Not too happy with my experience... I was hoping to see some instructions on what you're supposed to be doing but I had none, and for my first play I tried ZEN, but it was not accepted, and I can't find if there's an option to swap tiles, so I just quit the game. Why not follow an edition of one of the Scrabble dictionaries?
It's a nice touch to support multiple languages though and I enjoy the idea of a solo Scrabble video game, but because of the above issues I don't really see myself playing it again unless they're addressed in an update.
