In the Netherlands? Interesting.
If you think about it, we in America have certainly borrowed a lot of place names from around the world.

Hi chiefmsb,

SE (or ER) 7.6 meant: difficulty rating of Sudoku Explainer solver. Find the same name (sudoku explainer) on Google and download to install.

This is a nice solver for learning, you can use it to solve puzzles or generate new puzzles... For its rating: use More...

1. Unique possibilities to 27.
2. If e3=6=g8;row 9 is devoid of 6.So e3=1.UP35.
3. If g4=3,g3=7,d8=9=e4=c7;b4 has no candidate.So g4=7.UP37.
4. Whether e4=9;OR e4=4=c7;b4=3.UP38.
5. Whether e4=4;OR e4=9=c7,c6=7,a6=8,a5=4;a4=5.UP39.
6. Whether b1=7,a6=8;OR c2=7,c6=9,c7=4;a5=4.UP53.
7. Whether i9=4,a9=3;OR i9=3,i6=8,a6=7;b9=7.UP81.

Go Alfred !

But I've got SST UPs to 35 so far. What'd I do wrong? (In order, B2,5,D7,D2,E6,B6,7,8,A9,C9,I9,7?)

Puleeze delete my message above. I'm on the wrong day, of course.

Brenda, please check your labelling system.b6 is already 1 . I make b2=5,b7=2,c9=5,i7=5;UP27.Then e3=6 leads to a contradiction,so e3=1;UP35.
Regards, Alfred.

Oh anguish and mortification! (Actually I meant "disregard" but that's how brain dead I was at the time. Hopefully I'm over whatever it was. I've got a lot to do today, including what I couldn't doyesterday.)

Regards to all,
Nice times lately,
And thanks, Sotir, for those pointers to the explainer-solver-rater. Very interesting.
