Take a close look at row 6... where can the number 4, and the number 9 go?

What does this mean for the number 1 in box 4? where can the number 1 go in it?

Curiously I got a little further than Eeyore albiet down a sightly different path.

2*7 98* 516
196 7** 834
*85 *** 279
7** *** *61
621 479 385
85* *** *27
912 537 648
*6* *9* 752
578 *4* 193

I seem to be struggling with column 6 and can't work out how to isolate the 4 in r1 the 6 in r3 and 2 in r9.

Tips?

Perhaps it was just a typing error but you don't seem to be using all the information that was originally supplied.
Row 3 column 6 is a '6' because that was given to you from the very start.
Hope that helps.

I hate that.

At least it prompted me to write a couple more routines from my excel solver.

Thanks-followed your suggestion and solved it by logic
