Better your own life by strengthening your vocabulary.
Better someone else's by providing them with a meal of free rice.
For each word you correctly define, this group will donate 10 grains of rice to the United Nations food relief efforts.
I maxed out at Vocab level 47, There are apparently 50 levels. You move up a level whenever you get 3 correct in-a-row.
Enjoy. Become obsessed with Free Rice.
