You can be sure that slot machines are designed to be honest. However, in the past certain manufacturers have been caught using computer chips that cheat the customer.
The very first slot machines worked according to the following principle: the wheels spun and then each of them stopped randomly. Today’s slot machines are light years away from those lumbering machines of old. There is a chip inside of every slot machine, this chip is programmed to select numbers randomly. After selecting a number a corresponding symbol appear on the screen. There is a computer code. It generates the random numbers and determines whether the slot machine is loose or tight. The gaming inspector will examine the machine to make sure it will not deceive the player. The machine has to pay out either to the legal rate or better. Of course the latter happens very seldom.
Because slot machines don’t pay off with every spin, it’s difficult for customers to tell whether a slot machine’s chip has been programmed to pay off less often than is legally required. The machines have to be examined before people begin to play them. Of course it is very difficult to examine every single machine, that’s why inspectors examine only brands. If inspectors approve the brand, they can produce machines, and change them. But these changes must cover legal requirements. Using their right to produce slot machines they insert different chips, which makes the machine pay less.
There is an example when there was inserted an illegal tip which doesn’t allow royal flushes. Or a chip that shows near misses of a jackpot. The effect was two-fold: the machine didn’t pay off, and customers continued to play the machine, thinking that they were very close to a big jackpot. If you think that you have come across such a machine you have a right to complain. Inspectors will respond by pulling the slot machine’s chip and seeing if it is an approved chip. Manufacturers that cheat are fined or they can lose their license.
