Another puzzle in the spirit of the Density™ puzzle. This one is initially easy but (I think) subsequently hard. Enjoy!

Final answer: (1,5,2,4)


The last row represents $12$ letters.

Hint 2:

The first row has $4$ multiplication equations.

Hint 3:


Hint 4:

The second row has $2$ words that hint at $2$ words in the final answer.

  • $\begingroup$ The title leads me to assume that the coloured blocks represent (ROT13) vapbzcyrgr cnyvaqebzrf. I have no idea how to decipher what they are, though. $\endgroup$

  • $\begingroup$ Can't see past rot13(KZNF naq NAGF sebz gur obggbz yvarf hfvat greanel gevcyrgf) right now. Either of those of any relevance at all?! Not seeing an immediate connection...! $\endgroup$

  • $\begingroup$ @Stiv What you found so far is all relevant! You are missing rot13(n Zbefr pyhr) though. $\endgroup$

1 Answer 1


Okay, I believe the answer to this puzzle is:


Why? Well, first of all note that the title is:

The start of a famous palindrome (A man, a plan, a canal... Panama). This made me think that we might be looking for a palindromic answer.

Line 1:

This is a set of multiplication equations, where each colour can be substituted by a number. Ultimately this yields: blue = 0, green = 1, yellow = 2 (since green^2 = green, blue × anything = blue, and the 'Ternary' clue would require the third digit to be 2...).

Line 2:

Two clues are hidden here. 1. Reading the dots and dashes as Morse code gives SPACE. 2. Splitting the coloured segments into four groups of 3 gives the ternary equivalents of 24, 13, 1 and 19, which in A1Z26 spells XMAS.

Line 3:

Two more clues are hidden here. 3. Reading the dots and dashes as Morse code gives 6222. 4. Reading the coloured triplets as ternary gives 1, 14, 20 and 19, which in A1Z26 spells ANTS.

How do we put all this together?

We know from the hints that XMAS and SPACE clue two words in the final answer. Also note that the digits of 6222 sum to 12, which is the total number of letters in the final answer... Is it too big a leap to guess that pairing 6222 with ANTS suggests our answer should have 6 A's, 2 N's, 2 T's and 2 S's?

What can we make from these letters that fits the themes of XMAS (Christmas) and SPACE? 'SANTA' and 'NASA' spring to mind. Slotting these into the appropriate spaces in the (1, 5, 2, 4) answer format and treating it as a palindrome automatically uses the leftover letters and yields the final answer: A SANTA AT NASA!
