You can still expect that higher denomination slots pay back better, but you don’t have as much insight as to how each casino breaks down payback denomination. Pennsylvania is different from some markets, such as Connecticut, in that payback isn’t reported by denomination, but just as an overall average.
As part of my project to analyze trends in slot machine payback, I turn my attention to Pennsylvania, home of quite a few casinos, including new options that have opened up in recent years.
