More problems than it's worth. You can only win by using "power ups". In order to get "power ups" you have to buy them with a credit card or spend a tremendous amount of time slowly winning them. Then the game takes the "power ups" away from you. They just dissappear and you have to start all over. This is just one of many "bugs" with this game. To make matters worse, tech support "policy" is to reply within 14 days. 14 days! 14 days for them to even respond to your chat!!! Don't bother.
