You're probably right jacksonwhite, but (I hate when the but comes out) my wife stopped using her casino points card several times at a couple casinos and she noticed better hits on those machines without using a card.
I've tried a few machines without my casino points card before and noticed the game seemed to play different, but I like my points to add up for free meals so I keep them in while playing.
I guess we could call it luck if machines act differently when we change our game play and notice more payouts.
What do you call it when this happens on nearly every machine? Luck, right?
Or, when all the machines start hitting at a certain time in the day. Is that luck too?
