As with any game of pure chance, there is no real effective strategic system for winning at slots. You will probably, of course, encounter someone who claims to have developed thefool-proof' slots strategy system but please, ignore such advice. 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. Play slots with the payout above 95%. When playing slots you must always know the odds and probabilities of the slot you are playing. Make sure you know the payout schedule before you start pumping in your virtual coins. Before you start playing set for yourself a losing limit. Stop playing when you reach this losing limit. You will not be a winner every time you play. The machine will not feel bad if you spend a lot of money and don't get anything back. Try not to spend all of your time on a machine that isn't paying out. If the machine pays out good you’d better make higher bets. 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. Before leaving the casino don’t forget to cash out the credits. Sounds obvious, but a lot of people forget! Play the slots you know well.

As you know there are different types of slot machines. And do you know that there are even types of slot palyers.
Persistent player.
The players of this type believe that very soon there will be a period when the machine begins to pay. Just a second and the coins will be flying all over the casino!
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 at least any payout is due to happen. 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. But in reality any machine has numerous lights which heat the coins.
The second type of slot players is a chaser.
The player thinks that the machine he is going to play is not a machine that never pays. Players feel more comfortable and confident because they have been reinforced with a win and gain trust in the machine. 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. Even though playing the slots is primarily a solo activity, there are definite do's and don'ts when it comes to playing the slots. First of all decide whether to deal or not to deal with this very slot machine. 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? The most commonly accepted signal is to hang a coin cup over the handle of the slot machine. Another signal is to place the coin cup on the seat. Instead of the coin cup you can leave something of your belongings. For example, a jacket or a coat. But it will work in casinos where the cashless system is used. In your turn you should respect other players and never sit to a slot that is in play. The second etiquette rule concerns the card left by the previous player. It happens very often that a player leaves his card and walks away. The accepted way to deal with this situation is to place the player card on top of the slot machine where it can be easily seen and retrieved. Nowadays most casinos allow smoking while playing. Of course, others will hardly like it, so try to make as few inconveniences as possible. Tipping the attendant that brings you the winning is one more etiquette rule. There are a lot of questions about the sum of a tip. In the case of a jackpot tip him with 0,5% of your jackpot.

You can be sure that slot machines are designed to be honest. But there are some manufactures that design the slots in such a way that they can deceive players.
In the old days, slot machines worked mechanically, with independent wheels spinning until they each 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. The selected number determines the symbol which then comes out. 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. The machine has to pay out either to the legal rate or better. Of course the latter happens very seldom.
It is next to impossible to say whether the chip is programmed not in a right way because the machine is not supposed to pay out with every spin. Before the machines are installed in casinos they are examined by inspectors. But you must understand that inspectors can’t examine every machine. They examine the brands. 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.
For example, the Nevada Gaming Commission caught American Coin using chips that did not allow poker royal flushes. Or a chip that shows near misses of a jackpot. The player would never hit a jackpot but keep on playing maximum bets. Don’t keep silent if you come across such slot machine. Be sure that inspectors will examine this very machine and the casino itself to make sure everything is ok. Manufacturers that cheat are fined or they can lose their license.

There are many types of slot machine configurations but all work according to the same principles - put the money in the slots and pull the handle! Traditionally two main types of slots are distinguished: straight and progressive slots. If you play slots then you are paid in accordance with the payout schedule, which is always shown on the slot. There are four other types inside of the straight slot group: multiplier, bonus multiplier, multiple payline and buy-a-pay slots. When playing multiplier slots you should always bare in mind that the payoff is dependent on the number of coins being bet. The Bonus Multiplier game offers a bonus if you make maximum bets. The principle of multiple payline slots is that the number of enabled payline depends on the number of coins bet. The Buy-a-Pay slots are profitable only if you place maximum bets. The jackpot for Progressive slots is never the same as it grows higher with every coin put in the machine. The amount of the Progressive jackpot is always shown on the slot.
