Free Rice is an excellent idea — perfectly simple and infinitely rewarding for all sides. A friend who spends most evenings on a sweeps casino pointed it out, half-joking that it was the only other site where clicking something repeatedly could actually feel worthwhile. The premise is disarmingly straightforward: match words to their meanings, and for each correct answer, the UN donates 10 grains of rice to help end world hunger. So not only can you do a charitable act every day, you will also improve your vocabulary along the way. It’s all paid for by advertising on the site, and Bruji’s favourite company happens to be among the sponsors.
