Slot Machine Cheating
Some of the ways slot players can get themselves into trouble may originally be unintentional. The most common violation of laws regarding slot play has already been mentioned it is informally called claiming and can occur in a variety of situations in which the players falsely claim that the slot machine has malfunctioned. The most obvious ploy is stating that they have more money coming because the machine didn't pay them at all or that it only paid part of what they should have won. In other words, the customers falsely state that they received a no pay or a short pay.
Of course it is possible for no pays and short pays to occur on any slot machine. If this should happen to you, just call a casino employee, who will get a mechanic to help you. You don't have to worry about being accused of cheating. For one thing, an inspection of the machine will usually confirm that you are correct about what happened. Secondly, even when the machine offers no evidence of not paying or of short paying, and if it is only a question of a few coins, many casinos will give you the benefit of the doubt. So don't be afraid to speak up if you have this kind of problem, it's when the same customer reports the same problem over and over again that the casino becomes suspicious.
Another kind of claiming has to do with customers who insist that a slot machine they were not playing owes them money. It works like this. These dishonest players will find a machine on which someone else previously won, took the money, and walked away without playing off the jackpot. Then pointing to the winning symbols the previous player had lined up on the payline, these customers will now claim they were playing that machine but "no money came out." Even though the machine will show that the real winner was paid, these players will insist they are the winner and thus have money coming. If you try this approach a few times, don't be surprised if big trouble and unfriendly faces show up.
Next comes the more overt and obvious attempt to play a slot machine for free by inserting foreign coins or slugs, better known as slugging. The amateur cheat's most popular practice is using foreign coins of a size similar to US coins. The serious slot cheat will use non-magnetic washers or most commonly will make or acquire lead slugs the size of dollar coins and tokens. The really hard-core "slugger" will counterfeit actual casino dollar tokens, a few of which look almost like the real thing. Any person observed and caught slugging a slot machine, even if they claim only to be seeing if it would work or just fooling around, stand a very good chance of being arrested. Anyone thinking of giving it a tray ought to think again. This is not the way to win at playing slots.
By the way, almost no one tries it these day, but stringing a slot machine is not feasible for several reasons. Stringing means taping, tying, gluing, or otherwise affixing a string or fine wire to a coin and then inserting and retracting it from the machine in order to get free plays. Cheating in this fashion has become impractical due to anti cheating devices in the machines as well as the fact that it's hard to string a machine without being seen. A person would have to be pretty stupid to give this a try.
Finally, there's silvermining, which may not be exactly a form of cheating but might qualify as the next thing to it. Silvermining is the activity of looking for stray coins in advertently left in the tray of slot machines or dropped on the floor by other customers. You're not a silverminer if you just pick up a coin or two you find on the floor or in a slot tray, but it does become a problem if you make it a near full time occupation. Being a silverminer is definitely not a good idea.
