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 machine don’t remember wins or loses, they have no memory, so don’t try to overreach them. The strategy can be represented only by a number of tips. You should always be looking for the machines that have the highest payout. You want to find anything above 95%. Similar to other casino games, it is crucial to know the odds and probabilities of the machine you're 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. 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. Don’t be afraid of making higher bets if you are on a lucky streak with this very machine. When you're slumping, bet less. Play the slot machines that your bankroll can afford. Look for a dollar machine, and have some fun. Cash out the credits you’ve won before leaving the slot machine you’ve been playing. It may seem strange but some gamblers forget to do it. Always play what you know.

There exist at least two types of slot players.
The first type is a persistent player.
These players are sure that the machine is already ready to pay out, they just have to wait for a little. Any second now the slot machine will roll over and all the coins will be flying out and you will be rich.
The player has either seen a person playing a slots game for a while with no payouts or alternatively they have been depositing funds into a slots game and haven’t yet seen any payouts. They know the next big win, or any win is due to pay out. They can’t leave the machine because as soon as they do it will burst forth and pay out large sums. Maybe it can really work if you have already spent thousands of dollars and have got nothing back. The machine can’t but paying.
In the old days when a payout occurred players would feel the coins to see if they were hot or cold. If the coins were hot they believed that the machine had not paid for a long period of time. But in reality any machine has numerous lights which heat the coins.
Chaser is the next type of slot players.
The player believes the slot machine is not one of those machines that never pay. There is some kind of comfort and trust between the slot machine and the player.

Like any casino game slots have their own rules of etiquette. 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? 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. 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. The last etiquette rule is tipping a person, who brings you the winning. In the case of a jackpot tip him with 0,5% of your jackpot.

There is a man who 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. Then he was released, but continued to work at inventing devices for cheating a slot. 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.
When the slots were computerized he needed a new tool. He fooled a manufacturer into believing he was a customer and showing 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. Now he could afford the most expensive cars and several houses.
But as known good things can’t last forever. For Carmichael, they ended in front of a slot machine at Circus, where he was caught with the light wand when he tried to run from security. While charges from that incident were later dropped, he was caught under similar circumstances in Laughlin and later Atlantic City. By this time, authorities had tapped his phone and recorded conversations with other cheats who used his device. He served three years’ probation and lost both homes. He has been banned from entering any casino.
