1 Answer 1


Each number spells out Braille letters using the number to dot correlation in braille. enter image description here

And so:

The five numbers spell P,U,E,R,T,O so you are looking for R,I,C,O to make Puerto Rico the country. Also there is a priority in the numbers. So the numbers are 5312, 42, 41, 531

    $\begingroup$ I suspect it's because (a) it's a number sequence and these tend to score low on PSE, (b) the ordering of digits within each number seems pretty arbitrary rather than based on anything recognisably clever, and (c) it was only solved after a very revealing hint was added, when a clever hint word could easily have been concealed in the flavourtext from the start - the path to the solution lies in the hint, not the puzzle body itself. $\endgroup$
