I've been dreaming up potential logic puzzles involving colours, and how they mix to form new colours. This logic puzzle uses the three primary colours (in the additive colour space, how l...
This puzzle is dedicated to Sciborg. Copying the dear gentleperson, some of the 4s are hiding in the corners.
Rules: (Nurikabe section shamelessly stolen from an earlier puzzle by @jafe)
Numbered cells are unshaded.
Unshaded cells are divided into regions, all of which contain exactly one numbe...

Here is a standard Pentopia puzzle.
Rules of Pentopia:
Place some pentominoes into the grid (not necessarily all of them) so that they do not touch each other, not even diagonally.
Pento...
This is continue of A&Q. Let's say there is a regular hexagon with center at point O.
Question. How many self-intersecting polygonal chains are there that connect n=7 points?
The self-intersecting polygonal chain passes through each point once
and chains should be non-isomorphic.
I came across some code and I'm trying to crack the case as to what it does:
for $0 \leq f \leq l < len(A)$, the function is
def foo(A, f, l):
if f == l:
return A[f]
m = (f+l) // 2
x = foo(A, f, m)
c = 0
i = f
while i <= l:
if A[i] == x:
c += 1
i += 1
if c > (l - f...

This puzzle type is inspired by Kakuro, and it has similar rules.
Kakuro is short for 'kasan kurosu' (加算クロス) meaning 'addition cross'.
Using Google Translate, I get 'hōkō kurosu' (方向クロス) w...
I recently did those Skyrise City tests and one of the games caught my eye, the energy one. I couldn't really deduce a logic behind it, just a few clues (one of the generators always gives more energy than the others, for example). Is there one?
There has been a power cut. You must restore as mu...
The 16 words below may be partitioned into 4 groups of 4 connected words.
Additionally, each of the four groups can be represented by a single group-word.
Finally, the four group-words are connected by a single four-letter word.

I found a reality TV show recently that I thought would make a fun puzzle. On the show are 10 men and 10 women that have been "match by experts" (ie. randomly paired). Their goal is to determine which men were paired with which women; either they get all 10 correct and everyone wins or everyone...
A city's roadworks is laid out as a perfectly rectangular tiling. A commuter within this city has to travel to work a distance of $17$ blocks east and $7$ blocks north each day, and tries to take the same route one day as he does the next... with just a touch of novelty. He will choose at random ...
Less of a question than just...
I'm disappointed.
You state:
We understand that this is a change some may be disappointed by and that it may seem to indicate that we don't believe that younger members of our communities can be great moderators - over the years we have known many mods who started...
