I bet many of you have played the Word Power in Reader's Digest before. You know, they give you a word and four meanings to chose from. Sometimes they seem easy. Sometimes challenging. But you almost always come away from them knowing a little more.
Well, the same idea is at work for good over at Free Rice. You are given a word and four meanings (synonyms). For every correct answer you earn 20 grains of rice. Every time you answer correct, the words get tougher. Miss, and it backs up to an easier level. When you stop playing your "rice" goes to the United Nations fund for world hunger.
I played for about 30 minutes today, maximum level 40 and earned over 4,000 grains! So, if you are a vocabulary nut or you know you need to grow your vocabulary it's a great way to have some fun and help fill a need.
