The premise of the Free Rice website is to help end world hunger by donating grains of rice. Visitors to the website earn donations by correctly answering trivia questions based on subjects such as languages, geography, math and humanities.
Free Rice is a phenomenally successful Internet game that harnesses the power of the Internet and enables millions of people to fight against world hunger with a simple act. It is possible to sign up and log in to create, join and manage groups as well as track totals of rice earned and earn ranks on the leaderboards.
For every correct answer that a user submits, 10 grains of rice are donated to the United Nations Food Program. Users must click on the right answer from each selection to earn grains. If the answer is correct, users are challenged with a tougher question. If the answer is incorrect, an easier question is offered.
