with one of the selectors, Patrick, only for Patrick to claim that Crawford was nominated as a public relations ploy and that the NYPD should not have a female Commissioner. Holt reveals this to the audience, causing a new group to be selected to nominate the Commissioner. As a result, Holt and Crawford depart from the incident as "frenemies."

At the same time, Terry (Terry Crews), Rosa (Stephanie Beatriz), Hitchcock (Dirk Blocker), and Scully (Joel McKinnon Miller) debate over who should get the new Detective car. Terry tries to solve the issue by having them draw names from the basket, but the other three accuse him of cheating after he draws his own name. Eventually, Terry breaks down and confesses. Rosa decides to give it to Terry as she feels that he is willing to help his colleagues whenever in need. She tricks Hitchcock and Scully into agreeing by washing their car and claiming that it is a new model.

"The Puzzle Master" received positive reviews from critics. Genevieve Valentine of The A.V. Club gave the episode a "B+" grade and wrote, "When a series reaches a certain age, it gets a sense of narrative moving in both directions. There's the history the show has made, and the pull of the future on the shape of the story. Brooklyn Nine-Nine is old enough to have built a world to draw on, but ambitious enough to recognize the need for change. In the past, most of the forward motion has been conveniently sidestepped in order to keep the team together. But whatever happens from here, with Amy on the cusp of becoming a sergeant and Captain Holt hoping to be the next Commissioner, 'The Puzzle Master' feels like it's very deliberately looking ahead."^[3]
