Numbers or Letters

Are numbers or letters better for grid square co-ordinates ? Discuss...

Using letters for co-ordinates [Help and suggestions for Sudoku Dragon program forum]

In SudokuDragon the rows and columns are given letters (e.g. see page) rather than numbers. All other Sudoku puzzle solvers I have seen use numbers. I can see that there is some point in making the row and column names easy to use but I think the letters are also confusing. Could the program be changed so that the numbers for rows and columns could be numbers - perhaps as an option ?

Yes, I find the row and column as letters much better. I always get confused by rows and columns (as well as left and right) so using a Capital letter for rows makes it a lot simpler for me.

Square names (re: Using letters for co-ordinates) contributed by Rob Puzzle

It's particularly useful to identify a single grid square. Having to say row 3 column 4 is a lot more long winded than just saying square Cd.
