Hi crackabilly, would it help if I gave the position of the 7 clashes as (x,y) coirdinates.? It wouldn't take me long as I still have the PDF on my phone.
Sorry, ginge, but what do you mean by co-ordinates of (3,12)? If 12 is the y - the vertical - I end up outside the grid above the square where 3d begins.
Sorry for the delay in replying Orson but my battery died. If you consider the most southwesterly square of the grid as (1,1) and the most northeasterly as (13,13) ie reading from left to right and starting at the bottom, (1 right, 1 up) and (13 right, 13 up) respectively that should make things clear (grid position irrespective of clue number).
