FreeRice is completely addicting. You get a vocabulary word and four choices (just like the word thing in Reader’s Digest). If you get the correct word, 10 grains of rice are donated. It automagically (which is NOT a word in the game) works with your level so it challenges you and you might learn something.
WARNING: This game may make you smarter. It may improve your speaking, writing, thinking, grades, job performance..
