Gayle: I only go to river boats in Indiana. They always want you to use their comp cards when playing slots. But, the odd thing
about using them is if I insert the card and it says 'welcome' then I get a good amount of
play for my money. But, about half the time it will say re-insert card and there is no good plays. Could the card control the slots ?

I have stopped using a card and have done a lot better. Bob.

Bob: The program that calculates your card points is completely separate from the RNG computer chip in a slot, therefore one does not have anything to do with the other. It only seems that way.
Often, I have to re-insert my slot cards a couple of times until I get the 'Hello Gayle' go ahead signal.
If you are constantly having problems,I would ask for a new card or some help from a slot host Gayle.
