You must be curious about how slot machines work or how online slot algorithms fit into the whole thing.
Whether you’re playing slots online or in a real casino, the result of each spin is determined by the slot’s algorithm. Slot machines use different types of algorithms, but the Random Number Generator (RNG) is the most common.
Most modern slot machines use an RNG algorithm to determine the outcome of the spinning reels. It is generated by a computer within the slot machine or at a central server. The algorithm generates a sequence of numbers, which corresponds to the symbols on the reels.
This is how modern slot machines and online slot games determine results, and ensure fairness, and unbiasedness in their gameplay.
When you pull the lever or press the ‘spin’ button, the RNG is triggered and begins generating a sequence of numbers at high speeds. Moreover, the RNG stays functional even when the machine is idle, ensuring maximum randomness in slot machines.
Symbol Mapping
Each number generated by the RNG corresponds to a symbol on the reel. For instance, if the slot game features 5 reels, the RNG will assign numbers 1 to 5 to each reel. When you spin the reels, the position of the reels is based on the numbers determined by the RNG.
Calculating Paylines
Slot games feature paylines where symbols must align to win. The slot algorithm(RNG) determines the reel’s results against these pay lines.
Determining Payouts:
The payouts are determined according to the position of the reels and the winning combination. Slot machine algorithms calculate the payout based on which combination has landed and the amount of the player’s bet.
Return to Player(RTP)
Every slot game features an RTP ratio which indicates the average amount returned to players over time. The slot game algorithms are used to ensure that over a large number of spins, the payouts align with the RTP percentage of the slot machine.
Volatility
The volatility determines how often a slot machine will offer payouts. Dedicated slot algorithms are used to determine whether the slot game will feature low, high, or medium volatility.
Bonus Features
Some slot games also feature bonus rewards like free spins or multipliers. The Random Number Generator(RNG) is used to determine when these bonuses will be triggered, ensuring randomness and fairness.
Fairplay
To ensure fairness and maximum efficiency, the RNG algorithms used in slot games are regularly maintained and certified. These tests verify the authenticity and ensure that the slot machine algorithm provides truly fair results.
Typically, two types of RNG are used in slot machines- true RNG and pseudo RNGs.
True RNGs
This type of RNG relies on physical components like electronic noise to generate random results. While they are quite reliable, they are rarely used in online slot games due to cost constraints.
Pseudo RNGs
This type of RNG is most commonly used in online slot games. It relies on algorithms and formulas to generate random numbers.
Besides these RNGs, there are 3 primary types of slot game algorithms that enhance the gaming experience.
Round Robin Slot Algorithm
The round-robin slot algorithm is a simple scheduling algorithm that is used to ensure that every player has equal access to bonus features like free spins. Each player is assigned a fixed time slot. When one player completes their turn, the next player in line receives their chance.
Fair Queuing Slot Algorithm
This algorithm is used to provide fair resource distribution among multiple players. It is used to manage access to features like bonus rounds, ensuring all players receive a fair chance and minimizing biasedness.
Weighted Fair Queuing
This is an advanced version of the Fair Queuing algorithm. It allows different users to have different levels of priority. For example, a high-stakes player will have quicker access to special bonuses than casual gamblers.
How do Slot Machine Algorithms Determine Outcomes?
Slot enthusiasts often wonder, Are slot machine algorithms rigged? How exactly do they determine outcomes?
A number is assigned to each symbol. The RNG algorithm runs behind the scenes calculating and generating random numbers. These numbers determine which symbols will be displayed on the reels and on which pay lines. The complete process is almost instantaneous.
The reel’s final positioning is based on the RNG algorithm itself.
Now, you must be wondering- why casino operators use slot machine algorithms like the random number generator. Here’s why-

What is RTP in Slot Games?
In the realm of slot games, Return to Player (RTP) stands as a pivotal metric that is frequently neglected by many players. Essentially, it signifies the percentage of wagered funds that a slot game is programmed to return to players over an extended period. Slot machines in the USA are required by law to display their payout percentages. While this concept may appear intricate, it is imperative to grasp its significance.
In simple terms, a slot with an RTP of 95% is designed to yield $95 for every $100 wagered. However, it is crucial to note that this outcome materializes over a substantial number of spins rather than within individual gaming sessions.
The core essence of RTP is embedded within the algorithms that govern slot machines. As previously mentioned, these algorithms leverage Random Number Generators (RNGs) to ensure that each spin is completely random and unaffected by previous spins.
By meticulously adjusting these elements, slot game developers possess the ability to finely calibrate the RTP to align with their desired outcomes.
By now, you must have understood the significance of slot machine algorithms. Given how important they are, they are subjected to rigorous testing and certification. It is the responsibility of slot game development companies to ensure that their RNGs adhere to industry standards and regulations.
