Slot games – also known as slot games – are one of the most popular game genres in online casinos. With simple but attractive gameplay, slots attract millions of players worldwide. However, many people still ask the question: What algorithm does slot game use? Is this game rigged? The following article by In 999 will help you clarify the operating mechanisms behind slot games, including the algorithm used, randomness, and the level of reliability when participating in online betting platforms.
1. What is the algorithm used in slot games?
1.1. RNG (Random Number Generator) algorithm
Modern slot games use the RNG algorithm – short for Random Number Generator – to create completely random spin results. This is a form of strong encryption algorithm, ensuring that:
Each spin is an independent result, not affected by the previous spin
There is no way to predict or interfere with the results
Players and the house cannot control the spin results
RNG is the heart of every online slot game today, ensuring absolute fairness without unauthorized interference.
1.2. Probabilistic and combinatorial algorithms
RNG does not work alone. It is often integrated with probability algorithms and symbol combination sequences to determine the displayed results:
The system will randomly select a combination of symbols on the reels
Each combination has a different probability of appearing depending on the game structure
High-paying symbols often have a low probability of appearing
2. RTP index and its role in slot games
2.1. What is RTP?
RTP (Return to Player) is the return rate to the player, indicating the level of profit the player can receive in the long run. For example:
A slot with an RTP of 96% means that, on average, the player will receive 96 coins back on 100 coins bet after a large number of rounds.
2.2. RTP does not affect each specific round
RTP is a long-term statistical value, not a guarantee that each spin will be reasonable according to that ratio
A player can win big or lose everything in a short time, completely randomly
However, if played long enough and enough, RTP will accurately reflect the probability of profit
3. Can slot games be cheated?
3.1. Cheating from untrustworthy developers
Some unlicensed platforms can write their own games or interfere with the source code to adjust the RNG
As a result, players will always lose, or the winning rate will be much lower than announced
This cheating is very difficult to detect if the publisher does not announce the actual RTP or does not independently verify
3.2. Fraud from non-transparent bookmakers
Although the game developer is reputable, some bookmakers may use modified versions of the game or have incorrect configurations
Bookmakers without international operating licenses often have a high risk of dishonesty
Players may have their accounts locked, their rewards denied, or their withdrawals delayed
4. How to know if a slot game is fraudulent or not?
4.1. Check the publisher and bookmaker licenses
Play games from reputable developers such as: NetEnt, Microgaming, Playtech, Pragmatic Play
Choose a bookmaker certified by: MGA (Malta Gaming Authority), Curacao, eCOGRA, iTech Labs
This license ensures that the game is not tampered with and is regularly checked
4.2. Compare published and actual RTP
Some games publish RTP but the actual results are very different
You can check RTP information from the publisher’s homepage or independent game review portals
4.3. Read reviews from the community
Visit forums like Reddit, Trustpilot, Casino.org to read real comments from players
Signs of cheating are often widely shared by the community
5. Do slot games have winning strategies?
5.1. There is no way to “hack” RNG
RNG cannot be controlled by “tricks” or external software
The cheating tools advertised online are all scams
5.2. Can optimize the playing experience
Although the outcome cannot be controlled, players can increase their chances by:
Choosing slots with high RTP and low volatility (easy to win small, frequent prizes)
Managing the budget effectively, not betting too much in a short time
Prioritizing demo games to understand the game rules before betting for real
6. Developers using reputable RNG algorithms
Here are some famous slot game developers using certified RNG algorithms:
NetEnt: famous for games like Starburst, Gonzo’s Quest
Microgaming: long-standing, has hundreds of slots with high RTP
Play’n GO: creative, transparent game design and independent certification
Pragmatic Play: famous for slots with attractive features, transparent RTP
All are certified by organizations like eCOGRA, ensuring RNG operates according to standards.
Slot games use RNG algorithms to ensure randomness and fairness, but that is only really reliable when you play at reputable, licensed casinos that cooperate with certified game developers. Although it is impossible to cheat from the player side, some less transparent casinos can still interfere with the system if not managed.
So, before investing time and money in any slot game, make sure you understand how it works and choose the right place to play. High RTP, standard RNG, clear license – these are the key factors to ensure a safe and fair slot game experience
