Of course gambling is not a good habbit but cheating is the worst! But in history, many people have figured out a good couple of ways how to cheat slots. Below you will find 10 of them. Be aware, none of these methods will work online gaming sites like Slots Heaven!
10 – Cheat Code
Ronald Dale Harris was a talented software engineer who was working for the Nevada Gaming Commission. His job was to programming computer chips for slot machines. Since he was the programmer, he did left a cheat code like a signature of him. The code was activated by a specific combination of coins something like ‘’5 coins, wait, 2 coin, wait, 6 coins, etc.’’ and the machine would automatically pay out. Brilliant!
09 – Light Wand
Golden Nugget
Back in the day, when slot machines started using the optical sensor technology, Tommy Glenn Carmichael invented a light wand that could blind these small, magical sensors. It was something like battery-powered mini light attached to a wire.
08 – Fake Coins
As simple as counterfeiting. Using advanced machinery, cheaters pressed counterfeit slot machine coins out of hardened metal dies.
07 – Software Glitch
Las Vegas
Sometimes the cheat comes with the slot machine built in. The most known slot machine with its glitch was ‘’The Game King’’. To exploit the glitch, the gambler would put more money into the machine after the “double up” prompt and then switch back to the original game they were playing for $1.00. Then player would then up their stakes to the highest allotted amount and cash out.
06 –Top-bottom Joint
The top-bottom joint was a trick created by Tommy Carmichael and Ray Ming. The duo created a slider, which was made of a guitar wire and a piece of spring steel. They would snake the payout chute using the top-bottom joint until tripping the switch. Once the switch was tripped, the slot machine would empty out its payload.
05 – Computer Chip Replacement
Computer Chips
Dennis Nikrasch bought a computerized slot machine and played with it in his garage till he found a method to manipulate the computer chip inside to give him a jackpot whenever he wanted. For this purpose, he ordered the standard chips from a real manufacturer. Then he team up to obtain keys on the black market that opened slot machines. After that he would be able to open the machine to replace the chip under three minutes!
04 – Shaved Coins
As slot machine technology advanced, machine manufacturers changed optic verification sensors to prevent scams. Improved mechanisms use a beam of light to register payment as the coin dropped in. Ironically, this innovation was used against itself to perform a cheat. Shaved coins are registered by the machine but once it gets to its comparitor new mechanism which is the piece of equipment that measures the size and weight of the coin, it will be immediately kicked out because of the coins minute size discrepancy. Of course then you can use it again…
03 – Piano Wire
Piano wires
This method dates back to 1982. At the Caesars Boardwalk Regency in Atlantic City, a group of cheaters surrounded a slot machine. Each of them had a job. One of the cheaters dubbed the mechanic, pried open the front and inserted 20-inch piano wires into the slot machine’s whirring guts. The group used the piano wires to jam the clock that timed each wheel’s rotation. With the help of this method, he was able to manipulate and spin the wheels till he wins.
02 – Monkey Paw
The monkey’s paw was one of the early devices used by slot cheats. The mechanism was essentially a guitar or piano string attached to a bent metal rod. Cheater would jam it into the machine through an air vent and fish around for the switch that released the coin hopper.
01 – YO-YO
Chips
The cheater ties a thin cord around a coin and then places it in the slot until it registers a payment. Then yank out the coin and do the whole process over and over again. That simple!
I was bored and that can be a dangerous thing. Like doodling on the phone book while you are talking on the phone, I doodle code while answering questions on DIC. Yeah, it means I have no life and yes it means I was born a coder. During this little doodle I decided to make a slot machine. But not your standard slot machine per say, but one designed a little bit more like the real thing. Sure it could have been done a little more simpler and not even using a Wheel class at all, but what fun is that? In this entry I show the creation of a slot machine from a bit more of a mechanical aspect than a purely computerized one. It should provide a small sampling of classes and how they can represent real life machines. We cover it all right here on the Programming Underground!
So as I have already said, this little project was just something to play around with. It turned out kinda nice, so I thought I would share it. But what did I mean about it being mechanical in nature? Well, if you have ever played a real slot machine, not the digital ones they have in casinos now, you would see a metal case with a series of wheels. Typically it would be three wheels with pictures on them. When you put your money in and pull the handle the wheels would be set into motion. They would spin and then the first wheel would stop, followed by the second and then the third. After they have all stopped, the winnings are determined and you are paid out in coinage or credits.
I thought, why not be a bit mechanical in this slot machine design and create the wheels as a class called “Wheel” and give it the ability to spin independently of the other wheels? Have the wheel keep track of which picture (or in our case number) is flying by and report the results to the actual slot machine class. I could have done this mechanism without the need of a wheel at all and instead load up an array and have it randomly pick a number from the wheel. Little slimmer, little more efficient but wouldn’t show much programming theory.
What do we gain by recreating these Wheel classes and spinning them independently? Well, you gain a slight bit of flexibility. Independently we are able to control the speed of the spinning if we wanted to, we are able to grasp the idea of the wheel as a concept in our mind and manipulate it. We could easily built in features like if the wheel lands on a certain number it will adjust itself. Like some slots in Vegas, if you land on lets say a rocket in the center line, the machine would see the rocket and correct the wheel to spin backwards 1 spot (in the direction of the rocket as if the rocket was controlling the wheel). We could spin one wheel one way and another wheel another. We could inherit from that wheel and create a specialized wheel that does a slew of new different behaviors. All encapsulated into one solid object making the actual Machine class oblivious to the trickery of the wheel itself… encapsulation at its finest!
The machine class we create will contain 3 pointers. Each to one of the wheels. The machine itself will be in charge of a few different tasks. Taking money, issuing and removing credits, determining when to spin, telling each of the wheels to spin and checking our winnings based on some chart we create. It has enough on its plate than worrying about the wheels and reading their values.
Slot Machine Programming Code
So lets start with our Wheel class and its declaration/implementation…
wheel.h
As you can see the wheel itself is not a difficult concept to envision. The bulk of the work is in the read() method. Here we simply read the values from our internal array of integers (the values on the wheel) and return those values as an array of the three integers… representing the visible column. This column will then be loaded into our 2-Dimensional Array back in the Machine class. The 2D array represents the view or screen by which the user sees the results. Remember that the user never gets to see the entire wheel. Only the 3 consecutive values on the face of the wheel.
Here is how it may look in the real world. We have our machine with the three wheels and our 2D array called “Screen” which acts as our viewing window. Each wheel will report its values and those values will be put into the screen…
Below is our machine class…
machine.h
C# Slot Machine
This looks like a lot of code but really it is not if you look at each function. Most of them are very very simple to understand. We have a spin method which essentially spins each of the wheels, reads their values back from the Wheel class into a pointer (representing each column), then they are loaded into the 2D array one column at a time (our view screen), printed for the user to see the results and lastly the winnings are checked. The checkwinnings() method determines which rows to check based on the amount of the bet. If they chose 1 line, it checks for winning combinations on the middle row only. If they choose 2 lines, it checks the middle and top lines, 3 line bet checks all three horizontal rows, 4 line bet checks the first diagonal as well and 5 line bet checks both diagonals in addition to the lines.
How does it check the lines? Well each line is given to the checkline() helper function which compares the 3 values of the line against an enumerated type of various symbols. Here we are just assigning a symbol against each numbered value to help the programmer determine which numbers correspond to which winning combos. For instance, luckyseven represents the number 3 in the enumeration. So if it runs across a line with 3 number 3s, then it knows it hit the grand jackpot and credits the player 1000. This method makes things easy because if we ever wanted to change the win patterns later, we could change the enum and checkline method to do so. We could also build in multiple types of symbols and even let the user choose what slot machine game they want to go by. It becomes very flexible and is a testament to great design!

Lastly we can put some tests together just to show some the various aspects of how this thing works and how the programmer can use the classes…

This simply inserts a 5 dollar bill and a coin for good luck. Then bets 5 lines and spins. Despite the outcome we go and bet five lines again and spin once more. Hopefully we win something this time around! But either way, those are the classes for you and I hope you like them. As always, all code here on the Programming Underground is in the public domain and free for the taking (just don’t cause a mess in isle 3, I am tired of running out there for cleanup). Thanks for stopping by and reading my blog. 🙂
