Alt-L (on the top box) to link the machine and all opened slaves at the same time, helped me out with Party Bingo, i was unsure why it didn't work but now does, it used to i am sure when i played before, so something i likely did lol, thanks for the help there.
I still am partial to the £15 games (when i played for real probably the first time) Spiker the Biker and such Barcrests, but hating the recent £100 cashgrabs now.
