As with any game of pure chance, there is no real effective strategic system for winning at slots. Never believe if somebody says that he has an incredible winning strategy. The slots don’t have memory, that’s why it is not wise to try to outwit them. The strategy can be represented only by a number of tips. Try to play slot machines that have the highest payout. You want to find anything above 95%. Like other casino games it is very important to know the odds and probabilities of the game you are playing, the same thing with slots. There is a payout table for each slot, so make sure you read it before inserting coins. Determine your losing limit for the day. Once that limit is reached, go do something else. You will not be a winner every time you play. Don’t think that machine will feel guilty if you insert a lot of coins and get nothing back. Give up the machine that isn’t paying out and is not going to. Don’t be afraid of making higher bets if you are on a lucky streak with this very machine. Make lower bets if you are slumping. Choose a slot according to your bankroll. If you have little money you’d better paly dollar machines. Don't forget to cash out the credits you've accumulated. It may seem strange but some gamblers forget to do it. Never make high bets if you play slots you have never played before.

There exist at least two types of slot players.
Persistent player.
These players are sure that the machine is already ready to pay out, they just have to wait for a little. The machine can begin paying in any second.
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. 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 will pay any way.
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. A sense of comfort exists between the slot machine and the player.

Every casino game has its own rules, features and of course etiquette. Slots are not an exception here. Though slots are played by one person, still thinks which can and can’t be done during playing slots. To decide whether to deal or not to deal with this slot machine is of great importance. Imagine you leave the slot and go to the bar or to the restroom and you want to come back in a few minute and continue playing. How can you let other people know that the slot machine is in play? To do it you have to hang a coin cup over the handle of the slot machine. Another signal is to place the coin cup on the seat. In casinos that use a cashless system, a personal item such as a jacket can be placed on the seat instead. In your turn if you see somebody’s belongings or a coin cup never sit to this slot machine. You can sit to any other slot machine. The second etiquette rule concerns the card left by the previous player. Sometimes you can find in the slot machine a card left by the previous player. If you face a situation like this you have to put the card on the top of the slot machine where it can be easily seen and found. While most casinos do allow smoking, it is important for those who smoke to be courteous to others, and to position the ashtray in a manner which inconveniences other players the least. The last etiquette rule is tipping a person, who brings you the winning. In the case of a jackpot tip him with 0,5% of your jackpot.

United States
In the United States the availability of slot machines is highly regulated by state governments. There are a lot of states that 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. In some states slot machines are allowed only on licensed riverboats or permanently-anchored barges. Only three horse tracks are allowed to have slot machines in Delaware. There is State lottery commission to regulate them.

Native American Casinos
Slot machines are forbidden 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. Typically, a pact entitles the state to receive a fraction of the gross revenue from slot machines.

Slot Machine Classes
There is no federal law governing slot machines. There are different classifications of them. There are states where the usage of slot machines in a casino or other gaming area is restricted. The operation of "Class III" (or "traditional") slot machines is fulfilled from a centralized computer system. The chance of winning any payout is the same with every play. Nevada or Atlantic City have more Class III slots than any other state. They are also called "Vegas-style slots".
There are "Class II" slot machines ("video lottery terminals" or "VLTs") which are connected to a centralized computer system. The determination of the outcome of each wager is fulfilled 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. The state doesn't regulate Class II games so tightly.

Class II Game Characteristics
The player is playing not against the casino but against other players. Their competition is for a common prize. There is always someone who wins. The game is continued until someone wins. In a given set there is a certain number of wins and losses. The combimation that has already occurred cannot occur again until a new batch is initiated. The games are dependant on each other. The player must be an active participant. There is 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. The outcome of any game is unpredictable.

Slot Clubs
Many American casinos offer free memberships in "slot clubs". A small fraction of the amount of money that is bet is returned in the form of comps. These clubs require that players 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 (manufactured by Aristocrat) is one of the most popular Australian poker machine games. Slot machines in Australia are officially termed Gaming Machines. Physical reels are stimulated by video displays in Australian-style gaming machines. There are usually five of them. The use of gaming machines in Australia is regulated by the laws.

Britain
The terms fruit machines, one-armed bandits and AWP are used to denote slot machines in Britain. Fruit machines can be met in pubs, clubs, arcades, and some take-away food shops. There can be 3, 4 or 6 reels with around 16 or 24 fruit symbols printed around them. These reels are spun. Winnings are paid from the machine if certain combinations of fruit appear. These machines and slot machines seen in casinos and elsewhere around the world are very similar. But some extra features can be found. However, the jackpots from these fruit machines are strictly limited. The UK fruit machines have some features. A player is given the opportunity to hold one or more reels before spinning. It sometimes increases the chance of winning. A finite number nudges following a spin is given to a player. A single-step rotation of a reel of the player's choice is a called a nudge.
The type and the location of the machine influences the maximum payout for an individual game. Private members' clubs are allowed "club machines". Their jackpots are higher and they 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 popular across Europe and in countries such as the Czech Republic, Russia, and Ukraine.

Japanese Slots

Have you ever met a man who has 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.
Carmichael, now 53, had a long history of inventing devices to cheat slot machines. His first device was a kind of a top-button joint. By the way, for this device he was sent to prison. Then he was released, but continued to work at inventing devices for cheating a slot. His next invention was a slider, a guitar wire. He inserted it into the machine, which released coins form the hopper.
When the slots were computerized he needed a new tool. He fooled a manufacturer into believing he was a customer and showing him the inside of a slot machine. It was enough to learn everything that he wanted. 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. With all this money he bought expensive cars, houses and what not.
But good thing will end one day. While using his devise Tommy was caught by the police. 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.
