The puzzle below is part of a Puzzle Crime Story I have started on my website, but will skip the details here (you can see other puzzles from the series here and here). In short, you have the following rectangular card which has the word "SIN" written on one side and a bunch of letters/symbols on the other. You must figure out a 4-digit number encoded in the card. I am sharing the puzzle here because I've noticed nobody has figured it out yet and want to decide whether to simplify it a bit.

    $\begingroup$ When going from the front to the back, did you flip the card over left-to-right or top-to-bottom? $\endgroup$ May 9, 2016 at 4:55

    $\begingroup$ Yeah, that's important - left-to-right. $\endgroup$ May 9, 2016 at 4:57
  • $\begingroup$ Answered in less than a couple of hours. I guess there is no need to simplify it? Maybe you just need to add a carefully phrased hint? $\endgroup$

    $\begingroup$ I got sidetracked by reading the N's as Z's (which made the anagram step not work). Up to you whether that's something to change or not. $\endgroup$

1 Answer 1


The back side is:

An anagram for PUNISHMENT

Rearranging the letters to match transforms the front into the numbers:

    $\begingroup$ @Will Yeah, I'm a computer guy but I figured this one would be faster on paper. $\endgroup$ May 9, 2016 at 5:19

    $\begingroup$ @Devsman in my story there is a killer who murders his victims for their sins. This particular one has been greedy. $\endgroup$ May 9, 2016 at 14:00

    $\begingroup$ I think you can assume "Greed" as a hint too. Except its main meaning according to story, it can be the misspelled word "grid", which is a hint for rearranging the paper cells. $\endgroup$
