I cannot tell you whether you should watch “Love Island.”

That is a decision TV viewers must make for themselves , weighing the many hours they will lose against the colorful new vocabulary they will gain (no one wants to get “pied,” even if they’re a “melt”). In Britain, at least, millions of viewers have already given in to the temptation of the bizarre reality dating show, which is currently airing its fifth season . (All five seasons are available on Hulu.)

Now, CBS is betting that audiences in the United States will do the same: Beginning Tuesday, episodes of an American “Love Island” will air every weeknight until the August 7 finale, offering viewers the salacious highlights of the couples’ dalliances in a tropical villa .

Unlike the American dating shows that promise a path to the altar, there is a lot of partner swapping on “Love Island.” The group of singles spends the summer paired together as couples, and the show manipulates this simple formula to produce genuinely startling twists and turns : New contestants are brought in, the public votes to send uncoupled contestants on dates, people break up and then have to continue living in the same house.

The British version is hosted by Caroline Flack, but the tone is set by its snarky voice-over narrator , the comedian Iain Stirling, who mocks the contestants, the show and himself. For the U.S. series, the comedian and Vine star Arielle Vandenberg will serve as host, and the narrator has not been announced.
