There is hardly any strategy that can be applied to slots. Never believe if somebody says that he has an incredible winning strategy. The machines have no memory, so there is no effective way of outsmarting them. But there are some tips, which you can use as a basic strategy. Try to play slot machines that have the highest payout. You want to find anything 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. If you are more likely to exceed this limit you’d better give up the game. When playing remember that you can win as well as lose. The machine will not feel bad if you spend a lot of money and don't get anything back. Give up the machine that isn’t paying out and is not going to. If the machine pays out good you’d better make higher bets. When you're slumping, bet less. Find a machine that suits your bank-roll. If you have little money you’d better paly dollar machines. Don't forget to cash out the credits you've accumulated. Sounds obvious, but a lot of people forget! Try to play the slots or games you have played before.

I tis important to now what you are playing.
Only the correct amount of money should be inserted into a machine. Always cash out your credits before leaving a machine.
Just have fun. Slots should be fun, not stressful. Use money management. Increase your bets when you are winning, and decrease your bets when you are losing.

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. The first piece of slot machine etiquette is to determine deal or not to deal with particular slot machine. It can be difficult for the solo slot player to save a machine when they go to the rest room or to get a drink, but there are signals that can be used to indicate that a 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 means the same. If you play in the casino that uses a cashless system you can just leave the jacket or one of your belongings on the seat. If you see any of these signals at a particular machine, be sure to respect the signal and move on to a free machine. The second etiquette rule concerns the card left by the previous player. 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. 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 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.

Nevada or Atlantic City have more Class III slots than any other state. They are sometimes referred to as "Vegas-style slots".

Have you ever met a man who has managed to cheat slots?
It is impossible to cheat the slot machine, but to improve the payout is possible. It was proved by a gambler whose name was Tommy Glenn Carmichael.
A 53-years Tommy all his life tried to invent some kind of devices to cheat the slot machine. His first invention worked, but not for a long period of time as he was sentenced to prison for using it. Upon his release, he continued to work on the problem and to devise a better way to cheat the new slot machines. The principle of his next invention was following: he inserted a guitar wire in the slot machine and it made the coins release from the hopper.
Later the slot machines were not any longer mechanical, they were computerized and as a result there appeared a need for a new device. Tommy found a manufacture who showed him the inside of a slot machine. From that experience, he learned what he needed to know to beat it. Carmichael invented what he called a “light wand. ” The wand, built with a camera battery and a bright miniature light, was used to shine into the slot machine and blind a sensor, causing the hopper to pay out coins. Carmichael marketed these wands to other slot cheats, making as much as ,000 a day. With all this money he bought expensive cars, houses and what not.
But as known good things can’t last forever. Tommy was caught using his invention in one of the casinos. He was fined, but soon came back to the same business. By this time, authorities had tapped his phone and recorded conversations with other cheats who used his device. Three years’ probation and expropriation was the punishment. He has been banned from entering any casino.
