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.
The players of this type believe that very soon there will be a period when the machine begins to pay. Any second now the slot machine will roll over and all the coins will be flying out and you will be rich.
The player has either seen a person playing a slots game for a while with no payouts or alternatively they have been depositing funds into a slots game and haven’t yet seen any payouts. They believe that a big win is sure to happen right now. 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 can’t but paying.
Many years ago in the case of the payout players touch the coins to check whether he coins were hot or cold. 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. But in reality any machine has numerous lights which heat the coins.
The chaser.
The player believes the slot machine is not one of those machines that never pay. One can feel the atmosphere of comfort and trust between the machine and the player.

Slots Rules: Understanding the rules of the game is always important, no matter what game you are playing. With slots the rules are very simple: Read the payout chart, insert coins, push button, (or pull handle), insert more coins. If you hear bells ringing and see lights flashing it means that you win. Of course you can win much, but never bet or spend more than you can afford.
Rules for playing Slots
Only slots have so simple rules. In fact it is so because there are no rules at all. The principle of the game is the following: the player inserts coins, pulls the handle and then checks the combination of symbols on the lines. The mission of the game is to match preselected symbols on the pay line, (or paylines, depending on the machine being played, there can be up to 5 pay lines on some machines), to earn credits. Slot machines can be found in many denominations from 5 cents to being the most popular, although there are also machines that accept 0 tokens.
It is a popular game for beginners because it is just them against the machine. They don't have to worry about rules and regulations, or being laughed at by the other players for making a bad play, all they have to do is try to hit the jackpot by matching the highest paying symbols on one of the pay lines.

The USA
The United States state governments regulate the availability of slot machines. There are a lot of states that have established gaming control boards to regulate the possession and use of slot machines. The only state that has no significant restrictions against slot machines is Nevada. In New Jersey only hotel casinos operated in Atlantic City are allowed to have slot machines. There are states that allow slot machines only on licensed riverboats or permanently-anchored barges. In Delaware there are slot machines only at three horse tracks. They are regulated by the state lottery commission.

Native American Casinos
There are no slot machines in Native American casinos located in reservations. But when the tribe first reaches a pact with the state in which it is located it is permitted. A pact entitles the state to receive a fraction of the gross revenue from slot machines.

Slot Machine Classes
No federal law governs slot machines. Their classifications may vary from state to state. Some states have restrictions on the type of slot machines that can be used in a casino or other gaming area. "Class III" (or "traditional") slot machines operate independently from a centralized computer system. The possibility that a player wing any payout is the same with every play. You can find Class III slots in Nevada or Atlantic City more frequently. "Vegas-style slots" is another name for them.
A centralized computer system is connected to "Class II" slot machines ("video lottery terminals" or "VLTs"). The outcome of each wager is determined by it. The chance of winning a series of limited prizes is equal for each machine. There is a fee for each Class III game that the casino has to pay to the state. Class II games are not so tightly regulated by the state.

Class II Game Characteristics
The player is playing against other players. Their competition is for a common prize. One player always wins the game. The game stops when the winner appears. A given set has a certain number of wins and losses. Once a certain combination has occurred it cannot occur again until a new batch is initiated. The games are dependant on each other. The player is an active participant of the game. The announced numbers belong to the same set of numbers for all players.

Characteristics Of Class III Games
The player is playing against the house. There is no connection between the previous and the next games. There can be any possible outcome in any game.

Clubs Of Slot Players
In American casinos there are "slot clubs" the membership of wich is free. They offer to return a small fraction of the amount of money that is bet in the form of comps. A member of such club should use cards to insert into the slot machines. The differences in the maximum theoretical returns can be significant thanks to comps or "cash back" from these clubs.

Australia
Queen of the Nile is very popular in Australia. Slot machines in Australia are officially termed Gaming Machines. In Australian-style gaming machines video displays are used to simulate physical reels. There are five of them in most cases. State governments regulate the use of gaming machines in Australia.
Not only casinos but also pubs and clubs in some states have Gaming machines. This style of gambling was legalized first in New South Wales. In 1956 they became legal in all registered clubs in the state.
In Western Australia only particular forms of gaming machine are used.

Britain
Fruit machines, one-armed bandits and AWP are the names for slot machines in Britain. Pubs, clubs, arcades, and some take-away food shops have fruit machines. There can be 3, 4 or 6 reels with around 16 or 24 fruit symbols printed around them. These reels should be spun. If certain combinations of fruit appear, winnings are paid from the machine. These machines and slot machines seen in casinos and elsewhere around the world are very similar. But there are some extra features. However, the jackpots from these fruit machines are strictly limited. Fruit machines in the UK also almost universally have the following features. A player is given the opportunity to hold one or more reels before spinning. The chance of winning can sometimes be increased. A finite number nudges following a spin can be also given to a player. The term nudge is used to denote a single-step rotation of a reel of the player's choice.
The type and the location of the machine influences the maximum payout for an individual game. Private members' clubs are allowed "club machines". They have higher jackpots and are allowed to charge more per game.
These machines and American slot machines operate differently. The probability of getting the jackpot in each game is independent of any other game.
The AWP fruit machine is played in Europe and in countries such as the Czech Republic, Russia, and Ukraine.

Slots In Japan
Pachisuro is the name for Japanese slot machines. They are a descendant of the traditional Japanese pachinko game. Slot machines are a fairly new phenomenon. Pachinko parlors and the adult sections of amusement arcades, known as game centers have them.
IC chips are used to regulate the machines. There are six different levels changing the odds of a "777". Despite the many varieties of the machines, there are certain rules and regulations.

There is a man who managed to cheat 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. Upon his release, he continued to work on the problem and to devise a better way to cheat the new 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. In some way he managed to fool the manufacture who showed him the inner construction of a slot machine. It was enough for Tommy. His new inventions was a light want that blinded the sensor of the slot machine and as a result got winnings. Carmichael marketed these wands to other slot cheats, making as much as ,000 a day. Now he could afford the most expensive cars and several houses.
But good thing will end one day. Tommy was caught using his invention in one of the casinos. While charges from that incident were later dropped, he was caught under similar circumstances in Laughlin and later Atlantic City. By that time the police already have all necessary clues to prove that Tommy was guilty. He got three years’ probation and lost everything that he had bought before. He has been banned from entering any casino.
