Free Rice

Free Rice is a trivia game developed by John Breen. The free-to-play, ad-supported website donates the cash equivalent of 5 grains of rice for every question you answer correctly through the United Nations World Food Program. There are multiple trivia categories: global goals, geography, English, humanities, language learning, math, science, and newly „Coronavirus: know the facts“. Since its beginning in 2007, they have donated more than 202 billion grains of rice and millions of meals.
