What is your favorite free online word game?

I just discovered Merriam Webster's page and I love it because it is making me feel so smart!
They have vocab words, spelling games, item identification, and lots of other games.
Then they tell you how you "rank" according to other people in your age group who took the tests.

I have two sort of fun games on the kindle, but they don't make me feel very smart.

So I like this one better.

At the risk of making this sound like an advertisement, I log on to YouPlay. There's word games, puzzles, quizzes, etc, and you can either try to beat your own score or those of other players. I'm a fan of clueless crosswords but I'm
not very good at Sudoku.

Wordzup - I can lay in bed for almost an hour and not get bored with that game.
