Free Rice is an educational quiz-type game. Players answer multiple choice questions. Immediate feedback is provided in the form of 20 grains of rice for correct answers. Incorrect answers are corrected and repeated later until answered correctly. This shows the player that they are learning something. The player can select among categories to be quizzed including vocabulary, grammar, art, chemistry, geography, languages and math.

In addition to seeing the growing amounts of "rice" earned for correct responses, players can take satisfaction in the fact that their earnings will be distributed to hungry people around the world. The sponsors of the Free Rice game aim to provide free education to everyone everywhere and to help end world hunger. Rice is paid for by sponsors shown on the page and distributed through UN world food program.

This is a very simple game but it is engaging and fun. The questions keep coming so it hard to stop. Seeing the amount of rice adding up for a good cause motivates the player to continue. Check out www.freerice.com and help feed the world.
