Hi I am getting better at Sudoku but don't understand the hints on this puzzle.
After filling in the obvious numbers, the 'Hint' function inserted a
'2' at R3C4.

I don't see how you can define this as a '2' from the information you have.
Can someone please explain?

Thanks Rolling Eyes

Claire

Claire, can you post a grid at the point you asked for that hint? You put in the obvious numbers, but what's obvious to one may not be obvious to another, so it's hard to try and determine what your position might've been.

Claire,

Maybe you are here?
Code:
+----------------+----------------+----------------+
| 8    5    2    | 179  479  147  | 6    3    149  |
| 469  3    146  | 5    2469 8    | 124  7    1249 |
| 469  16   7    | 129  3    146  | 8    249  5    |
+----------------+----------------+----------------+
| 1    9    8    | 37   567  2    | 34   456  347  |
| 367  267  356  | 4    1    9    | 23   256  8    |
| 3467 267  3456 | 8    567  367  | 9    1    2347 |
+----------------+----------------+----------------+
| 2    167  136  | 1379 8    1347 | 5    49   1349 |
| 37   4    13   | 6    279  5    | 123  8    1239 |
| 5    8    9    | 123  24   134  | 7    24   6    |
+----------------+----------------+----------------+

Note the 24 pair in R9. After you eliminate 2 in R9C4, R3C4 must be 2 in C4.
