any help would be appreciated..

I see a hidden pair. After that a naked triple or two will finish it off.

Code: Select all

482.3.......2..35.35...1..494.3.........96..3.35....9..7.9.2.3..93...64.....83...

Please humor a newbie? I found the hidden pair right off, but after staring for 45 minutes cannot find a naked triple that will eliminate any options. Your help in moving me along would be most appreciated.

Naked Triple on 467 in column 5 rows 237.

Thank you. Yes, I saw that triple. It allows me to eliminate the 7 in c5r8 (itself part of a naked triple) but I don't see how that gets me any further.

Those moves, plus some locked candidates and singles, will expose another triple in column 4, and then it is singles to the end.

5 moves, including a trio: Show

• r5 "hidden" duo {4,5}
  
  
• b8 "hidden" duo {4,6}
  --> c5 "hidden" trio {1,2,5}
  --> (7) c5\b2

combine the above
--> c4 "hidden" duo {1,7}
--> c4 8
