Look at column 6, if you look cairfully you will see something.

Now take a look on box 5, and remember what you saw in column 6.

(also, next time it might be better to post these puzzles in the 'Times Sudoku Books'-part of this forum)

Hi
Read your note this morning. I checked my book and I too had difficulty solving this one. Tried it again and glad to say it does work and doesn't require any guessing. Really focus on the top left square. See what can be eliminated. Good luck.

You're looking for the pair: 3, 7 (or 2, 6, and 8 but which ever you choose the result remains the same)

A pair of cells is where you can find 2 cells in a box, row or column that can only have 2 possible numbers in them. Pairs are extremely useful as they mean you can rule out those same 2 numbers being anywhere else in that box, row, or column in question.

Does that make sense?

@ Animator,

I have looked at column 6 of that Sudoku - but it didn´t help me,

the Sudoku looks like the following:

Code: Select all
+-------------+--------------+----------+
|568   3  258 |2569 1269 268 |7   4  15 |
|456   45 245 |236  1267 2367|9   8  15 |
|19    7  19  |4    8    5   |6   2  3  |
+-------------+--------------+----------+
|2     8  1345|35   57   9   |45  17 6  |
|579   6  59  |1    257  4   |258 3  28 |
|13457 45 1345|8    2567 2367|245 17 9  |
+-------------+--------------+----------+
|48    9  6   |7    3    1   |248 5  248|
|3458  2  3458|56   456  68  |1   9  7  |
|458   1  7   |259  2459 28  |3   6  248|
+-------------+--------------+----------+


I don´t know which numbers I have to look for in column 6 - the missing numbers in that column are 2,3,6,7 and 8
