I made another Density puzzle. This one is a bit simpler than my last one in that it has less steps, but at the same it feels a bit harder (though I can't judge that accurately as the creator). Here it is: enter image description here

Solution: (8,8)

Hint 1:

The background colors are not arbitrary, as @Jens so brilliantly realized. In fact, they are very specific.

Hint 2:

To solve the dots, remember that Morse code has very specific rules for its use.

  • $\begingroup$ That is exactly right. Good job! $\endgroup$ Commented Dec 19, 2019 at 1:21
  • $\begingroup$ I have to ask because of "steganography" tag - is there a message in "dots", and only "dots" are enough to create half of solution? $\endgroup$

  • $\begingroup$ The steganography tag is there because the answer is "hidden" in the image. To answer your question, however, yes, the dots are just a part of the solution. $\endgroup$ Commented Dec 19, 2019 at 15:19

    $\begingroup$ They are uneven, but that was just laziness on my part; it's not a clue in any way, shape, or form. $\endgroup$ Commented Dec 19, 2019 at 21:01

1 Answer 1


Solution is:

Untitled document

First part:

Morse in dots, where one black dot means "dot", and three is "dash". Three white dots are separator - UNTITLED

Second part:

What Jens found was close. Colours in this order as RGB are:
Which is in base-3 letters: ZCNBTLDMS
With shift by one (or caesar cipher +1) it is: A DOCUMENT

  • $\begingroup$ You got it! However, you didn't need to do the shift. It may be different from how other people do it, but when I make puzzles, 000 = A and 222 = _. $\endgroup$ Commented Dec 20, 2019 at 13:00
