The weekend (Friday) USA Today puzzle is usually a challenge, although I believe it does not require advanced moves.

Their site, though, is a nightmare of ads and pop-ups and other garbage. Not recommended. (Stay away!)

This is today's puzzle. I have not done it. I have verified it has only one solution, and that it requires no advanced moves

Code:

is this a joke ?

solved entirely by "hidden singles"
    ( even after removing the superfluous clue at r3c1
    to give a symmetrical puzzle )

No,

Someone posted a question about this puzzle in another forum thread. Unfortunately, I lost that message while trying to move it.
