| OK. Here's what I think. There is an xy wing using cells r8c8,r5c8 and r9c9 with r8c8 being the xy. this eliminates 3 from r4c9 and that does it. | |

| OOPS!! I stand corrected. I happened to plug a 2 in c9r5 and the thing just fell apart, but when I went back and tried a 7 at that location it wouldn't solve so I guess I have misunderstood the rect ... | |

| This was a funny situation. 27 in c3r5r7 and c9r5r7 means that there is NOT a unique solution to this puzzle. Simply put in a 2 or 7 in any of those 4 cells and it just falls apart. | |

| To Marty R. Thanks; I 'm not very good with the x-y thing.. I might have noticed it if the 16 in r5,c1 had been in c2, but then again maybe not. that logic is a bit beyond my experience level. Ju ... | |

| To Tracy and David. There is an x-wing of 1's at r3,c3 & c8 and r6, c3 & c8. This eliminates 1 at r6,c4 and makes r1,c4 a 1 and of course a 6 at r1 c6.. Those were my last two numbers before ... | |
