There is no strategy that can really help you to win when playing slots Never believe if somebody says that he has an incredible winning strategy. The outcome of slots is accidental. The slots don’t have memory, that’s why it is not wise to try to outwit them. But there are some tips, which you can use as a basic strategy. 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. Before you start playing slots get acquainted with the payout schedule. Determine your losing limit for the day. Once that limit is reached, go do something else. When playing remember that you can win as well as lose. 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. When you're slumping, bet less. Play the slot machines that your bankroll can afford. If you have little money you’d better paly dollar machines. Cash out the credits you’ve won before leaving the slot machine you’ve been playing. Sounds obvious, but a lot of people forget! Try to play the slots or games you have played before.

You must know exactly the game you are playing.
Only the correct amount of money should be inserted into a machine. Cash your credits and only the leave the machine.
Just have fun. Slots should be fun, not stressful. You can increase your bets only 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. The first piece of slot machine etiquette is to determine deal or not to deal with particular 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? To do it you have to hang a coin cup over the handle of the slot machine. Placing the coin cup on the seat has the same meaning. 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. If you see any of these signals at a particular machine, be sure to respect the signal and move on to a free machine. If you find a card left by the previous player the second etiquette rule has to be applied. This is an extremely common occurrence, and just about every slot player has either found an abandoned card, left a card in a machine, or both. 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. Now smoking is allowed in most of the casinos. So if you smoke respect other players and place the ashtray as far from other players 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. If you win a jackpot you should tip the attendant with a tip equal to one half of one percent of the jackpot.
