I came across this site via the Instant Messenger status of one of my pals which promises to donate ten grains of rice for every word you get right in their vocabulary game. The game works like this, a word is presented to you with four probable synonyms. You are given the task of choosing one that best relates to the current word. If you answer correctly, ten grains of rice are donated through the United Nations to end World Hunger and as you play, you also get to see a nifty bowl beside with some graphical grains in it!

Fun apart, this seems to be a noble initiative to end world hunger, and all you have to do is play the game! The game is quite interesting I tell you and you get to build your vocabulary too. If you select a wrong option, you are told the right option and are allowed to play again. You can learn a lot of new words this way and I also read that the system automatically guesses your vocabulary level and adjusts accordingly! Cool! And as you keep guessing the right answers, ten grains of rice are donated for each correct guess!
I played for a few rounds and had some 100 grains in my basket when I was curious as to how this was being funded. I noticed ads at the bottom from some biggies like American Express and just checked the FAQs and found that the rice was sponsored by the ads! Way to go guys, A noble initiative for a noble cause!
