Oh, please ... myths are nothing more than excuses for losing. And almost all slot machines are going to be losers. Even if the RNG is chip is programmed at 95% (very few are that high) ... you WILL lose money without a 'lucky' hit.
Just because the ticket cash-out is on a central computer, as well as the central connection for the player's card, that does NOT mean that the RNG is also connected.

The casino does not have to cheat to take your money. All they need to do is put in a bunch of machines that you have no way of knowing whether it is an 85% chip or a 99% chip, and let you sit there and lose your money. At least with a Video Poker machine, I can tell just by looking what the payback is ... and pick out a good machine, or leave.
