the 234 wing? in r5c7, r6c8, r9c7 gives -3 in r4c79
I solved this one with only basic eliminations, which makes me think I must have made a lucky mistake early on. I might retry it.
Yes, I must have ...

No, that's not right! I solved it with basics.

Oh, I see what you're missing.

Ah, so simple! Thanks, it was driving me crazy.

The fives in row 7 must be in box 9.

That'll help you get going again.

Thanks, I must be asle ...

I'm probably dozing, but how can I solve this puzzle from here without using advanced techniques? There's an obvious X-wing that will solve the puzzle, but we're supposed to be able to solve hard puzz ...

Using Firefox under Linux, I'm seeing no puzzle on the main page, and the archives stop at September 29. Is the Sudoku engine down, or has something broken compatibility with my browser?
