I was half-expecting something out of the ordinary when Archie presented me with the cross-number puzzle below. So I was not altogether surprised to see that half of the clues were missing, nor to hear his half-baked explanation of how he had rescued the paper they were written on from the grate in his living room.
1. Seven times 3 down. Also starts or ends with the same two digits as 7 across.
7. Nine times (4 across minus 5 down).
2. Three times 6 across.
4. A multiple (not 1) of 2 down.
All I want to know is: what is the difference between 6 across and 7 across?
