Here's a fun game that everyone can play. One person starts with a riddle, and gives everyone a week to try to guess the answer. Whoever guesses first gets to post their own riddle, and it goes on and on. If no one can get the riddle after a week, the answer will be posted along with a new riddle. Here's the starter: You use a knife to cut my head then weep beside when I am dead

A guy buys a chocolate (from a shop) worth 80 YEN and hands over 100 YEN to the shopkeeper. The Shopkeeper doesn't have 20 YEN to give back the guy. Hence, he goes to the adjacent shop, asks for an exchange to a lady at the cash counter and fortunately he is able to convert 100 YEN into 10 numbers of 10 YEN. He comes back and returns the 2 numbers of 10 YEN to the guy. The guy leaves happily with the chocolate. After an hour or so, the lady from the adjacent shop finds the particular 100 YEN to be a fake one and promptly returns it and takes back a good 100 YEN from the Shopkeeper. (Hope I somehow managed to put it across) What is the loss for the poor Shopkeeper?

Suppose that you are on vacation with two of your coworkers. Now it's time to relax and knowing that you and your coworkers are going to be stuck up at the space station ( you are all astronauts) for the week following your trip south. So you decide to go out and find the beach that the hotel had told you was a great place to get some sun. Now as the three of you are walking through the heavy brush you encounter a native tribe that proceed to take you and both of your coworkers hostage. The three of you are them blindfolded and are told to sit down. After being seated in an equilateral triangle your captors remove all blindfolds and this is what you are told. The…

I'm working on a geocache and it's kicking my ass! Please help solve it. Here is all the info from the cache page... Space the Final Frontier… “These are the voyages of the Starship Enterprise. Its five year mission: To explore strange new worlds, to seek out new life and new civilizations; to boldly go where no man has gone before." On a mission to the Geocache Nebula, Captain Kirk and the crew of the USS Enterprise find out the ship’s supply of Dilithium Crystals is depleted. A safe flight home is in great jeopardy. After repeated distress calls to star base for more crystals, a location is sent. However, it is intercepted by a Romulan Star Empire “Bird of Prey” …

This is a tough one, but interesting. What very peculiar property do the following words have in common? cover, dust, left, transparent

Two problems... 1. What is i to the power i? (hint: it's a real number!) 2. Give a good approximation* for i^i^i^... (hint: exponentiation is right-associative. That means x^y^z means x^(y^z), not (x^y^z.) *for grading purposes, I will define a "good approximation" of complex number x to be a number, z, such that |x-z|<0.01

Heya. Well, since I'm new to this forum I thought that I could contribute by recommending a pretty good game available for Linux. The game has four categories; Logic, Calculation, Memory and Verbal. You can choose one of the categories or include all of them. If I'm not mistaken it should be included in the latest Gnome package, at least if you're installing a late version of Ubuntu. It should be available to most distributions though. http://live.gnome.org/gbrainy

Hey there. This is one I made for my friends (which they struggled with somewhat), so when I saw the puzzles section in these forums I thought I might as well share it... Q: Imagine a cube made of smaller cubes (like a Rubik's cube). Instead of measuring 3 by 3 by 3 however, this one measures 5 by 5 by 5. If you pick any two of these smaller cubes at random, what is the probability that their faces will be touching one another?

Your new mathematics-obsessed friend says to you, "I have two children. One is a boy born on Tuesday. What is the probability I have two boys?" The first thing you think to ask him is, "What the heck does Tuesday have to do with it?" "Everything!", he replies... So what is the probability?

This is a thread where each poster gives a riddle or an answer to a previous riddle. I'll start it off with a simple riddle. There are at least two answers that I know of. What can you put in a barrel and make it lighter (can't remove the air and add a lighter composition of air or add a container of gas.)?

there are N points on a paper. any three of points are not colinear. you draw lines from each point to all other points.lines can be drawn with three colors; red,yellow or blue. there will be obtained some triangles having colored edges. purpose is not to get a triangle, edges of which are drawn with the same color. what can be the value N at maximum?

This is an old one, so if you've seen it before, let the others think for a while before replying... You have nine dots on a paper, as seen below. Your task is to connect them with four straight lines without lifting the pencil: o o o o o o o o o .... and when you're done with that: Tell me how to do it with *one* straight line...

Have at it. (Moved this to a new thread so spammer could be banned)
