Come into this century
The word choices that are considered words in this app seem to be only the words provided. So you will be frustrated when you find that you could really stomp your opponent, then scrabble tells you that your have not created a scrabble word. The developers should figure out how this game along with players can add to the dictionary and play in the advance mode. In the days without electronics we could look up words in the dictionary. Developers maybe set up an app that provides the dictionary then the scrabble app can search it.
