Freerice is an ad-supported, free-to-play website and mobile application that allows players to donate rice to families in need by playing a multiple-choice quiz game. For every question the user answers correctly, 10 grains of rice are donated via the World Food Programme.
The website went live on October 7, 2007 with 830 grains of rice donated on its first day. The site was created by John Breen, a computer programmer, to help his son study for the SAT exam. The second word in its name was originally capitalized as «FreeRice.» On November 20, 2007, the WFP launched a campaign to «feed a child for Thanksgiving,» encouraging internet users «to take time out from traditionally the busiest online shopping period of the year and help the hungry» by playing the game. For a brief while, the amount of rice donated per correct answer was increased to 20 grains, though this was reduced to 10 grains of rice per answer within a few months.
