update: removed 2 stars. Can no longer get coins by watching ads. Almost impossible to get decent letters. Enjoy the game. Not bothered by the ads. Catfishing men can be easily blocked. My only complaint is that there are times when the game ends while I still have tiles that can be played. I've lost games when I still had another play and would have won, plus raising my avg score. This is frustrating. The game should continue till there are no more plays for either player.
