If you ask for a hint from the program you can make it through even the most befuddling of puzzles. On Thursdays I took a hint and from there it was easily solved.
But can anyone tell me how a #1 can be positively excluded from the square where the hint was?

Here's the layout. The hint given was the 5 in R7 C3.

x69 357 2xx
3xx 962 57x
xxx 184 963

9xx 845 6x7
x5x 736 x29
6xx 219 xx5

735 698 xx2
x96 423 7xx
xx4 571 396

Hi there,

If you look closely at Column 3, you will see there is a pair of 1,8 in cells r2c3 and r5c3. This then means you can exclude all other 1s and 8s from Column 3. Since the only possibilities for cell r7c3 are 1 and 5, this means the 1 MUST be excluded, leaving 5 as the only possibility.

Hope this helps,

Cheers.

Would you be interested in tutoring me through one from our local paper that's still giving me trouble?
