It seems blindingly obvious to me that getting rid of the bingo card would hurt sales. It doesn't matter what you replace it with, nothing is going to communicate "I have bingo cards" better than a picture of a bingo card. Here's a much more interesting question: Have you found the optimal bingo card? What if you ditched the blue circle, and just made the card bigger? What about the font/colors? Can you get a 1% increase in sales just by iterating your existing logo?
