Greedy app developers just want money!! Too many ads and to be able to buy powerups during a level with in game coins it forces you to pay real money to use the powerup or you have to give up the level. I spent money on five cards then watched a video for 3 more and when I still couldn't pass the level I tried to buy a joker to remove the last card and it wouldn't let me without purchasing some kind of powerups pack I had to give up after using most of my coins. So stupid. Greedy app developers!
