It's not your usual internet game... and not your usual winning outcome.
Free rice is a vocabulary game that helps deliver rice to countries in need.

For each correct word chosen in the multiple choice game, sponsors donate twenty grains of rice to combat world hunger, through the world food programme.
So far, according to the site, the World Food Programme's total donations is almost 32 billion grains of rice.
