freerice

When I was visiting my folks for the holidays, I heard my dad yelling at the computer from another room.

He's always yelling at the TV, so I thought for sure this could not be a good thing.

So I went to see what the problem was, and it turns out he was playing a vocab game at freerice.com

You gotta check it out. It's challenging, wildly addictive, and for every word you get correct, they donate 20 grains of rice to the United Nations.

Good fun. I've been playing it a lot, but come to think of it, I haven't been yelling at my computer like my dad...
