1341996 2013-05-19 23:31:00 Where does the 5 go and why?

(A free modem to the first person with the correct answer ;) )

1341997 2013-05-19 23:44:00 Based on what's immediately visible, it could be either the top left or top right empty squares in the left large square, or one of the squares with 5 already in them. :p pcuser42 (130)
1341998 2013-05-19 23:45:00 Hmmm, it's bugging me now, specially trying to figure out the "trick".
Logically it's on the top line in the left square but that leaves 2 options, assuming of course the written numbers are all correct.

1341999 2013-05-19 23:46:00 yeah and wont it depend on which one so you need to see the left squares below? Gobe1 (6290)
1342000 2013-05-19 23:49:00 No it's not an existing cell with a 5! (but marks for trying PCuser42)

It does have a definite answer on the information presented (and on the rules of Sudoku)

1342001 2013-05-19 23:53:00 Ok bottom left coz the 5 is in the wrong place on the right... hahaa Gobe1 (6290)
1342002 2013-05-19 23:58:00 Ok bottom left coz the 5 is in the wrong place on the right... hahaa
No, everything is correct so far. It's not that tricky

1342003 2013-05-20 00:04:00 top left of left box. Iantech (16386)
1342004 2013-05-20 00:09:00 top left of left box.

I thought so too, but there's nothing stopping you swapping the 5 & 6 or the 6 & 9 in both boxes. the 3 & 8 make no difference either way they could go.

1342005 2013-05-20 00:16:00 No, but Dugimodo inching towards the answer

(The answer has similar level of quirkiness to the old kid's puzzle

Make a square by moving just one match: )
