				I saw two skyscrapers 2 either of which solve the puzzle.
 
 
I enjoyed this one -- good basics. |

				| X-wing:3 followed by xy-wing:247 also solves it |

				Another solution using digit 2 is a m-wing with ending pincers in r2c5 & r9c1.

				Easy-to-spot skyscraper on rows 2 and 8 knocked out the 2 in R3C6.
 
Go Saints. |

All the self congratulatory backslapping not withstanding, humbly I ask:
 
 
 	  | Code: |

| 27 8  1 | 9  237 4   | 236  5   36   |
 
| 4  27 3 | 6  27  5   | 9    8   1    |
 
| 6  5  9 | 8  123 12* | 234  7   34   |
 
+---------+------------+---------------+

| 5  37 8 | 2  4   179 | 1367 39  3679 |
 
| 1  6  2 | 3  8   79  | 5    49  479  |

DRAW/PLAY gives hint of '1' at r3c6.  What is the line of reasoning?

I don't know if it's DRAW/PLAY's reasoning, but there's a skyscraper on 2 in rows 2 and 8. |

				Ema,
 
     
 
       1-9 has to be in box 9 so R8C6 is 27.
 
 
      2- there is an x-wing on 3( rows 4 and 7) so 3 is out of R3C7 and R8C7 
 
   
 
  then R3C7 =24 and R8C7=47                                                     
 
        
 
       3- R8C6,R3C7 and R8C7 form an xy-wing(27,24 and  47) that 
 
                    
 
    eliminates 2 of R3c6 |

Bingo.
 
 
Thank you.  The steps and line of reasoning makes sense and is easy to follow.  (Sorry to have to admit to being unable to follow painting skyscrapers with triple x-man wings with a side order of pincer transports.)
