I'm sorry you're having trouble with the game @Bamaw1965! Some levels are indeed extremely hard. Especially if you don't have enough boosters. My advice to you would be to join an active fantastic five team. It can be a great help!
Think a lot of people would disagree with you on this and quite a few in the community. The pre released levels are only available on the win 10 app on a PC / Computer and many people in the community are on the last level
