hello sudoku community,
I started playing sudoku a few days ago, with a easy one printed in our
daily newspaper. I solved a few easy and medium puzzles, very funny !
then I started to solve a harder one, but I'm stucked. If someone could
give me a little hint...
current state:
*46 *8* 2**
**7 5** 3**
**9 *** 6**
493 *2* 756
728 **5 143
561 473 9**
*75 *** 4**
**4 *57 8**
**2 *1* 57*
the blue ones are own, black were set.
thanks in advance,
Georg.
