Is the black hole badge 'Tesla' still obtainable?

Hi akbhagat96,

Yes, I believe that badge should still be obtainable. The requirements for the Black Hole badges are secret though, but I can say you'll definitely need to work extra hard to obtain these rarest badges : )

Thank you Mr Evan for your quick reply! 

in order to get tesla you have to get 10,000,000 energy points. Hope this helped!
