Slot machine video from casino expert Steve Bourie that teaches you the insider secrets to winning at slot machines and how a slot machine really works. 2 days ago The slot games do not function in the form of a cyclical basis. It can be hence said that the slot machines are genuinely unpredictable. The functioning of the slot machines. Manage your bankroll. To built up a gaming strategy, the slot player must first of all decide on the. Slot machines are designed to be tamper proof to both the players and the casino. Cabinet & screen The cabinet and screen act as a faraday cage to disperse electricity and ground electrical signals, preventing outside electrical signals from interfering with the machine’s processes. This explanation of how slot machines work included the various player interface areas on the front of a typical slot machine. There are additional relatively minor interface areas. These areas include audio speakers, audio volume control (optional), display lights, lever arm, and a hearing aid jack to accommodate those with a hearing disability.
Slots are electro-mechanical gambling machines that use randomized numbers and produce probable results.
Payout table
The pay table shows the player what combinations pay out and how much.
Winning lines
Most machines have multiple winning lines on the reels, so options are given for how many lines the player wants to bet. Each line is equal to one bet, so on a five-cent machine, betting on five lines would equate to betting 25 cents.
Coin bin
Though many machines print redeemable tickets, machines that pay out in coins have a large bin to catch them.
Credit meter
A credit meter keeps track of how much credit the player currently has as well as winnings when the reels are spun.
Credits are often used instead of showing actual cash amounts because, to the player, losing credits may not seem as negative as losing money.
Arm or button
Once the player has selected how many lines they want to bet, pulling the arm or pressing the bet button locks the settings, selects a random number, and spins the reels.
RNG
The RNG continuously generates thousands of numbers per second while the machine is on.
Some RNGs may use a device that collects thermal noise and converts it into electrical signals to help generate the numbers, as computers alone are only able to generate pseudo-random numbers.
EPROM
The EPROM (Erasable Programmable Read-only Memory) controls the weighting of the machine to make sure the desired payout percentage is reached.
(See “Odds & Weighting' section below).
Bet button
When the bet button is pressed, the number generated by the RNG at that exact moment is selected and used.
Reels
Reels are for show, and by the time they’re spinning the machine already knows what the outcome will be. Spinning and stopping reels in sequence helps build suspense and excitement for the player, keeping them more interested.
Stops
Each reel usually includes 20 to 30 stops, which are the symbols and blank spaces on the reel.
Odds & Weighting
Over many random play sessions, odds are predictable. By adjusting payouts for winning spins, casinos observe legal requirements while delivering an entertaining experience.
Payouts
Odds are predictable over time,
so adjusting payouts per possible winning spins
yields predictable results over many random play sessions
How Does A Slot Machine Work
Required legal payout percentage
Many states have laws that require certain payout percentages. For example, a machine that returns 85 or 90% of the cash it receives over time would still give the casino a 10% - 15% cut.
Weighting
The programmable EPROM allows weighting to fine-tune the play experience.
For example, if a reel has 10 blank spots, as long as that quota is met, it doesn't matter which blank spots are used. The machine could be programmed to land on blank spots around jackpots to give the player the impression of a 'near win.'
Stacking the odds:
multi-reel machines
On a multi-reel machine, the odds of winning decrease exponentially. For example, taking the single reel example from above and multiplying it to 3 reels (all with identical symbols as the first), the chances of a winning combination (3 of the jackpot symbol instead of 1) drop from 1/20 chance to 1/8000 chance.
Anti-tamper
Slot machines are designed to be tamper proof to both the players and the casino.
Cabinet & screen
The cabinet and screen act as a faraday cage to disperse electricity and ground electrical signals, preventing outside electrical signals from interfering with the machine’s processes. The screen is coated in a clear, electrically conductive chemical, and connects to the metal cabinet to allow conductivity between the two.
Coin comparator
The coin comparator accepts or rejects coins that are put into the machine. It compares incoming coins against a coin previously placed in the comparator (e.g. if a nickel is in the comparator, then the machine would only accept nickels).
EPROM
The EPROM is programmed and tested in factory, then placed in the machine with a tamper evident sticker over it. This style of chip is reprogrammable using ultraviolet light and must be removed from the machine to do so, which is allowed only when a gaming authority is present.

Coin dispenser
Coin dispensers use a light sensor to count the number of coins dispensed.
Reels
Reels have sensors that detect extra movement, so trying to move reels manually causes an error to display on the LCD screen and any winnings are negated.

Research & design by Animagraffs. Slot machines are an extremely popular form of gambling. The premise is simple: you insert a coin, pull a lever, and reap in cash rewards if the symbols on the reels align in a certain way. Slot machines test your luck and intuition, and, despite the simple rules, they are not boring in the slightest.
Slot machines use catchy music, fun graphics, and interesting symbols to hold the player’s attention. But how slot machines work? What are they made of and how do they determine when to pay out and when to disappoint the not-so-lucky players?
This article uses advanced terminology. If you are new to slots, you may want to check out our complete glossary of slot game features.
The Anatomy of a Slot Machine
So how do slots work? In order to find that out, you’ll need to go through video slot parts. When playing a land-based slot machine, you will see the following components:
Coin Slot/Bill Slot
This is where you put your money into the machine. You can also insert a cashed-out ticket into a slot machine and spend your winnings on additional spins.
Reels
Slot machines usually feature three or five reels, but you can occasionally come across machines with as many as ten reels! Reels are the spinning mechanisms that make the vertical positions on a slot grid rotate. Each reel has a certain number of “steps” where it could stop, and each step either contains a symbol or is blank. A typical slot machine contains about 20 stops on each reel, but this can vary.
Lever
In older slot machines, the lever would actually set the reels in motion. In modern slot machines, however, the lever just triggers the casino game’s software, which, in turn, makes the reels spin.
Play buttons
Slot machines may feature several different buttons. The most common include “Spin Reels”, “Play One Credit”, “Play Two Credits”, “Bet Max Credits”, “Cash Out”, and “Request Change.”
Coin Tray
In the past, once you would hit the “Cash Out” button, your coins would cascade out of the machine and pool in the coin tray. Now, however, it is now more common for the machine to print you a cashout voucher. These are redeemable at a redemption machine or at the cashier’s cage. Alternatively, you can insert it into another slot machine (usually through the bill slot) and go for some more spins.
Payline
The payline is the horizontal line that you can see in the center of a slot machine’s screen. In order to land a winning combination, the symbols must align on an active payline. The number of paylines available can vary from game to game, but you can only win payouts on the paylines that you place a bet on.
If there are ten paylines available, and you only bet on two of them, you can only reap those two payline’s rewards. Some machines require users to pay one credit for each payline that they would like to activate. Other machines may require multiple coins to activate a single payline.
Some slot games allow players to adjust the payline’s direction, while others are fixed. Paylines can run left-to-right or take on a zig-zag shape.
If you’re also interested in how all of these parts come together, make sure to watch this How It’s Made feature on casino slot machines:
Pay Table
A slot machine’s pay table will display all of the game’s winning combos and corresponding payouts. It will also display any special bonus, wild, or scatter symbols. Furthermore, the pay table will show the game’s current jackpot and indicate whether or not the machine is progressive. You should always check out a slot game’s pay table to educate yourself on all possible wins, payline configurations, payout odds, and information for bonus events.
Displays
Every slot machine will clearly display the basic information relevant to its users. Some common displays include:
How Slot Machines Work Inside
- Credits played. This display shows the exact number of credits that the player is betting on each spin.
- Credits. This will show the player how many remaining credits they have. When the display reaches 0, the player must deposit additional coins through the coin slot in order to keep playing. Keep in mind. each credit will align with the denomination the game requires. If a player is using a 25-cent machine and inserts a $10 bill, the display will show that the player has 40 credits available.
- Insert Coin. This display shows that the slot machine is not currently activated. Anybody simply has to insert bills or coins into the machine to begin playing.
- Winner Paid. This will show how many credits were won on the previous spin, which would be added to the player’s total on the Credits display.
- Error Code. This display will only activate if a slot machine is malfunctioning. It will show a code that assists a staff member in identifying the problem.

Types of Slot Machines
There are many different kinds of slot machines, some of which can be difficult to find. Here are some types of slots that you might come across and a short guide on how they operate.
Single-Coin Machines
These used to be very popular but are now much harder to find since most slots now accept dollar bills or require multiple coins per spin. Because these machines only accept one coin per spin, the house does not rake in as much revenue during a period of time as it would when using a multi-coin machine.
However, some old-fashioned casinos still use these types of machines. If you want a more classic gaming experience, and you want your credits to last for more spins, try out a single-coin machine.
Multipliers
Not to be confused with Multiplier symbols, a multiplier machine takes multiple coins and has a payout ratio that corresponds with the number of coins that a player uses on a spin. This type of machine was introduced in 1987 and is now the most popular type of slot machine found in modern casinos.
Multiplier machines still allow players to partake in single-coin play, but often players will choose to make the maximum bet.
Buy-Your-Pay Machines
Buy-Your-Pay machines allow players to bet between 1-5 coins on each spin. The number of coins inserted is what determines the game’s number of activated winning combos. For instance, if a player inserts only one coin, 3 “bars” would be a winning combo, but not 3 cherries. On the other hand, if they insert more coins, then both combos would be considered winning ones.
You can identify this type of machine by taking a look at the pay table. If it shows that more coins unlock extra winning combos, then you know it is a Buy-Your-Pay machine.
This kind of machine is not as common as multiplier machines. Many players avoid using them because it can be frustrating when they are just one coin shy of cashing out a great combo.
Multiple Payline Machines
How Does A Random Generator On A Slot Machine Work
Most slot machines only have one payline, which is in the middle of the game’s screen. On the other hand, a multiple payline machine has more than one active payline, as its name implies. This gives players a more exciting experience and offers more win potential.
However, players will typically need to pay an additional credit to activate each payline. When a payline is activated, it will light up.
Land-based casinos’ multiple payline machines typically offer 2-5 paylines, but sometimes more. On the other hand, online machines could have 50+ paylines!
Progressive Machines
Progressive machines are linked together by one jackpot, which can grow to gigantic proportions since it grows anytime a player inserts a coin into one of the network’s machines. When a player finally hits the jackpot symbol combination, the pool will reset. Some US gambling venues have linked together slot machines across entire states! Over the years, this type of slot machine has become very popular, since everybody wants to try their hand at winning a jackpot that would make them a millionaire.
Progressive jackpot slots have become especially popular in online casinos, and slots across various websites can be linked, as long as they use the same software platform.
Big Berthas
A Big Bertha slot machine simply refers to a machine that is gigantic and features 3+ reels. Some even feature as many as 8 reels, and each reel has 20 symbols! These machines are typically located near the entrance of a casino, to draw in attention. However, they don’t offer a great payout percentage.
Multi-Game Machines
A multi-game slot machine allows the player to switch between various games without having to sit at a different machine. For example, one multi-game machine might offer slots, blackjack, and video poker. In addition to this, multi-game machines will usually support many different currency denominations.
Other Useful Terms to Know
Hit Frequency
Hit frequency refers to how often a winning combination will land on the reels. If a machine has a high hit frequency, this means that winning combos will land more often. Machines that hit often don’t have a great payback percentage. Conversely, slot machines that have a low hit frequency will usually have a pretty significant payout rate.
Payback Rate
The payback rate, also known as payback percentage, refers to the amount of money that gamblers win, compared to how much they wager. Slot machines’ payback rates typically fall between 82% to 98%.
RNG
Each slot machine has a built-in Random Number Generator (RNG), which is an algorithm that ensures that each landing symbol is totally random and is not dependent on a player’s previous spin.
