This was rated 6 stars, and I couldn't dub it into Pappocom:

Obviously, I wasn't able to solve it.
By the way, how do you insert this from the keyboard? |

This puzzle was in my newspaper as well on Saturday.

You could apply an XYZ-Wing to get [r4c7]<>4, but this won't help. Also, Multi-Coloring will result in [r5c8]<>6, but it doesn't help either. However, an XY-Chain on [r1c2] will crack it.

Good move daj... Here is the exact move:

Code: Select all

r1c2=6 => r3c1=1 => r2c9=1 => r5c9=9 => r5c2=6
Therfore r1c2<>6, r1c2=9

Thanks for the help. I can see the logic after the fact. I'd still like to know how to create " | " with the keyboard. I always have to cut-n-paste to get it on my candidate grids. Maybe it's covered in posting grids?

I'd still like to know how to create " | " with the keyboard.

The "|" is typed by Shift-"\" in my keyboard, the key should be near the "Enter" key (it may appear as a broken vertical stroke), but I'm not sure if it's the same everywhere. Anyway if you use a program such as Simple Sudoku it's very easy to cut-n-paste the grid (with pencil-marks or not) to notepad...

Thanks for the explanation, udosuk, it works perfectly. I was having a lot of trouble dubbing in the "oldfashioned" way. ||||||||

On some keyboards the | is down on the bottom left, near the left-shift key and is accessed by [Shift]\. Not to be confused with ¦ which is [ctrl][Alt]top left key.
