1) “Lego Masters,” 8 p.m., Fox. We’re down to the final four duos in this fun competition. There are brothers … and a brother-sister … and two wedding DJ’s … and two school guys, a coach and a band director. Inan impressive hour, they make Lego creations (shown here) that can nudge a ball across a table. That leads into next week’s finale … and, for four Mondays after that, a junior edition.
2) “Survival Mode,” 10 p.m., NBC. This episode that was originally set for the series-opener (July 7), then delayed: In 2022, Florida was lashed by Hurricane Ian, its deadliest storm in 87 years. In that state alone, Ian killed 149 people and caused $110 billion damage. This focuses on three sets of people who tried to ride it out, instead of evacuating.
3) “FBI” and “FBI: Most Wanted,” 9 and 10 p.m., CBS. The first rerun involves a young girl who was kidnapped and then used in a major heist. The second is the search for someone who stabbed two sorority sisters.

At 9 p.m., “Jaws vs. Mega Croc” uses computers to create a fight between a great-white and a Nile crocodile. At 10, “Shark Storm” has accounts of last year’s Gulf Coast attacks.
5) “Celebrity Family Feud,” 10 p.m., ABC. New episodes began Thursday, getting off to a strong start in the ratings. Meanwhile, reruns are on Mondays. This one has actress Taraji Henson and singer-actress Jennifer Hudson. Then it’s people from the Dan Patrick and Rich Eisen radio shows.
