Quoted from xyntec:
Question: how do the superjackpots of slimer work? If I hit him a couple of times I have to hit all the green shots before lighting the super, if I hit him once I only have to hit 1 green shot before lighting the super, and after I can do the same thing again, but how is this points wise? Would hitting all shots first be a bigger value super? And I think if I stack a couple of supers, I just get one and it stays lit after that so I can shoot it again, (not sure though, seems to vary) would be better if the super just gets more valuable?
It's lit when all the slime is cleared, regardless of whether that takes just one shot, or many more. They don't specifically increase the SJ
value, so points wise, you're better off cleaning it then collecting the SJ
As far as stacking SJs, some things award a "triple super" (e.g. Scoleri Bros.). I believe you can have up to a "sextuple super" on the stack at once, but you can only collect up to a triple off the stack per single shot. And if that is the case, I'd hate to think there's the possibility of wasting a SJ.
