Please!!
I've put what I've got so far into one of those Sudoku solver websites and asked for a hint. The hint says a particular square can be solved in 4 ways "easily" but I just can't see any of the ways 
I'm quite experienced and usually do the difficult ones.
Will I put the details in here and hope someone can come to my aid.
So it goes
3* 8* **7
*8 7 39
6 53 28
82 3*
1 6* *3
63 4 8
34 7* 1
8 52 6*
56 * *8
I've now abandoned the website but I think it was the 4th square across in either row 5 or 6 that was "easily solved" - but not easily to me!
It also rated the whole puzzle as easy to complete, so that's making me feel rather thick.
