I can't remember these multiballs and can't really say I can differentiate multiball between machines as you're basically trying to keep the balls in play for as long as you can, with the side plots of trying for jackpots etc. So with my limited games I play at home I actually like the T2 multiball for one reason and thats to hit the Super Jackpot. I can do it with ease if I've trapped the other balls on my machine but Jeez its tricky letting go of a flipper to shoot the gun when there's balls flying around.
The other MB's sound great though (and difficult)
BTW I hated Black Hole coz it f*&ked with my head how the lower playfield flippers were operated in reverse. I'm not good with abstract concepts. But it didn't stop me from putting in heaps of coins so I could get that MB and spew when I get all unco-ordinated!!
