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 outcome of slots is accidental. The slots machine don’t remember wins or loses, they have no memory, so don’t try to overreach 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. Different slots have different payouts. So play slots with the higher 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 playing decide how much you can spend this day. Once that limit is reached, go do something else. You will not be a winner every time you play. 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. Find a machine that suits your bank-roll. Play dollar machines if you don’t have much money. Don't forget to cash out the credits you've accumulated. Sounds obvious, but a lot of people forget! Play the slots you know well.

To know what you are playing is necessary for you.
Only the correct amount of money should be inserted into a machine. Your credits should be cashed out before you leave the machine.
Slots shouldn't be a stress for you, just enjoy. Use money management. Increase your bets when you are winning, and decrease your bets when you are losing.

It seems that every type of activity has its own rules of etiquette, and playing the slots is no exception. Though slots are played by one person, still thinks which can and can’t be done during playing 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. 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. Tipping is another difficult issue for many slot players, and many people are unsure how much to tip the attendant that brings the winnings. If you win a jackpot you should tip the attendant with a tip equal to one half of one percent of the jackpot.

All slots work according to one and the same rule. You put coins or money in the slot machine and then pull the handle. Traditionally two main types of slots are distinguished: straight and progressive slots. The main principle of the straight slots is that you get paid according to the schedule listed on the machine itself. There are four other types inside of the straight slot group: multiplier, bonus multiplier, multiple payline and buy-a-pay slots. The Bonus Multiplier game offers a bonus if you make maximum bets. When playing multiple payline slots remember that the number of coins being bet determines the winning amount. The Buy-a-Pay slots are profitable only if you place maximum bets. Progressive slots are characterized by the big jackpot, which progressively gets larger and larger, as every coin is put in. The jackpot total is posted above the machine and can grow to enormous sums of money.
