It's laziness on the part of MoS - they don't have to check every answer in the grid, just one number at the end. And they make money out of you because you have to pay extra to text or phone and they get a share of that
How can we complain about this? It means I can't send in the Bare Bones and Prize crossword anymore as they back onto each other. I don't have the ability to text.
Puzzler - it look to me that if you cut along the line of the prize crossword you would still have the whole bare bones one one the back. Just put a note in to that effect or if poss photocopy one side. Others must have the same problem
