I first heard about this game when I was in 4th grade.Basically you answer easy,medium,or hard questions about subjects.For each one you get right you donate 10 grains of rice to the World food Program.So far they have donated 91,864,527,800 since October 7th,2007.I think its fun but you should give it a try ^^.

I've done this before, pretty cool. I managed to rack up like 2500 grains of rice on a boring day once, lol.

170 so far xD
