ok, let me see if I can duplicate Danny's path
x-wing 5
xy-wing {2,5,6} removes 6 from r8c6
xy-wing {2,5,6} removes 6 from r2c9
finned x-wing 5 removes 5 from r5c8

A three step sequence:
x-wing 5,
finned x-wing 5 deletes 5 in r5c8,
xy-wing 256 with pivot 56 inr3c8 and pincers in r1c7 & r5c8

Ted,
Danny's solver/generator comes up with a solution path to these puzzles. he isn't posting that anywhere that I know of. but I think its fun sometimes to try and pinpoint the path that was found when the puzzle was generated. |

Ted & Norm:
My solver produces a solution path that I manually edit to see what can be trimmed/reordered. I also use HoDoKu to look for alternate endings for puzzles where my solver has chosen an XY-Chain.
I've recently gone back and added my edited solution to the head post of puzzles a week or more old. This is a FYI for those who may be curious.
Norm is in the ballpark! And Ted hit the home run!!!
Regards, Danny
BTW: I appreciate the positive feedback on my puzzles  |
