But maybe its because I do them on paper. But today I had some time on my hand and I started experimenting with the SudoCue program. And I picked the September 22, 2006 Windoku.
I filled in my (few) findings and compared the markups to my paper version. Well, I found 4 cells where I missed to eliminate some digits (all in column 9), but also had a naked triple in row 1 and the "5th window" (or what's your name for the special corners) that wasn't (yet) found by SudoCue.
Long story short, that's how far I got:

SudoCue marked the cells, they are shown above like this:L Stiles found a Naked Triple with Digits {3,5,9}
Additional explanation from the log:
Because these 3 cells in L Stiles only allow those 3 digits, they cannot be placed in other cells in L Stiles
Y - Yellow (R1C34, R9C4), R - Red (R9C3), B - Blue (R159C2, R5C34)
So this hint tells me to remove the 5 from R9C3, correct? But why? I don't understand this technique or its name. Or maybe it's just too late. Could please someone explain it to me?
I paused my game at this point and will try to resume it on Sunday (Saturday is now mostly Clueless-day, sorry). Nevertheless I will visit the forum regularly.
Thanks in advance,
Peter
