Texas State Gambling Laws & For Profit Business

I have a business idea that would be similar to Chuck E Cheese but for Adults. The business concept would be a Luxury Bowling Alley w/ Restaurant, Bar, Grill, Arcade, and Lounge. The addition I would like to add is a Casino. Consumer could play traditional casino games i.e. slots, poker, black jack etc. They would purchase chips and tokens with money, but the pay out would be chips and tokens. When they cash in they would be give a card similar to a gift or debt card with the credit amount won. This could be used as currency all over the establishment to buy games of bowling, drinks from the bar, food from the restaurant, or merchandise from the gift shop. The credit would only be good in our establishment. Under the Texas State Gambling Code would this be legal? This is for due diligence.
