Nashville is a late-era 6 card game - it came out in 1978, with only one more 6 card to arrive after before Bally closed their production down in 1980.
Nashville has all the features of Ticker Tape, but adds rollover buttons to achieve super lines and corner scoring on all 6 cards simultaneously, the magic number, which, when hit, will double all scores on each card, and the lovely red diagonals, which will allow for 8 additional scoring lines per card.
I've never played a Nashville, and look forward to playing it at the show in October!
