I have something called BETA smart little games on line for scrabble on my pc which I play from time to time in the evening if I lose interest in what's on tv. I always beat the computer because it doesn't play strategically, not using the triple/double word/letter squares when the opportunity arises. Annoyingly it's American English so our spelling is not recognised. Like others here have said, my pc will throw up strange words and random foreign words, but not more common foreign words that occur frequently. Shockingly it will use a very rude word or two on occasions!
