[1] According to Nielsen Media Research, the episode was seen by an estimated 1.84 million household viewers and gained a 0.4 ratings share among adults aged 18–49.
Club gave the episode a "C+" rating, writing, "Forgettable from snout to anus, 'The Game of Boyles' is more dull than actively bad.
"[4] Brian Tallerico of Vulture gave the episode a 2 star rating out of 5 and wrote, "The worst episode so far of the final season of Brooklyn Nine-Nine, 'Game of Boyles' centers the extremely unusual extended Boyle family, a joke that worked best when it had Chelsea Peretti's withering glare to counter its extreme affability, and hasn't really since she left.
It feels more like a script that didn't make it through the writers' room in a previous season, pulled out of the bottom drawer and dusted off for this one.
