Computer uses non words!

How can one play a game against a computer when the computer cheats? I dont have the option to tell the computer its word is invalid! I tried several dictionaries to see if the word was valid and it seems its only valid in Italian! Scrabble rules-no foreign words allowed! I love to play scrabble, but its ridiculous when the computer cheats! Fix the dictionary! Update! Removed the app, refuse to play against a cheating computer.
This game has the ability to help one improve their vocabulary, but not when fake words are used by the opponent (computer) and no way to challenge!
