You are a citizen of Grid Land and your job is to keep everyone safe. The Big Flood struck and the sums of each of the coordinates are: [10, 6, 4, 2, 10, 8, 100, 29] and you will have to decode it.(Dummy Mayor because he didnt put the actual ones...) One thing for sure is that all of them share t...
In the spirit of some of my Raymond Smullyan favorites, here's a relatively hard puzzle from a Dennis Shasha collection of $1988$:
Eight kids and their guide are lost on a forest exactly one hour before night falls. They are on a glade from which four paths leave. The guide knows that one of the...
There's a broken clock. the interval between its two ticks is longer than usual so that it loses 6 minutes an hour.
How many ticks should a blind person hear so that he/she be informed of real 6 minutes past?
I have asked this question recently. It's more likely a puzzle; because I have seen it in a puzzle quiz. Also, a math problem isn't asked in this way!
Compare it to this one. This is really like a problem. it is dealing with technical mathematical staff like triangle's incircle.
But since the ask...
This is an extended hybrid connect-wall puzzle which fuses components of the most common PSE strain (where group connections also have one final connection, which is the puzzle's answer) with a variety of connecting methods used in the original BBC TV series, Only Connect. This means that not all...
(This is my original puzzle) Can you work out the number that fills in the question mark?
1,9,216,10000,?
Find all solutions to
$$\begin{array}& & & &E&A&T\\& & &A&T&E\\+&E&A&T&E&N\\\hline&Y&U&M&M&Y\end{array}$$
Where different letters represents different digits from $0$ to $9$.
Problem by myself
9 points are drawn on a piece of paper with the following rules:
Each point has integer coordinates $(x,y)$ that are between 1 and 10 inclusive.
For each point there is exactly one other point so that their x-coordinates or their y-coordinates match.
Two points cannot sit on top of each other.

A who-am-I riddle
It can be said:
To be gold is to be good;
To be stone is to be nothing;
To be glass is to be fragile;
To be cold is to be cruel;
Who/what am I?
5 independent problems in a "self-help arrangement" (which helps you figure out, what the task is, without presenting an example)
not left + up = honest
tear + boy = jail
five + I = kiln
recursion + maize + confident = recursion
uncommon/back + rage/span = anagram
How do I solve this double parity?
Can both be solved at once OR need to solve center parity first and then corner parity or vice versa
