?Jeopardy? winner back for more

NEWYORK—‘‘Jeopardy!’’ master Ken Jennings returns to try to extend his winning streak in a new episode that airs today.

The 30-year-old Salt Lake City software engineer became an unlikely TV star this summer when he began mowing down opponents on the quiz show. He won 38 straight games, for a total of $1,321,660, before the show went on hiatus in July.

‘‘Jeopardy!’’ used to limit its champions to five appearances before changing its rules a year ago, allowing a winner to keep competing until being beaten.

‘‘Jeopardy!’’ will hold two more weeks of original episodes, which began taping in August, before leaving on another hiatus for a special tournament.

If Jennings keeps winning, he’ll keep coming back. Game spokesman Jeff Ritter said there’s been no discussion of a cutoff point or another change in the rules.
