Most of the tiles go blank after playing one game. I'd suggest not using the "match me" feature to play word game with strangers unless you want to receive stalker like messages from angry men who are expecting to do anything BUT play the word game(luckily I was matched with a few women who never msgd me and played as i assumed we would) It's frustrating that the tiles are rarely containing fully printed letters or are blank and if you play the word puzzle it starts to freeze up and stops.
