Gday Tony .
I have a Williams '68 pinnie called Lady Luck . Its a 2 player game but is cleverly designed for a multiplayer EM because the theme is Blackjack . Each ball you are trying to beat the dealer . The dealers card score is revealed at the end of each ball . Unfortunately the plastics and artwork on the cab don't go with the theme but the backglass and playfield art do.
Its tricky to play because on the one hand you are trying to get the highest score (same as any game) but you are also trying not to bust (the hard part) .
Its one of only 4 pins ever designed with a Blackjack theme, far as I know.
My resto thread is here . I think its a pretty darn good game
