Why is it so hard to complete without buying?

I'm at level 1184 and it's impossible to get through some of these challenges without purchasing. They shouldn't be so impossible that you have to purchase or use most of your power ups and gold bars to get through. Just wondering....

It only gets harder I'm on 3495 and some of these levels I've spent days trying to pass them starting to get fed up with this game 😡
