Free rice
Basically the idea is to play a game to match words and there meanings. For each word you get right they donate 20 grains of rice through the United Nations to help end world hunger. Well, thats what they say anyway.
A total 355,559,540 grains of rice were donated yesterday.
You could try giving it a go, I was amazed at the number of words i had never seen before...0.o
