Chuck - I don't understand why you would call the Gaming Comm, they will do nothing, just because you didn't win what you thought you would doesn't mean a darn thing, the slot machine just does what the random generator tells it to do and you just didn't get in sink with the generator.
Do you think the casino changed the inside parts ? You would be wrong here, they wouldn't take a chance as it is against gaming rules to change the comperter chips without removing the machine from play.
But lots of luck.
