Here is the list of the most amusing myths concerning slots.
You can spot a winning slot machine.
The only way one can say that theslot machine is a winning one is only to catch this moment, when the machine pays out. 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.
It is a rude mistake. RNG decides when the machine will stop and there are thousands of combination available on a 3 reel slot machine.
Casinos can tighten or loosen slot machines from the back office.
It is not as simple as that. The casino can’t just change the chip of the slot machine. It is illegal and it has to be permitted by the commission.
A slot machine that has not been paying is due to hit.
It is not so. With every game the chances of winning are the same.
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.
It is false. Nothing can affect the outcome, the machine doesn’t care and doesn’t know whether your coins are cold or hot.
Casinos set slot machines to payback more on the weekends.
One more rude mistake. The chances and odds are always the same. It doesn’t matter when you play.

It seems that every type of activity has its own rules of etiquette, and playing the slots is no exception. 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? If you hang a coin cup over the handle of the slot machine it will mean that this slot is in play by you. Placing the coin cup on the seat has the same meaning. In casinos that use a cashless system, a personal item such as a jacket can be placed on the seat instead. In your turn you should respect other players and never sit to a slot that is in play. If you find a card left by the previous player the second etiquette rule has to be applied. 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. 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. For jackpots that require a hand payout, the customary tip is one half of one percent of the jackpot.
