A Random Number Generator is a microchip that constantly generates numbers at a rate of several billion per second. In slots, the RNG is everything, in the early days of slot machines a mechanical concept was used for randomization but over the past decades, the RNG process has been digitalised and therefore the RNG computer chip is not only used in slots but also in video poker and other.
Slot machines are one of the most popular parts of a casino. Whether you’re a professional or a gambling newbie, slots are the perfect opportunity to try your luck, promising fast-paced thrills with no skill involved. But have you ever wondered how these well-loved machines work?
The roaring success of online slots is a testament to how much we enjoy the slot machines in our bars and casinos. The technology may have finally made the shift into the digital world, however, this is simply the latest development in the long history of slot machines.
If you want to find out more, read on. In this article, we’ll be explaining how slot machines actually work – and why these games of chance are even harder than you thought!
How many parts does a slot machine have?
In general, traditional slot machines are made up of six parts. When you insert your money, these parts work together to activate the mechanism:
- The coin slot. Modern slot machines also usually have an in-built card machine.
- The lever. On early machines, pulling the lever would physically trigger the reels to spin, but this is now motorized.
- The reels. Slot machines contain three reels, each one notched so that it can spin around a metal shaft (and eventually stop at the desired position).
- The brakes. The braking mechanism causes the reels to stop one at a time.
- Payout trigger. These are a series of metal pins that can ‘read’ the depth of the notches on the reels in order to work out the required payout amount.
- Winning line. This is the combination of symbols that you’ll need to get to win the jackpot.
What happens when you pull the lever?
When you insert your money, the lever is unlocked so you can start to play. Once you pull the lever, a motor automatically causes the reels to spin (on some old-fashioned machines, the lever itself spins the reels).
A braking system brings each reel to a stop, one at a time. At this point, the metal payout trigger pins are used to detect the depth of the notches on each reel. This means the machine is able to identify the reels which the player has spun, triggering the correct payout. (The notch that signifies the jackpot is often a lot deeper than the other notches).
What are computerized slot machines?
Today, most new slot machines use a computerized system, rather than the motorized mechanism which drove more traditional machines.
These computerized slots rely on a random number generator, which means that each spin has a truly equal chance of hitting the jackpot. As soon as the machine is switched on, this generator is constantly cycling through a wide range of numbers. When you pull the lever, it stops suddenly and ‘remembers’ the last three numbers it cycled through.
These numbers will determine the position of the reels, with each number divided by a set amount in order to reach a value which corresponds to one of the notches on the reel.
This technology means your chance of hitting the jackpot is staggeringly small – but if games of chance are how you get your thrills, this should only add to the fun!

Editors’ Recommendations:
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?

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
Do Slot Machines Have A Random Generated Multiplier Variable
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.

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:
- 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
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.
