Here's a new vocabulary game online, and for each word you get right, they donate 20 grains of rice through the UN to help end world hunger. It's really great to get your brain working, especially in the morning!
My best level is 32, and I've so far donated 4200 grains of rice
I don't know how many are in a bag, but I know it's a lot lol! I just keep it open and when I'm bored I play it, and it makes me smarter for a great cause!
Here's the web site:
