Hi

Can you help me out on the above.

From the example below can you establish WXYZ on 2359 which eliminates 3 in C4? (and a 2 if there was one in the that cell) Its just that I know there are caveats when the outlier cells contain pairs etc.

Thanks for your time. (sorry about the quality of the grid)

Code: Select all

B   6   12   13   4   239   8   1239   5   7
C   1359   8   1357   37   2359   6   129   4   239

This is a more properly aligned text format of your band:

Code: Select all

 3459  245  3457 | 1   2359  279 | 2369  8  36
 6     12   13   | 4   239   8   | 1239  5  7
 1359  8    1357 | 37  2359  6   | 129   4  239

I don't think you can validly eliminate 3 form c4 from this information.

Alternatively, try to load this grid into Simple Sudoku:

If you put 3 into r3c4, there is no immediate contradiction resulted. So I don't think you can make that elimination.

If you have a full grid where you suspect that elimination can be made, please post it.

Thanks for your help. I honestly thought that the 3 in C4 was vulnerable cos it could "see" all 4 cells of the naked quad 2359 and each of these cells contain a 3.

I thought that the wisdom on WXYZeee was that you just had to watch for naked pairs etc in the outliers.

Thanks again.
