Now you can improve your word power and help feed some of the world’s poorest people. Freerice.com contains an addictive little word game.

The game throws out a word from its immense dictionary - all you have to do is click on the answer that best defines the word in question. If you get it right, you get a harder word. If you’re wrong, you get a slightly easier one.

For each word you get right, the site donates 20 grains of rice to the United Nations World Food Programme. Doesn’t sound a lot, but you’ll be surprised how quickly those grains mount up as you take your brain to ever higher planes!

Try it today - but make sure you’ve got a bit of free time to spare because, as we say, you may be there longer than you think!
