Here's where Im stuck:
- Code: Select all
| 2 34 5 | 136 14 16 | 8 79 79 |
| 346 8 7 | 2356 9 256 | 2456 1 25 |

| 469 47 3 | 268 278 268 | 1 5 479 |
| 156 57 16 | 4 3 9 | 26 2678 28 |
| 469 2 8 | 156 157 156 | 3 679 479 |
| 8 6 29 | 7 25 3 | 259 4 1 |
| 7 1 29 | 258 6 4 | 259 3 258 |
| 35 35 4 | 9 128 128 | 7 28 6 |
In one of my attempts, I filled in row7 completely but I couldn't duplicate the feat and still got stuck.
This is ugly and I apologize.
if you click quote on the top of this post you will see how its done. if you quote something in code everything is monospaced
e.g... 1 2 3
- Code: Select all
1 2 3
so as long as everything is the same amount of spaces apart, the code looks pretty.
like em said look at where the six goes in the top line, so you know where the six is in box 2, hence can delete 6 from cells in Rows 2&3 in Box 2.
This leads to a Naked pair in Row 2, which leads nicely to a naked single.
From there its basic sudoku stuff to solve
Jetshack,
If you are going to post the solution at least say how you got there using logical steps, what Hud was asking for was the next step not the solution, as the solution is no help to him
