TV viewers now have an answer to a frequent question: When will “The Masked Singer” (shown here) return?
They also have the answer to a rarely asked question: When will there be a show about people toppling dominos?
Both will be March 9, as part of the Fox network’s spring makeover. That also puts the two “9-1-1” shows back together, returns some reality shows (“MasterChef Junior” and “Name That Tune”) and debuts a clever, offbeat comedy after “Call Me Kat.”
To make room, several shows will wrap up. They include “Next Level Chef” on March 2, “I Can See Your Voice” on March 8, “Joe Millionaire” and “Pivoting” on March 10 and “The Cleaning Lady” on March 14.
In general, Fox avoids reruns by using wrestling, sports and, at times, lower-budget reality shows. Its cartoons, however, currently have reruns or are being bumped by Sunday specials; they’ll be back to new episodes on Feb. 27, two weeks after the Super Bowl. The changes:
— March 9: “The Masked Singer” launches a new season at 8 p.m., with “Domino Masters” at 9. The latter has Eric Stonestreet (“Modern Family”) hosting, sportscaster Joe Buck announcing and Danica McKellar (the actress, from the original “Wonder Years,” and math whiz) as one of the judges.
–March 17: “MasterChef Junior,” with kids ages 8-13, starts its eighth year at 8 p.m. “Call Me Kat” stays at 9, but now it’s followed by “Welcome to Flatch,” a droll show (based on a British comedy) that pretends to be a documentary about small-town youths.
— March 21: “9-1-1,” which is on a mid-season break, returns at 8 p.m. It will be paired with its spin-off, “9-1-1: Lone Star,” which moves to 9.
— March 29: “Name That Tune” starts its season, with Jane Krakowski hosting and Randy Jackson as band leader. It’s at 9 p.m., with “The Resident” continuing at 8.
