Sup, Norm.

Another lonely unsolved puzzle, so...

...is this the hintular m-ring?

At the SSTS position:
Code:
  *--------------------------------------------------------------------*
 | 13     5      2      | 4      9      7      | 8      13     6      |
 | 4      136    67     | 13     135    8      | 357    9      2      |
 | 137    9      8      | 6      135    2      | 3457   1347   135    |
 |----------------------+----------------------+----------------------|
 | 8      4      1      | 9      23     5      | 6      23     7      |
 | 6      2      9      | 13     7      134    | 345    8      35     |
 | 5      7      3      | 8      24     6      | 1      24     9      |
 |----------------------+----------------------+----------------------|
 |*137    136    5      | 2      13468  1349   | 39    *1367   138    |
 | 2      8     *67     | 5     -613    139    | 379   *1367   4      |
 | 9      136    4      | 7      1368   13     | 2      5      138    |
 *--------------------------------------------------------------------*

(7=6)r8c3-(6)r8c8=(6-7)r7c8=(7)r7c1-loop =>r8c5<>6 (among the elims), STTE.

yes, that would be it.

I probably should have been more specific that the m-ring comes after a few coloring steps like simple sudoku would have found.
the M-ring would be available and deals a death blow to this puzzle at the SSTS grid.

just in case you are wondering the first three SSTS steps are
skyscraper
kite
and a x-chain
which will make available the m-ring.

The m-wing is commonly seen in this forum, but not so much the m-ring. Too bad, because as a loop, it's potentially more powerful than the m-wing.

For some nice examples, there's this thread over yonder.
