I've been using the Dev version to help me learn more solving techniques. I asked for a hint at this point in the puzzle and received 8 in in r4c1 but the app couldn't explain why. Can anyone explain?




Code:

+---------------------+-------------+----------+
| 28     248    15    | 6   148 7   | 9  15  3 |
| 1689   7      1569  | 389 138 139 | 2  15  4 |
| 3      149    19    | 2   5   149 | 8  7   6 |
+---------------------+-------------+----------+
| 168    5      4     | 7   9   136 | 16 38  2 |
| 126789 123689 13679 | 4   138 136 | 16 38  5 |
| 168    1368   136   | 38  2   5   | 4  9   7 |
+---------------------+-------------+----------+
| 5      39     8     | 39  6   2   | 7  4   1 |
| 179    19     2     | 5   47  49  | 3  6   8 |
| 4      36     367   | 1   37  8   | 5  2   9 |
+---------------------+-------------+----------+

Karin,

Look for a quad in box 4.

The "app" left a cryptic hint.

If you examine the values <1> and <6> in [row 6], you'll see that they are locked in [box 4] and can be eliminated elsewhere in [box 4]. That only leaves <8> in r4c1.

Regards, Danny

Karin,

Sudoku Susser is a great learning tool. Search on Google, it is a free download.

To load a Daily Sudoku puzzle, just right click and copy the image. Paste (Ctrl+v) it in the Susser window.
