Well that's a resounding lack of interest.

There is a solution [not mine] in 5 main steps.
I started well, paying attention to box 7 [weak spot in the puzzle].
However I missed that (5 step) solution because it needs an initial elimination that I discarded
as unimportant (being crucial for the following main step). There is an easy first digit to
get but it does not help anything. I found many useless eliminations and unfortunately
gave up too early. Some players may have had a similar experience.

i did not post my solution because i found it too complex:
basics:
Hidden Text: Show
Code: Select all
( n3r9c9   n4r7c7   n6r8c2   n6r1c4   n8r7c8   n8r1c2   n9r4c9
  n4r8c1 )

intersections:
((((7 0) (1 9 3) (1 2 7)) ((7 0) (2 9 3) (1 2 7)))
 (((2 0) (9 1 7) (1 2)) ((2 0) (9 3 7) (2 5))))

PAIR BOX: ((7 9 9) (1 2)) ((8 8 9) (1 2)) 
(((9 8 9) (1 6 7)))

Code: Select all
127r1c1 => r456c5 <> 5
 r1c1=1 - b7n1{r9c1 r7c2} - c9n1{r7 r2} - r3n1{c8 c6} - b2n5{r3c6 r1c5}
 r1c1=2 - r9c1{n2 n1} - r7c2{n1 n5} - c4n5{r7 r456}
 r1c1=7 - r6c1{n7 n9} - r5c3{n9 n5} - b7n5{r9c3 r7c2} - c4n5{r7 r46}
 
r5c5{n9 n1} - c4n1{r5 r78} - r9n1{c6 c1} - r1n1{c1 c9} - r1n7{c9 c1} - r6c1{n7 n9} => r5c3 r6c5 <> 9

4r36c3 => r3c8 <> 1,4
 r3c3=4 - r3n9{c3 c1} - b1n2{r3c1 r1c13} - r1c7{n2 n5} - r3n5{c8 c6} - r3n2{c6 c8}
 r6c3=4 - r4n4{c2 c5} - c5n8{r5 r9} - c5n5{r9 r1} - r3n5{c6 c8}
 
ste.

Thank you for your persistence! N2H was supposed to mean Not Too Hard, but maybe that one was a bit inhuman.
I better withdraw my slightly sarcasmic comment.
