The New Sudoku Players' Forum

[Sandy Kimble]

Can anyone give me a hint where to go next. I've browsed around some references and just learned what an x-wing is, and applied that to get one answer. I also apologize for not knowing how to submit a neatly aligned grid.

I am at this point:

. . . | . 8 7 | 2 9 . |
7 . 2 | 3 9 . |. 8 . |
. 9 8 | . 5 . | . 3 7 |
----------------------------
8 2 . | . 4 . | . . . |
5 6 4 | 7 2 8 | 9 1 3 |
1 . . | . 6 . | 8 4 2 |
-----------------------------
9 . . | . . . | . 2 . |
2 4 . | 8 . 6 | . . 9 |
3 . 6 | . 1 . | . . . |

Hi Sandy

It helps if you post your candidate list as well so we know where you've got to, so the following may include candidates you've already eliminated. I think you must have done the hard bit!

Your grid and the accompanying candidate list are as follows:

Code: Select all

 *-----------*
 |...|.87|29.|
 |7.2|39.|.8.|
 |.98|.5.|.37|
 |---+---+---|
 |82.|.4.|...|
 |564|728|913|
 |1..|.6.|842|
 |---+---+---|
 |9..|...|.2.|
 |24.|8.6|..9|
 |3.6|.1.|...|
 *-----------*


{46}     {135}    {135}    {146}    {8}      {7}      {2}      {9}      {1456}   
{7}      {15}     {2}      {3}      {9}      {14}     {1456}   {8}      {1456}   
{46}     {9}      {8}      {1246}   {5}      {124}    {146}    {3}      {7}     
{8}      {2}      {379}    {159}    {4}      {1359}   {567}    {567}    {56}     
{5}      {6}      {4}      {7}      {2}      {8}      {9}      {1}      {3}     
{1}      {37}     {379}    {59}     {6}      {359}    {8}      {4}      {2}     
{9}      {1578}   {157}    {45}     {37}     {345}    {134567} {2}      {14568} 
{2}      {4}      {157}    {8}      {37}     {6}      {1357}   {57}     {9}     
{3}      {578}    {6}      {2459}   {1}      {2459}   {457}    {57}     {458}   


Naked pair (57) in column 8 - therefore r4c8 is 6. The rest can be completed with singles.

Hope that helps.

Check the Help with particular puzzles forum for tips on how to post a puzzle you're stuck on. I use the copy feature in Simple Sudoku which cleverly enables you to paste within the [code] and it comes out as above.

thanks very much. I'll work on how to post properly.
