I came across Free Rice during class (when I should have been paying attention) and I’m hooked. Each time you get a word definition right, 10 grains of rice is donated through the United Nations to help end world hunger.

Play and win free rice for the starving

How can playing a word game actually end world hunger? Well, every time you click on a word and get the definition right, a list of advertisers shows up on the bottom of the screen. The money generated by the ads used to buy the rice.

10 grains of rice a word probably doesn’t sound like much, but when you take a look at the total stats on the Free Rice site, it’s impressive.

So not only are you getting smarter, but you’re feeding people!
