seems like a simple game: you just match the word you see with a synonym.  But for every correct answer you get, the game gets harder.  When you choose an incorrect answer, the game gets easier.  The real challenge is trying to remember if the words are nouns, verbs or adjectives… it’s a lot harder than it seems!  This is a good way to practice for Part 4 of the Cambridge English: Advanced (CAE).

The game is run by the United Nations World Food Programme.  For every correct answer you get, you donate 10 grains of rice (an advertiser donates for you).  So practice your vocabulary and help end world hunger!
