The United Nations World Food Program has a free, internet, vocabulary game called "Free Rice" which donates rice to the hungry. When you play the game, advertisements appear on the bottom of your screen. The money generated by these advertisements is then used to buy the rice. So by playing, you generate the money that pays for the rice donated to hungry people. Donations of rice will go to help the people affected by the devastating cyclone that hit Myanmar.
