Hello @Abdul15 You might have noticed that one of the game’s designer's has joined this community. Going by some of @LindQ comments I understand that all of the levels can be completed without using boosters and without the need to pay to play. Some of them are very difficult though.
I also understand that whilst all of the levels are tested before they are released, they also respond to player feedback.
The upshot of all this is that if you play all the levels as soon as they are released you are in some way being used a a tester yourself. If I were you playing at this level I would be tempted to wait until all of the kinks in the new levels had been identified and ironed out.
You might lose the kudos of completing the game before anyone else, but in the long run it would save you a lot of frustration.
