NBC’s “Identity” was no secret to American auds Monday night, as the net’s latest gameshow opened to good ratings results.

Skein, in which contestants try to match strangers with various descriptions based solely on their appearance, retained all of its young-adult lead-in from the net’s hit gamer “Deal or No Deal” and led its mostly repeat broadcast competish in the 9 o’clock hour.

According to Nielsen nationals, “Identity” averaged a 4.4 rating/11 share in adults 18-49 and 12.27 million viewers overall, following “Deal” (4.4/12, 15.37m). “Identity” seemed to click especially with younger men, as it built by 2 share points on its “Deal” lead-in (3.5/10 to 2.6/8).

Penn Jillette-hosted series will be stripped at 8 o’clock for the rest of this week. NBC employed a similar sked strategy last year at this time with “Deal or No Deal.”

If successful, “Identity” could be brought back at midseason as a regular series. Following its weeklong premiere last December, “Deal” relaunched two months later as a series and quickly became a key asset for the Peacock.

Among the handful of other firstrun broadcast programming Monday was another weak performance for ABC drama “What About Brian” at 10 o’clock (2.0/5 in 18-49, 4.58m).

ESPN’s “Monday Night Football” game between Indianapolis and Cincinnati (5.6/15 in 18-49, 14.22m) was the night’s No. 1 program in most key demos.
