Can't pause and switch to another app and come back. Crossword Jam has to restart from. the beginning. Can't play Pandora in the background, the ads cut it out every time a game finishes, then Pandora doesn't start up again and to restart Pandora, you have to leave Crossword Jam, which then has to start up again from the beginning. The game is not that good to go through all the aggravation. More time spent restarting apps than playing the very elementary game. Can't turn volum off on ads
