I was there in December 2017 in Bethlehem, PA. Most of the games are Bob's own versions of the TV formats, I'm guessing because Bob doesn't own the rights to the shows. For instance, Card Sharks had four contestants get a row of cards on the screen of about 9 cards and each contestant goes through their entire row. The one that called the most correctly higher/lower won the game.
Seems like depending on the location of the show will determine how much money is given out. I saw from pictures online that the grand prize winner in Staten Island won $650. I believe the grand prize winner in Bethlehem won $2,500, plus every winner got a casino card to gamble equal to the amount of cash won.
