Beware. This is one of the worst, most intrusive apps I have ever seen. The ads are hard to stop or get rid of and very intrusive. It is a battery hog. I make sure to close it after every play. I only accept games from my wife. Many common English words are inexplicably missing. This is especially true of words that were in common use 100-150 years ago but not now. Shakespeare would be sad, but it seems to be the only alternative at this time. I would gladly pay for a version that was ad free.
