Quoted from abjr:I agree it continues with a mutiball but not all six, three are in play with my machine.
In L-1 this is what should happen:
If you played a "normal" game, the buy-in gives you a 4 ball multiball like the one you get when you lock 3 balls in the ring.
If you played a "super game", the buy-in continues the super game (the "game" started is usually number 4, destroy the dead world, but it can be any other "game" as well ).
I don't know about L-7, but it could be the same.
