Quoted from Yoko2una:I was going to say that it's either from the Black Hole or possibly from getting past Warp 9.9. I know on the Warps I get EB at 3rd, Double Scoring at some number, and perhaps there was a 3rd award for cycling back to Warp 1. It doesn't happen a lot, so I don't recall.
you get back around to double scoring again.
it is a black hole mystery award, you also very rarely get extra ball from it. i think ive seen it happen like 3 times on my game in over a thousand plays hah.
