Puzzle: The Village and Sinners

by ,

Hopefully, this is the first of many puzzles to come. We’ll start off with one from Skorks. It is reproduced here:

There is a village full of people. One day the priest gathers all the villagers together and declares that their God has told him that some among the villagers are sinners. All sinners will be marked with a sign on their forehead so that all other people will be able to see if a person is a sinner or not, but no one will know if there is a mark on their own forehead. Furthermore, the mark will not be visible in the mirror and one person is forbidden from telling another if they are a sinner. The villagers must work out which among them are sinners at which point all sinners are to leave the village. The village has been given one week and if at the end of the week, there are still sinners present, the whole village will be destroyed.

The villagers go about their own business during the day, however the whole village gathers in the square at the end of every day so that everyone can see if there are still any sinners left among them. After the third such gathering all the sinners pack up their stuff and leave the village.

How many sinners were there? How did you arrive at that number?

The Introduction of Puzzles

by ,

I have had the alirazeen.com domain for a few years but until now, I didn’t use it for anything. Well, there was that one time my friend, Rollen, and I, were in the school library, trying to quickly design a page that will generate a random string for people to use as their password. For a while, if you visited this site, all you would get is a random string. I think my friend’s page still returns a random password. Other than that, this was just a parked domain.

A few weeks ago, I had a faint idea of what I wanted to do. Two days ago, during my daily browsing, I came across this article and that did it. Ladies and Gentlemen, I present you: Puzzles!

I like puzzles and brainteasers, especially those logical and/or mathematical in nature. I am not very good at solving them but I find it very interesting how these puzzles are so elusive. They have answers but they always escape me. I usually attempt them mentally and give up ten minutes later.

I figured I needed a more structured approach in solving them and decided that one of the regular features here would be puzzles. I would post them, have a discussion and try to solve them. When I run into puzzles I cannot solve, you can post a comment and we can try to solve it together. You can also email me if you find any interesting puzzles. I think we will have fun doing this and perhaps our ability to think well would help us do things better in our daily lives.

I will start with one tomorrow and I will try to post at least on a fortnightly basis.
