For my first question here, let's start cool with a little sketch.

The enigma.

No, it's no hard brainstorming, no, it's not a revolution, yes, I had to start with something :)

    $\begingroup$ Nice puzzle! Fun to solve, and very self-confirming. $\endgroup$ Feb 11 '17 at 19:41
  • $\begingroup$ Hey, @Mithrandir, sorry for answering too late :/ $\endgroup$ Feb 11 '17 at 19:57
  • $\begingroup$ @randal'thor Thanks ! I've got ideas in this way of thinking - those are chase recreations more than real enigmas, but I find it always fun to solve, even when there are no hard-hard challenges. Up to me to build hard versions with this kind of stuff ^^ $\endgroup$ Feb 11 '17 at 19:59

Partial answer

  • Sudoku:


  • TinyURL link:

    Perhaps those arrows signify specific squares in the Sudoku? Starting from the top left corner (marked with the big dot) and proceeding sequentially in the directions shown, we find DBDCDA, giving tinyurl.com/DBDCDA which redirects to this page. (Thanks @Deusovi for help with this clue!)

  • Cuboid:

    A 1cm by 1cm by 2cm block is 2 cubic centimetres. According to Wikipedia, lutetium has a density of 9.841, so a 2-cubic-centimetre block would weigh 19.682 grams.

  • Coordinates:

    Substituting $ef,ghi=19,682$, we find (33.006167, -79.983557), which are the latitude and longitude of a road called Bravo in what looks like a housing estate with roads named after the words of the NATO phonetic alphabet, somewhere in South Carolina, United States.

So the final answer is

    $\begingroup$ @Kevin And I even took the time to draw up a new Sudoku grid from scratch! :-) $\endgroup$ Feb 11 '17 at 19:24
  • $\begingroup$ :) Only saw the question a few minutes ago. Ah well, will remove my answer in that case. Btw, is your ABBBB correct? Maybe it starts at the dot and going south-east means D is the first one, and you continue from there, resulting in DCADB. Although the resulting page doesn't make much sense. $\endgroup$ Feb 11 '17 at 19:28
  • $\begingroup$ It's DBDCDA, which leads to fr.wikipedia.org/wiki/Lut%C3%A9cium. $\endgroup$

  • $\begingroup$ @Deusovi Ah, including the D, that's also a possibility. And that page indeed makes more sense than the one I had. $\endgroup$ Feb 11 '17 at 19:31
