These games were like the next generation slot machine back in their day. Slots were illegal but you could still gamble on bingo games. If you got '5 in a line' with the 'Double Double' or some other multiplying feature you could win 300+ games. That's 300 nickels, dimes, or quarters depending on the era and price of a card.
There are still a scant few clandestine DIXIELAND bingos being operated around here in some clubs that payout a quarter a credit. Just don't tell anyone.
Be warned though, it takes eleven quarters to light all six cards with all of the features. That's $2.75 for one game with five balls no fllippers and a SUPER sensitive tilt.
