There is hardly any strategy that can be applied to 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 are casual, there is nothing that can influence the outcome of the game. The slots don’t have memory, that’s why it is not wise to try to outwit them. But it is wise to play with useful tips, which can really help you. It doesn’t mean that you will win a lot of money, but you will not lose so much. You should always be looking for the machines that have the highest payout. Try to find something above 95%. When playing slots you must always know the odds and probabilities of the slot you are playing. Before you start playing slots get acquainted with the payout schedule. Before playing decide how much you can spend this day. If you are more likely to exceed this limit you’d better give up the game. It is not wise to think that you will be a winner all the time. You will lose too. The machine will not feel bad if you spend a lot of money and don't get anything back. If you think that the machine you are playing will hardly pay anything out you’d better stop playing it. When things are going your way and you're on a lucky streak, take advantage of it and bet more. Make lower bets if you are slumping. Choose a slot according to your bankroll. Play dollar machines if you don’t have much money. Cash out the credits you’ve won before leaving the slot machine you’ve been playing. Sounds obvious, but a lot of people forget! Never make high bets if you play slots you have never played before.

Here is the list of the most amusing myths concerning slots.
You can spot a winning slot machine.
The only way you'll spot a winning slot machine is when the bells are ringing and the money is dropping. Slot machines use random numbergenerator and that's exactly that. Random.
Casinos place loose slots near the cashier, aisle ways, etc.
If this were true, it would be the only machines anyone would play. A casino mixes slots all over the casino floor. No one with any experience at playing slots would make a statement like this.
Count the number of symbols on the reels to determine your odds.
This is mathematically impossible, remember the RNG (random number generator) determines the stops. Thereare literally millions of combinations on a 3 reel slot machine, so there is no way of determining odds by the symbols on the reels alone.
Casinos can tighten or loosen slot machines from the back office.
In order to change how a slot willpay out is by changing the computer chip. No casino can just flip a switch.
A slot machine that has not been paying is due to hit.
Absolutely false. The RNG assures this. You have an equal chance of winning on a losing machine as you do on a machine that just paid out the jackpot.
Pulling the slot machine handle produces more wins than pressing the spin button and visa versa.
Again false. It makes no difference, as the computer only uses these as mechanisms to start the game. Only the computer determines a win or a loss and it has already determined if you are a winner or loser even before the first reel stops spinning.
Playing with hot coins improves your chances.
Once again, the computer determines a win or loss and the temperature of the machine or moneyirrelevant. Although it's funny that people still burn their fingers with lighters believing this works.
Casinos set slot machines to payback more on the weekends.
Wrong again. Your odds of winning are the same no matter if it's 4:00pm Monday, 8:00pm Saturday or 3:00am Wednesday. Casinos can not and do not do this.

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 have different odds (and of course payouts), different payoffs, different symbols and different exterior arrangement, but there's little difference under the hood. 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. It can happen that you win nothing during the game or that you win big in a short while. 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.
Another interesting variation of the slot machine is a jackpot. If the slot machine has a jackpot it means that a certain amount of each additional bet is added to the jackpot. So the jackpot becomes bigger and bigger with every bet. Jackpots can reach several hundreds of thousands dollars. There is only one winning combination that can bring the gambler the jackpot.
Slot machines are historically played with coins. Online casino slot machines are no exception to that rule, even though bets might differ slightly. Like regular slots they have betting limits, which can be even lower than in real casinos. Unlike the table games, slot machines don't involve any decision on the player's part and so aren't threatened by game management systems because of their fixed odds; the bet limits are more of a traditional thing than anything else.
Software slot machines (as well as the digital ones) are equipped with a random number generator which is what actually plays the game. This methodic allows very fair and precise balancing without actually hurting neither the players' interests nor the casino revenue.

You can be sure that slot machines are designed to be honest. However, in the past certain manufacturers have been caught using computer chips that cheat the customer.
The very first slot machines worked according to the following principle: the wheels spun and then each of them 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 selected number determines the symbol which then comes out. There is a computer code. It generates the random numbers and determines whether the slot machine is loose or tight. The gaming inspector will examine the machine to make sure it will not deceive the player. The machine has to pay out either to the legal rate or better. Of course the latter happens very seldom.
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. The machines have to be examined before people begin to play them. Of course it is very difficult to examine every single machine, that’s why inspectors examine only brands. Once inspectors approve a brand of machine, the manufacturers can make changes to individual machines as long as the changes fall within the legal bounds. Using their right to produce slot machines they insert different chips, which makes the machine pay less.
For example, the Nevada Gaming Commission caught American Coin using chips that did not allow poker royal flushes. Similarly, Universal Distributing Company was caught programming machines to show a “near miss” of a jackpot. The effect was two-fold: the machine didn’t pay off, and customers continued to play the machine, thinking that they were very close to a big jackpot. If you think you’re playing a machine that is not honest, you can complain. Inspectors will respond by pulling the slot machine’s chip and seeing if it is an approved chip. 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! According to the main slot classification there are two types of slots. They are straight slots and progressive slots. The main principle of the straight slots is that you get paid according to the schedule listed on the machine itself. Straight slots in their turn can be divided into 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 main principle of bonus multiplier slots is a bonus round, which becomes active if you play with 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.
