difficulty rating 17 provided the Brukheim principle is adhered to
Struggled for a while until I found a triple, then it came together nicely.
slow start, easy finish
To easy for a hard
the triple was tough. If you're stuck, the 997th digit of Pi is a 1,2, or 3 meaning row, column box; the 980th digit of pi is which of those has the triple
My computer working very poorly. But I managed to ask Taskmanager to start up Firefox, and here I am with Ironsudoku.
somehow I have managed to screw this one up not once, but twice, so I will bbl
Be Basically Laidback?
Found an instance of a new technique I've discovered. Forbidden pair formation. Sometimes when one number is removed from two places in a constituency, it produces pairs that are impossible. Therefore those numbers must not be removed. Instead, remove any number that might cause them to be removed.
done. g+r auto greens, then the triple.
Unike, that's interesting.
Oh brother! I can't find the triple everyone is mentioning. And I'm getting too tired to continue.
don't look too hard... it's in the clear.
UTH, I think I know what your new technique is. If you look at it again I bet you will see that you really found a naked pair in a block, not on the same line.
Awesome, I'm almost three weeks behind now.
Guess I'd better get to work on these
New technique sounds a lot like Aligned Pair Exclusion from the description I see here.
Or maybe a new variation of Nishio.
Difficulty score 44. I recommend using green on this one. Like everyone says there is a triple that opens things up.
Difficulty score is 27 on the Freyerhoff scale.
AND Nishio is a fake!
not that terrible, just don't forget whatever it is called, like a triple o aligned pair, you already know it.
Yes Angie, Nishio is controversial. But by what metric did you rate this puzzle a 17 earlier today? And how does the Brukheim principle affect the difficulty rating?
finally got it
after one wrong guess... and some heavier thinking, this puzzle revealed itself ... without any greens as i never use greens...an interesting puzzle !
i finally made the NEWBIES yesterday... albeit, the very last line...
