Two steps.
| Quote: | Two perspectives of the same UR 36 in 23c68:
Looking in row2, no outside digits 3 or 6 exist,
Looking in row 3, only the 6 in r3c3,
Thus r3c3 must be 6 to prevent the deadly pattern.
or
x-wing on 3 overlay on the UR deletes 6 in r3c68 thereby forcing r3c3=6.
An ER on 5 with hinge in box 4 and strong link in r36c6 completes the puzzle.

I'm sure I had unnecessary moves because there was a quad or quint which went unseen for quite a while.
M-Wing (59)
Kite (9)
ER (4)
Type 4 UR (36)
Coloring (5) |

First thing I spotted was X-wing on 4. Then I had to do something with those 59 doubles all over the grid, so I ran two chains. That left me with XYZ-wing 145, XY-wing 159 and finally XYZ-wing 145 for the win. Phew!
Hope all of you are enjoying wonderful spring weather like we are here in Pennsylvania! |
