Casinos in other parts of the country are struggling.
Las Vegas slot machine revenues are down 12 percent. Casinos in Atlantic City, N.J., have gone down 19 percent since last year.
In Pennsylvania, officials say that four of the five casinos that have been open more than a year are doing better than at this point last year.
