Above is a cross-figure to complete. However, there are no across or down clues. Instead you have to ensure that:
a) if an answer uses one of the numbered squares then that answer must be divisible by the little number in that square (for example the five-figure number in 1 down must be divisible by 1, 4 and 7; similarly the five-figure number in 7 across must be divisible by 7);
b) in your answers, only two different digits can be used throughout, one of them odd and the other even;
c) the odd digit must be written at most once in any row or column of the grid.
What are the answers to 1 across, and 7 across?
Currently the online version of this puzzle seems to be missing a title. I shall update it if it is updated on the New Scientist site, or when I get my paper copy of the magazine (probably Friday).
Enigma 1316 is also called “Clueless”.
