I probably made this harder than it should be and eventually had to do it with a chain.

Code:
+--------------+---------------+--------------+
| 9   1   2    | 5678 4   58   | 67  68    3  |
| 6   5   8    | 79   3   17   | e279 d12  4  |
| 4   3   7    | 689  b16  2   | 69  c168  5  |
+--------------+---------------+--------------+
| 127 6   4    | 3    9   17   | 8    5   27  |
| 27  9   3    | 58   27  58   | 1    4   6   |
| 127 8   5    | 4    127 6    | 3    9   27  |
+--------------+---------------+--------------+
| 5   4   1    | 267  a67  9   | f26  3    8  |
| 3   7   9    | h26  8    4   | 5   g26   1  |
| 8   2   6    | 1    5    3   | 4    7    9  |
+--------------+---------------+--------------+



If you plug 6 into r7c5 in the chain below another 6 arrives in the same box in r8c4 so r7c5<> 6

(6)r7c5-(6=1)r3c5-r3c8=(1-2)r2c8=r2c7-(2=6)r7c7-r8c8=(6)r8c4

Hi Clement - nice one. Don’t you mean -6r8c4,r7c7 ?

My chain was similar to the others. 6r7c7 = r8c8 - (6=8)r1c8 - (68=1)r3c8 - (1=6)r3c5 => r7c5 <> 6; stte.

There's a nice UR Type 1 on 58 in r15c46 which means r1c4<>5,8. A good rinse reveals either a Skyscraper on 6 or a Finned X-wing on 6, which can take you to the end. But that is more steps than many of you needed.

cheers...immp
