How to beat Level 512?

[MeinIdaho]

If anyone out there had insight on how to beat Level 512, please share.  I have been stuck there for several days without even coming close to beating it.  There must be a special power that would assist?  Anything you could share - I am all ears.  Thank you in advance.

Had to use almost all my flame swappers. Scrambling also helps. Star swapper with a hypercube helped me get 3 stars

Azait60, I wondered if scramblers was the solution, but haven't seen much opportunity to use flame swappers near the end. How many is "almost all"?  I currently have three. Do I need to stock up?   Thanks for offering advice! 
MeinIdaho- have you been able to complete this level yet? 
Thanks!

Definitely stock up and keep using 2 next to each other to get a strong explosion
