"Free Rice lets users answer quiz questions and have the opportunity to donate rice to those in need. For every right answer on the website, the company donates one grain of rice. Free Rice creates an incentive for users to stay on their website for long stretches, all in the name of a good cause. The quiz questions can be set to vocabulary, math or science. Users can also log in and track their progress. This is an interesting way of bringing advertisers and users together for a good cause. &amp;lt;b&amp;gt;Implications&amp;lt;/b&amp;gt; - Youth consumers are eager to connect to the world and make a positive impact. Free Rice leverages gamification to attract both users and advertisers to its products. Companies should consider how they can give incentives through gaming processes."^^<http://www.w3.org/2001/XMLSchema#string>
