As you know there are different types of slot machines. And do you know that there are even types of slot palyers.
The first type is a persistent player.
These players are sure that the machine is already ready to pay out, they just have to wait for a little. Any second now the slot machine will roll over and all the coins will be flying out and you will be rich.
Players become so persistent if they have already spent a lot of money for this slot and haven’t got anything or if they have found a slot machine that haven’t paid for a long period of time. They believe that a big win is sure to happen right now. The rush is that if they leave after depositing so much money in the machine it will erupt and the payouts will be often and large. Makes sense if you have lost 0. 00 and have yet to win. The machine must pay.

You can be sure that slot machines are designed to be honest. What you can really doubt is the honesty of some manufactures.
In the old days, slot machines worked mechanically, with independent wheels spinning until they each stopped randomly. Modern slot machines differ form the old ones greatly. Now the integral part of any slot machine is a chip, which is programmed to select numbers randomly. The numbers the computer selects correspond to the symbols that appear on the slot machine’s screen. The computer code that generates the random numbers is responsible for whether the machine is “loose” or “tight,” so gaming inspectors look at the machine’s code to make sure that a slot machine doesn’t cheat. That is, inspectors make sure that the machine pays off at the legal rate or better.
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. Inspectors look at brands of machines and their chips before they are installed in casinos, but they can’t inspect each machine. In the case of the approval of the brand the manufactures can produce the slot machines, even change them if it doesn’t go out legal bounds. Some dishonest manufactures use the right to produce machines, but use a different chip, which is programmed to pay less or not so often.
In one of the casinos the chip was programmed in such a way that royal flushes would never come out. Similarly, Universal Distributing Company was caught programming machines to show a “near miss” of a jackpot. The player would never hit a jackpot but keep on playing maximum bets. If you think you’re playing a machine that is not honest, you can complain. In the case if the complaint the inspectors will visir the casino and check whether the machines have a legal chip. Manufacturers that cheat are fined or they can lose their license.
