It's Scrabble. Seems to be stable and everything. Nothing real wrong with it that I can find yet. There are a few customizable rules. If you're a fan of Scrabble, go for it.
If you don't know what Scrabble is, it's a board game about spelling words and scoring the most points for the best words. Games on here that you may be more familiar with such as Bookworm, or DS titles such as Word Jong, were definitely inspired by the classic Scrabble. It's a bit like a crossword puzzle that you build yourself, without the clues.
I've been a lifelong fan of Scrabble and having it here on the computer without having to worry about tiles everywhere or getting out the old board is pretty nice, and I have an AI opponent to test myself against.
