Wacky reality TV shows that are here or coming soon

Networks haven’t seen a new breakout reality hit in years.

Still, they try. A few prospects:

“Love Island”: CBS has optioned rights to this series, a smash hit in the U.K., which traps a bunch of hard-bodied contestants on a tropical island and follows them on dates and challenges as viewers help determine their actions and choose the winners. It may surface as early as next spring.

“Castaways”: ABC’s newest series tests “the human need for companionship under extreme circumstances.” It’s like “Survivor,” except 12 contestants are dropped off one by one in Indonesia and don’t know who else is playing or when they will be “rescued.” Their at-home lives are documented before the journey. (Now airing, Tuesdays, 10 p.m.)

“The Masked Singer”: Fox’s oddball show disguises celebrities (including Super Bowl winners, as well as Emmy and Grammy award nominees) in elaborate costumes. After they sing, a panel of judges asks questions to help identify them, in the style of “To Tell the Truth,” and those who remain anonymous advance until a winner is named. The series is expected in January.

“Million Dollar Mile”: CBS series aims to “shut down the streets of a major city” next season as players vie for $1 million while fending off “elite athletes” who try to stop them.

“Family Food Fight”: ABC series pits entire families against each other to cook everyday family recipes rather than Michelinstarred restaurant meals. They battle for a $100,000 prize. The show is expected in 2019.
