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.

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. To do it you have to hang a coin cup over the handle of the slot machine. Placing the coin cup on the seat means the same. 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 if you see somebody’s belongings or a coin cup never sit to this slot machine. You can sit to any other slot machine. The second tip has to do with the player card that has been left behind. Sometimes you can find in the slot machine a card left by the previous player. 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. While most casinos do allow smoking, it is important for those who smoke to be courteous to others, and to position the ashtray in a manner which inconveniences other players the least. 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. In the case of a jackpot tip him with 0,5% of your jackpot.

There is a man who managed to cheat slots.
Slot machines pay on a random basis, but what if you could improve the payout a little? Would you do it? Tommy Glenn Carmichael would and did.
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.
When the slots were computerized he needed a new tool. In some way he managed to fool the manufacture who showed him the inner construction 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. 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 good thing will end one day. 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.
