Free Rice

It’s a pitty that not all charitable organizations can be as fun and educational as FREERICE. Freerice is a word game. For each correct answer, the site’s administrators donate 10 grains of rice to the UN World Food Program. If you don't think playing with words is that funny, you can also tell the game to give you questions about famous paintings, chemical symbols, world capitals and more. Besides being entertaining it made me feel good :) Perfect for a rainy day!
