Words With Friends

This Scrabble clone changes the classic board game from something you need to sit down and play with your grandparents, to an online experience where you can play several people simultaneously, and take your turn whenever you like. The new version tracks your performance, showing you your scores relative to other people, the longest words you've played, as well as your overall win-lose record. There is now also an in-built dictionary feature, so next time you gain points for a two-letter word you don't understand, you can find out what it actually means.
