Game closes during game so you have to start over! This would be a good game but the ads ruin it! AD after AD after AD, U SEE MORE ADS THAN PLAY TIME,if you love ads this app is for you. Once you hit high levels you can not complete levels without having to watch ad to finish the level plus during game play ads pop up sooooo intrusive and annoying deleteing this after i meet quota for points. Bottom line this game is one big fricken Ad!!!!!!!!!!!!!!!!!!not fun when ads are constant and annoying!
