Every casino game has its own rules, features and of course etiquette. Slots are not an exception here. 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. 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.

You can be sure that slot machines are designed to be honest. However, in the past certain manufacturers have been caught using computer chips that cheat the customer.
The very first slot machines worked according to the following principle: the wheels spun and then each of them stopped randomly. Modern slots are much different. Now the integral part of any slot machine is a chip, which is programmed to select numbers randomly. The numbers the computer selects correspond to the symbols that appear on the slot machine’s screen. There is a computer code. It generates the random numbers and determines whether the slot machine is loose or tight. The gaming inspector will examine the machine to make sure it will not deceive the player. The machine has to pay out either to the legal rate or better. Of course the latter happens very seldom.
Because slot machines don’t pay off with every spin, it’s difficult for customers to tell whether a slot machine’s chip has been programmed to pay off less often than is legally required. The machines have to be examined before people begin to play them. Of course it is very difficult to examine every single machine, that’s why inspectors examine only brands. In the case of the approval of the brand the manufactures can produce the slot machines, even change them if it doesn’t go out legal bounds. Using their right to produce slot machines they insert different chips, which makes the machine pay less.
For example, the Nevada Gaming Commission caught American Coin using chips that did not allow poker royal flushes. Or a chip that shows near misses of a jackpot. One the one hand the machine would never have a jackpot and the player would keep on playing. Don’t keep silent if you come across such slot machine. Inspectors will respond by pulling the slot machine’s chip and seeing if it is an approved chip. Manufacturers that cheat are fined or they can lose their license.

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.
Tommy is now 53 and he can be said to have spent all his life inventing different devices to cheat slot machines. He was caught with one, called a top-bottom joint, and sentenced to prison. 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. He fooled a manufacturer into believing he was a customer and showing him the inside of a slot machine. It was enough for Tommy. 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. He sold these wands and could earn up to ,000 a day. Now he could afford the most expensive cars and several houses.
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.
