These games suppose to be free to play as long as you have friends to send you lives. But, you need to buy stuff to get you through the levels. Also, you don't have nowhere to go to have an option to buy what you want and there is no price listing of what the cost options are. They just tell you what you need when you are already in trouble while you are playing your level, and they offer to fix this for you at a price. Then often, there is another fix that is offered and at a higher price to still get you through that same level. You could end up putting a lot of money out. It sure isn't that way at the beginning of the game.
