I need your help! My friend has gone missing and I have no clue where he could be! However, he did manage to get a message out to me:

Kidnapped. Send help. I am here:

port town. $\left\lfloor\sqrt{\frac{x}{500334.5}}\right\rfloor$, add $^{\circ}\ '$

- Rick

P.S. Remember my favourite three things!

Obviously, he hid the location, and that is where I need your help. To aid you, I vaguely remember him mentioning his favourite three things as fonts, the number 18 and the OEIS.

To send for help, I need both the city and country that he is currently in. Thanks for your help!


Only the bold bits and the formula are relevant to the puzzle.

Extra notes (hints):

It turns out Rick was able to send another note:

Try writing the special part of the original message in a different font.

- Rick

And another:

When you find the two hidden numbers $x$ and $y$...

- Rick

    $\begingroup$ @mestackoverflow quite sure it is relevant. The degree and apostrophe look like they denote map coordinates. $\endgroup$

    $\begingroup$ You can get some numbers from 'port town' if you change the font to Wingdings 2. $\endgroup$ Jul 8, 2016 at 23:29

I think he is in:

Grado, Italy

port town:

It's italicized so that represents Italy, and it's a port town

formula and add:

I have no idea how that factors in

degree symbol:

Degree in Italian is "Grado"; hence Grado, Italy


again no idea

I'm not sure, but is your friend is in

France in Le Havre?

I vaguely remember him mentioning his favourite three things as fonts, the number 18 and the OEIS.

Searching for word OEIS, give me On-Line Encyclopedia of Integer Sequences

When I cross reference name of sequences with fonts, I found weird font and sequence.

I used 18th number from weird sequence (13510) in your formula, and that give me number 0.1643226573

and I draw lines on map with latitude and longtitude 0.1643226573.

Le Havre was biggest port town on my line, and hence my pick.

  • $\begingroup$ Nope. Sorry. Not in France. $\endgroup$
