Got stuck playing on http://www.sudokufun.com with game #4592
I got to this point :
Code: Select all
6 3 2 | 8 5 4 | 1 9 7
0 4 7 | 0 0 9 | 0 6 8
0 8 0 | 0 6 7 | 2 0 0
------+-------+------
0 1 0 | 0 0 0 | 7 0 9
3 7 0 | 0 0 0 | 0 5 2
4 0 8 | 0 0 0 | 6 1 3
------+-------+------
0 0 1 | 6 0 0 | 0 0 0
8 5 3 | 4 0 0 | 9 7 6
0 6 4 | 0 8 0 | 0 2 1


And I absolutely don't have any idea on how to go on.
Anybody cares to help ?
Thanks

Have a close look at column 7. Cells r2c7 and r9 c7 are a pair. Only a 3 or 5 can go in these cells one way round or the other.

This means that you can eliminate 3 and 5 from r7c7. This will allow you to enter a big number in r7c9 and then complete box 3. That should get you going a little.
