Hi, welcome to the forum.
Code: | +----------------+----------------+--------------+
| 3489 2349 2489 | 1 2589 589 | 6 7 359|
| 789 1 789 | 3 5789 6 | 2 589 4 |
| 6 239 5 | 4 2789 789 | 1 389 39 |
+----------------+----------------+--------------+
| 479 8 3 | 79 6 14579 | 59 1459 2 |
| 5 6 2479 | 279 1279 1479 | 3 149 8 |
| 1 249 249 | 289 3 4589 | 7 6 59 |
+----------------+----------------+--------------+
| 89 5 1 | 6 89 3 | 4 2 7 |
| 2 349 489 | 5 1789 1789 | 89 389 6 |
| 389 7 6 | 89 4 2 | 589 3589 1 |
+----------------+----------------+--------------+ |
In box 3, you need to remove the 3 from column 8. In box 9, you need to remove the 8s from column 8. In box 8, because of the 89 pair, you can remove the 89s from row 8 in box 8. In box 5, the 2s and 7s may be removed from columns 5 and 6. You might check around and see if there are more similar moves. I didn't check everything. After you make the eliminations, there may be some moves that are apparent.
If not, don't hesitate to ask again. |

In row 5, the only possibilities for 9 are in box 5. Therefore, in box 5, you may remove the 9s from rows 4 and 6. That should allow you to make some progress. Good luck. |
