FreeRice is not sitting on a pile of rice―you are earning it 10 grains at a time. Here is how it works. When you play the game, advertisements appear on the bottom of your screen. The money generated by these advertisements is then used to buy the rice. So by playing, you generate the money that pays for the rice donated to hungry people.In other words, the more words you get correct, the more you feed the hungry. It is a pretty fun game and is especially helpful in preparing students for standardized tests like the SAT.
