Hi. Can someone please check this one for me:

This is the original, printed in a paper I suspect use non standard puzzles (the question is copied from a Norwegian forum):


*** *68 9**
*** 5** *4*
**6 *14 2**

421 *5* 869
*** *** **1
**8 **2 ***

**5 **9 ***
9** 8** **2
**4 **1 5*6

This is how far I got:


*4* *68 91*
*** 5** 64*
**6 914 2**

421 *5* 869
*** 486 *21
6*8 192 ***

**5 6*9 ***
96* 845 1*2
**4 **1 596

I really find it annoying wondering whether it is my logic or the puzzle there is something wrong with.

Help is appreciated beyond telling me what to look for... (I wonder if the triplets I think I'm seeing are for real, for instance. Row 6 from the top: I want to place 7 in between 6 and 8 in the box to the left. This places 7 next to the two in the right box in row five. Am I imagining this or on the right track?)

Thanks so much.

The grid you have posted has multiple solutions; 44 to be exact.

Thanks for that, Scrose - along the lines I was expecting. Is there a clever way of seeing what is a "false" puzzle?

No, there is not an easy way to spot if a given puzzle has multiple solutions; I used rubylips' solver.
