Nice! What dictionary did you use? Do you know if it's the same one that LetterPress uses?

I've been thinking about coding a player for LetterPress. Longest word mixed in with some endgame logic would actually probably do fairly well against most players, but it'd be interesting to see what other strategies would come into play.

I was cheeky and pulled the dictionary out of Letterpress. Once I've cleaned up the code I will push it to Github.

And if they don't? They'll probably disqualify you as a potential employer for asking such a question. Just doesn't seem like anyone wins from this.
