.4.3.528......7.9......6.1.873129564951764328.6.538179..685..41...67..52..594..3.

One possible cause is that not all relevant moves are set in the Solver. Go to Edit / Preferences ... / Solver Tab and make sure that as many moves as possible are checked.

The finish was not that easy and involved a Type 4 UR, Sue de Coq, XY Chain and XY Wing. If not all these are set a solution may not be possible. Play it safe and just check everything.

I think a puzzle of this degree of difficulty should be solved by app, not by hands. Though this puzzle's chain is very short.

Who would enjoy that? The app?

not by hands.

I agree. A brain is a better solving tool.

Btw, here's my manually cerebrally found solution:

Code: Select all
.---------------------.------------.---------------.
| ae1(6)   4     79   | 3   19  5  | 2    8    7-6 |
|   12356  1238  28   | 24  18  7  | 46   9    35  |
|   235    2389  2789 | 24  89  6  | 47   1    35  |
:---------------------+------------+---------------:
|   8      7     3    | 1   2   9  | 5    6    4   |
|   9      5     1    | 7   6   4  | 3    2    8   |
|  d24     6     24   | 5   3   8  | 1    7    9   |
:---------------------+------------+---------------:

| bc127    128   5    | 9   4  c12 | 678  3  a(6)7 |
'---------------------'------------'---------------'

(6=17)r1c1,r9c9 - (1|7)r9c1 = (2,1)r9c16 - (2|1=43)r6c1,r8c6 - (4|3=16)r81c1 => -6 r1c9; stte

Step 2: (5)r3c1 = (56-4)r2c17 = (42)r3c74 => -2 r3c1
