There are websites that donate 20 grains of rice to the U N World Food Program everytime a player selects the meaning for a word. This computer vocabulary game began ,when John Breen wanted to help his son prepare for the SAT.
The site is paid for with advertising income. 4 billion grains have already been won. Thats enough to feed 200,000 people for one day.
