The game is...
Click to read the rest of this entry...- you compete against some other people
- each of you guess one number from [0, 100]
- compute 2/3rd's of the average of the guessed numbers
- the winner is whoever is closest
(0.66666) x ([7 + 28 + 53 + 77] / 4) = 27.5
Therefore, whoever guessed 28 wins!!
Physics Games
Nov 10, 2009
Need to waste some time?
This site www.physicsgames.net has a crapload of games that involve concepts like gravity, projectiles, constructions, "destructions", etc.
So far, I've played Splitter, Superstacker, MagicPen 1 & 2, Top Figures, Insurgo, Demolition City 1 & 2, and 99 Bricks, among others. Of course the site didn't make all these games, but the companies who do, let webmasters host them on their own site with certain restrictions.
My favorite is Cuber which is created by King.com :-D

How to solve the sudokube
Oct 26, 2009
The Sudoku Cube is a ripoff of the Rubik's Cube, where each face has the numbers 1-9 instead of colours. The goal:

Hey guys, there is this game called "Tower Stack" or "Tower Bricks" or "Tower Blocks" (among other names) and you can play it on Facebook, or MindJolt Games, or Brothersoft Games (etc).
Here is a screenshot to show what I am talking about:
What you have to do is:

What you have to do is:
- - build tower as tall as possible
- - blocks swing at top and you click mouse to drop them
- - block will fall after you click and it MUST land on top of the block that you dropped previously (otherwise you lose a "life" - you have 3 "lives")
- - if you drop PERFECTLY on top, you get bonus points
- - as the tower gets bigger, it starts to shake back and forth making it harder to drop the blocks on top
World of Warcraft - Negative gold problem
Sep 12, 2009
There is a flaw in World of Warcrafts statistics for "Total gold acquired". A couple years ago, players discovered that the most a character can hold is 2^31 (or 2147483648) copper pieces of currency. This is what is known as the "gold cap" in World of Warcraft. A single character cannot hold more gold than this in his backpack, otherwise an error is reported.
How to play STRIMKO

I thought it would be fun to create a video on "How to play strimko." It's just like Sudoku but more fun!! Hopefully the creators over at strimko.com don't mind me posting it on Youtube ^_^

Cool game - 20 questions - and how it works
Sep 2, 2009
Twenty Questions is a popular game which encourages deductive reasoning. Usually, one person is chosen to be the answerer. That person chooses a subject but does not reveal this to the others. All other players are questioners. They each take turns asking a question which can be answered with a simple "Yes" or "No". Lying is not allowed, as it would ruin the game. If a questioner guesses the correct answer, that questioner wins and becomes the answerer for the next round. If 20 questions are asked without a correct guess, then the answerer has stumped the questioners and gets to be the answerer for another round.

Checkmate! Tough Dice Game
Aug 25, 2009The impossible (yet so simple) dice game.
Play the game:
Instructions:
- Press the "Roll dice!" button to start.
- Try and determine how many moves there are until checkmate.
- Press the "Display Answer!" button to see if you are right.
- Once you have figured it out, don't spoil the fun for others!
Background:
This game is based on the "Petals Around the Rose" dice game. Both games are easy in the sense that once you know the "secret", you can easily determine the answer in seconds. After hearing of this game, I was able to figure out the secret immediately. Just remember, as in "Petals Around the Rose", the name of the game is important. Note however, you do not actually need to know anything about chess to figure out the secret.Petals Around the Rose - Dice Game
Aug 24, 2009Play the game here:
Instructions:
- Press the "Roll dice!" button to start.
- Try and determine how many petals are around the rose.
- Press the "Display Answer!" button to see if you are right.

Strimko is a brand new logic puzzle with numbers, just like Suduko. It is based on Latin squares described by Leonhard Euler in the 18th century.
The rules are simple: each row and column of an n x n grid must contain the numbers 1, 2, ..., n exactly once (just like in Sudoku ), and each "stream" (connected path in the grid) must also contain the numbers 1, 2, ..., n exactly once.
Strimko is created and developed by The Grabarchuk Family. It's basically a generalization of Sudoku as Sudoku can be thought of as having 9 streams.
You can play the addicting game at their website: strimko.com
Educational games - Planarity.net
Aug 12, 2009
We had a math camp at University and needed something educational for the elementary school kids. We chose the topic graph theory and decided to teach them about planar graphs. It turns out thathttp://www.planarity.net has this great flash game that you can play where you have to arrange the vertices such that no edges overlap. The kids sure had fun with it. It was created by John Tantalo, a CS undergrad at Case Western Reserve University.
Another task we had on paper was for the kids to design an air flight pathway between airports, where the airports are fixed 'vertices', and the flight paths ('edges') can't overlap to avoid crashes.
