I am stuck on this puzzle: http://pairofdocs.net/wp-content/uploads/2023/05/PuzzleMix_ToroidalSudoku319.jpg. I do not see anything obvious and have not found any hidden pairs or hidden triples. I entered this into the PuzzleMix website and it indicates no errors. Please suggest that which I should try next.

From the initial puzzle these are the first steps:

Code: Select all: [1,1] r4c4=2 Hidden Single in row 4. <== I forgot this 2 from your initial puzzle to copy [2,1] Naked Triplet (146)c2r678 => (-14)r4c2 [3,1] Pointing, Claiming | (5)J2,c2 => (-5)r4c2 | (1)J3,c4 => (-1)r5c4 | (4)c4,J3 => (-4)r1c3 | (4)J8,c5 => (-4)r9c5 | (7)J6,c7 => (-7)r5c7 | (9)J7,c8 => (-9)r3c8 (-9)r4c8 (-9)r5c8 | (6)c9,J7 => (-6)r2c8 (-6)r9c8 [4,1] Pointing, Claiming | (6)c8,J9 => (-6)r7c6

The Jigsaw-pieces have the following numbering:

Code: Select all: 123345671 223445871 233455891 234458896 734558996 714588966 712589967 112389667 122349677

But then you are not yet finished.
A skyscraper is dooming at the horizon....

Code for SiSeSuSo: Show

I think this is not the original puzzle. Can you post the original?
