There are at least two types of slot players.
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.
The player will play until the machine pays out. He must have found a machine that haven’t paid for a long period of time or he has inserted to many coins and has got nothing. They know the next big win, or any win is due to pay out. They can’t leave the machine because as soon as they do it will burst forth and pay out large sums. Makes sense if you have lost 0. 00 and have yet to win. The machine will pay any way.
Many years ago players have their own way of determining whether the machine has not paid out for a long period of time. They touch the coins to see whether they were cold or hot. If the coins where hot then the slot machine had not paid out in a while and to the chaser this was good as the machine was do. In fact the coins could be hot only because of the numerous lights that heated the coins.
The second type of slot players is a chaser.
The player believes the slot machine is not one of those machines that never pay. Players feel more comfortable and confident because they have been reinforced with a win and gain trust in the machine. One can feel the atmosphere of comfort and trust between the machine and the player.

Slots are one of the oldest casino entertainments. Throughout the years, designs and implementation of slot machines went from mechanical to electronic, and from electronic to digital, then from digital to purely software, but the principles are still the same: the slot machine has reels which spin and, if the pre-defined winning combination plays out, you win. Basically, you just put in the coins and wait to find out whether you won or not.
In fact all slot machines are the same. They only differ in some peculiarities: odds, payouts, payout percentage and symbols. There are so many varying designs around the classic slot machine that everyone could probably find their own ultimate preferred flavour.
Two most distinct types of slot machines are single line and multiline slots. In single line slots, the machine has just one line of reels, usually with 4 or 5 wheels, while in multiline there are a number of reel lines. Multi line slots are more difficult to understand because you win according to the winning combinations on the paylines, which can be formed in many ways. Sometimes you don't win anything at all, and sometimes multiple combinations award you with relatively big winning money. There are machines with paylines; that is, vertical lines along which a winning combination must occur, but some don’t have them, as the winning combination may come in diagonals, zigzags, strange curves and in other ways and fashions.
Jackpot is also a feature peculiar not for all slots. In jackpot games, the slot machines accumulate a fraction of every wagered bet into a virtual pot. As the players wager, the jackpot grows and grows, sometimes crossing hundreds of thousands of dollars. A certain winning combination hits the jackpot, and the lucky gambler collects everything that the ones before him left behind.
Slot machines are historically played with coins. Online casino slot machines are no exception to that rule, even though bets might differ slightly. Indeed, as well as with all small wager games, there are top bets - they're known as table limits in table games. Slots are the easiest casino games. They don’t require any decision on the player’s part.
Software slot machines (as well as the digital ones) are equipped with a random number generator which is what actually plays the game. That’s why slots are as fair as it is only possible.

The US
The United States state governments regulate the availability of slot machines. Many states have established gaming control boards to regulate the possession and use of slot machines. There are no significant restrictions against slot machines in Nevada. In New Jersey only hotel casinos operated in Atlantic City are allowed to have slot machines.

Casinos: Native American
Native American casinos located in reservations are not permitted to have slot machines. It becomes possible when the tribe first reaches a pact with the state in which it is located. The state is entitled to receive a fraction of the gross revenue from slot machines by the pact.

Slot Machine Classes
There is no federal law governing slot machines. There are different classifications of them. There are restrictions on the type of slot machines that can be used in a casino or other gaming area in some states. A centralized computer system operates "Class III" (or "traditional") slot machines. A player's chance of winning any payout is the same with every play. Class III slots are most often seen in Nevada or Atlantic City. "Vegas-style slots" is another name for them.
There is a connection between "Class II" slot machines ("video lottery terminals" or "VLTs") and a centralized computer system. The outcome of each wager is determined by it. Each machine has an equal chance of winning a series of limited prizes. There is a fee for each Class III game that the casino has to pay to the state. The regulations for Class II games are not so tight.

Class II Game Characteristics
The player is playing against other players. There is a common prize for which they are competing. One player always wins the game. The game continues until there is a winner. There is a certain number of wins and losses in a given set of wins. Once a certain combination has occurred it cannot occur again until a new batch is initiated. The games depend on one another. The player is an active participant of the game. The same set of numbers is played by all players.

Characteristics Of Class III Games
The opponents are the player and the house. There is no connection between the previous and the next games. The outcome of any game is unpredictable.

Slot Clubs
There is free memberships in "slot clubs" in many casinos of America. They return a small fraction of the amount of money that is bet in the form of comps (complimentary food, drinks, hotel rooms, or merchandise). The requirement of such clubs is the usage of cards for the slot machines. Comps or "cash back" from these clubs makes significant differences in the maximum theoretical returns.

Winnings are paid from the machine if certain combinations of fruit appear. Slot machines seen in casinos and elsewhere around the world are similar to these machines. These games have lots of extra features. However, the jackpots from these fruit machines are strictly limited. There are some features of fruit machines in the UK.

Meet the man who beat the slots.
Slot machines pay on a random basis, but what if you could improve the payout a little? Would you do it? Tommy Glenn Carmichael would and did.
A 53-years Tommy all his life tried to invent some kind of devices to cheat the slot machine. He was caught with one, called a top-bottom joint, and sentenced to prison. After the release Tommy began to invent new kinds of devices for cheating slot machines. The principle of his next invention was following: he inserted a guitar wire in the slot machine and it made the coins release from the hopper.
Later, as slot machines became computer based, he had to invent a new tool. Tommy found a manufacture who showed him the inside of a slot machine. It was enough for Tommy. Carmichael invented what he called a “light wand. ” The wand, built with a camera battery and a bright miniature light, was used to shine into the slot machine and blind a sensor, causing the hopper to pay out coins. Other gamblers liked his invention and he had a lot of customers, which allowed him to earn up to ,000 a day. With all this money he bought expensive cars, houses and what not.
Eventually, all good things come to an end. While using his devise Tommy was caught by the police. He was fined, but soon came back to the same business. By this time, authorities had tapped his phone and recorded conversations with other cheats who used his device. Three years’ probation and expropriation was the punishment. He has been banned from entering any casino.
