As well as the games above, there's of course Facebook. There are a number of Facebook Scrabble apps for you to add to your profile. If you like word games and aren't too bothered about the prize element, then this is probably the best place to start.
For those of you with iPhones or iPads, then the official Scrabble App is also available for download. There's also Boggle and plenty more word games such as Hangman, Crosswords, Word Search and many more.
Online word game fans might also want to take a look at Puzzler. They have a number of prize draws where to enter you need to complete a puzzle.
