This is a true story... Today I am at home looking after my daughter who is off sick from school. We spent some time this morning playing with LEGO and built a house. Not just any house though - because somehow among our brick choices we've managed to encode the name of the street on which you'll find this house...

So based off the following picture, tell me:

What is the name of the street, as indicated by the sign out front?

enter image description here

With apologies to those with colour-blindness who may not be able to view the image correctly... The 10 coloured bricks within the sign are (from L to R): green, light blue, brown, lime green, clear, pink, navy blue, sky blue, yellow, orange.

1 Answer 1


The answer is



This is binary (00100) or Bacon's Cipher (aabaa) for E

Light Blue:

Per @hexomino, if you look at the group of nonmetals on the periodic table, you get CNO (6, 7, 8) and PS (15, 16), so the missing letter is N

I still think it just looks like a chunky/blocky letter N (from lower left trace up, right, down, right, up).

Brown (FINALLY):

Scrooge is holding his brown canes like the Flag semaphore for A

Lime Green:

The 12th letter of the alphabet is L


Just a space


This looks like the K block from a normal pigpen cipher

Navy Blue:

I think this is just the letter C, as the 3 nearby letters (O, P, S) look like a different color

Sky Blue:

There are 9 sky blue bricks, and I is the 9th letter of the alphabet. Thanks @mihomir!!


The windows look like Braille for the letter R


The orange bricks look like Morse Code for the letter B

That produces:

Since the arrow points right to left, switch the order to BRICK LANE

    $\begingroup$ A brilliant start :) There is stronger logic to support the N (I wouldn't say it looks like one...) - use something you haven't used yet (but have mentioned...). Keep looking for the brown and sky blue (don't overthink that one...). And yes, as per the final letter I was thinking this... $\endgroup$
