Glitchy, not all features supported
The game used to work better than it does now. Letters disappear from the screen. You cant force slow playing opponents to play at least once per day because the nudge feature rarely now works. About a third of my opponents have not played in at least a day and I have no way to force play except to forfeit the game. The paid version of the game is frustrating to play.
Update: as of 6-8-17 they still have not fixed these problems
