If anyone is looking to practice their very difficult Sudoku solving techniques, a slight variant of this puzzle is unique, but appears to be much harder (according to Scanraid). Take this puzzle, but only put an 8 in the middle square (erase the 5 and 2 from f4 and d6).

I haven't sat down and done this yet, but it seems to go quite a bit into the "evil" strategies there, so it might be a fun one for you to try.

My girlfriend has to wait a few hours for her plane to arrive, so I sent her this one by sms.

I only for the third day have solved it. But when it was defined that in C8R7 (h7) not "1", but "7" the puzzle decision has gone like clockwork further.
