How to Cheat Slot Machines in Casinos

Whether you’re a new or experienced slot machine player, there are certain tricks you can use to beat the house and make money on your favorite games. These tips will help you get the most from your slots, and you’ll even learn how to avoid common mistakes that could make your winnings go down in flames.

Light wand

Invented in the late 1970’s by casino cheater Tommy Glenn Carmichael, the light wand was a cleverly disguised mini light bulb that could fool the optical sensor of a slot machine into thinking it had a coin in the slot. Carmichael sold these gizmos for $1,500 each. He also created a “Monkey Paw” device that was a little more complicated.

While the light wand did the trick, the real trick was getting the device to work. After a few failed attempts, Carmichael was forced to call in the services of a security firm. The security firm had access to a slot machine and was able to install a circuit board in the machine that made the light wand work.

The real key to success was putting the light wand in the right position. It took a little skill and knowledge to get the right combination of angle and polarization, but the results were impressive. When the machine was running, the light would be able to fool the optical sensor and the jackpot prize fund would be triggered.

While the light wand is still the best way to cheat a slot machine, it is by no means the only method for winning at the game. Using the right techniques, you can rig a slot machine from the inside out. A small win could be converted to a big win and you could leave the casino a rich man.

The light wand has been surpassed by the light bulb as the best way to cheat a slot machine, but it does have its charms. While not available to the average consumer, the tidbits it can provide will certainly put you on the winning side of the coin.


Those who want to know how to cheat slot machines in casinos need to know a few things. They need to know that there are ways to cheat and the most effective ones are legal. They need to also know that these cheating techniques can backfire and get you in trouble.

One of the most popular cheating techniques is the shaved coin slot hack. This technique is still used by professional gamblers today. This trick requires the player to insert a coin into the slot machine that is just a little bit smaller than a gambling coin.

Another method that is used by slot cheaters involves the use of magnets. These magnets have the ability to stop the spinning disks in the slot machine, which can increase the number of coins that the machine will pay out.

Another popular slot cheating technique is the use of a light wand. This method is different than the physical comparator because it hacks the optical sensor. It also allows the cheater to play with a coin on a string, which is called a yo-yo.

In the 1970s, one of the most effective ways to cheat slot machines was using a magnet. Magnets were strong and were made in Russia. They would be detected easily. They were also not useful for professional cheaters.

Another method of cheating slot machines involves reprogramming the slot machine. This method is a little more complicated. It involves knowing the source codes of the slot machine and using them to your advantage.

If you are caught cheating slot machines, you may be sent to prison. You may also be fined. If you are caught, you should give up your attempt to cheat the slots.

Top-bottom joint tool

During the 1970s, the top-bottom joint was a common casino cheat. It was a long wire that was put in the coin chute to jam the slot machine’s wheel. This caused the machine to release the coins stored inside. The tiniest detail is that it was actually made of a metal rod bent into a letter “Q” shape. The device had two uses: to jam the wheel and to activate the money dispenser.

The Top-Bottom Joint was one of the earliest of its kind. It was a simple metal rod with a long wire at the bottom that was bent into the appropriate shape. The top-bottom joint lasted for more than a decade. Casinos have taken measures to thwart this nefarious invention.

The top-bottom joint has been replaced by other more sophisticated methods of cheating. Other methods include the use of a bill wrapper to fool the slot machine into thinking a real, crisp $100 bill is inserted into the machine. This will result in an inflated jackpot but will not win you the coveted slot jackpot.

The top-bottom joint was a clunky affair compared to the many other casino cheats available in the late 1960s. In addition to being a nuisance, the top-bottom joint also involved a lot of swearing. And while it may be technically possible, most casino security staff are on the lookout for such tricks. For a casino-going public, the top-bottom joint is best left to the professional. If you are considering this type of trick, be aware that the chances of winning are slim to none.

The top-bottom joint has been superseded by modern slot machine technology. A better method of cheating a slot machine will include using a special device to activate the money dispenser.

Shaved and stringed coin trick

Using the shaved and stringed coin trick to cheat slot machines in casinos is not as effective as it used to be. Modern technology has made the cheating process very difficult. Modern slot machines use a random number generator (RNG) to determine the results of the spins. This makes it impossible for a programmer to predict the results.

Before the invention of the light sensor, slot machines used a physical comparator to determine if a coin was inserted. However, the light sensor worked independently from the physical comparator. In fact, the light sensor used to register the insertion of a coin was invented by Tommy Glenn Carmichael.

This type of scam was popular in the 1980s and 1990s. The gang of scammers would attach wires to the whirring guts of the machine. These wires would jam the wheel rotations and the mechanical clock. This would enable the group to manipulate spins, and the winning combination would trigger a cash out.

In the 1970s, casino scammers used a top-bottom joint tool, which was a metal rod bent into a letter “Q” shape. The bottom of the joint tool was connected to a long copper wire. These wires would be inserted into the coin chute.

Another popular cheating technique was using a monkey paw tool, which was a bent metal rod attached to a guitar string. The monkey paw tool was then placed into the coin slot. The user then twisted the rod until a trigger switch was hit. The result was that the stored coins would be revealed.

Another method was to use a bill wrapper. This device would fool the slot machine into thinking the bill was a hundred dollar bill.

Abusing the return to player percentage

Whether you are playing in a brick and mortar casino or online, the return to player is a concept that should be considered when it comes to gambling. This isn’t to say that you can’t get a better return playing online or on the go, but you’re going to have to put up with a lower than expected return if you want to make money playing slots.

The return to player is a simple concept. You can expect to get back a few dollars for each dollar you bet, but not much. Unless you’re playing on a slot machine with a ninety percent payback, you’re not going to get back as much as you’d expect.

The return to player is not the only way to calculate the cost-of-play. A provider can set up a relationship with you so that you know the best payback percentage for your machine. Some providers allow you to adjust the RTP on your own. This is a good idea if you’re looking to increase your chances of winning, but it can be quite time consuming.

A few years ago, the gaming control board in the UK published the return to player for electronic gambling machines. Apparently, the RTP is a good indicator of the performance of the machine in question. The return to player for slots is usually about 75%, but can vary dramatically from one jurisdiction to the next.

A 93 percent payback machine is designed to give you back 93 percent of your wager. However, the actual return might be lower than this. In fact, a recent study by the University of Waterloo suggests that casinos lose money on their slot machines.
