Online Slots Randomness Algorithms Revealed in Simple Words

The global online gambling market, which includes online slots, reached around $45 billion in 2023 and is projected to grow by 12% between 2024 and 2030. The number of online slots available to players in Canada is already in the thousands, providing a variety of choices from the world’s best software developers. However, there are still players who don’t realize how slots work and whether the results they show are truly random and can’t be calculated. Central to this randomness is the Random Number Generator (RNG), a key component that ensures fair play in slot games. Let’s discover more about the randomness algorithms of slot games.

Understanding RNGs in Slots

Though slots are considered simple games with clear rules and a captivating design, a complex system lies behind every game. The heart of every slot is a Random Number Generator, a computational algorithm that generates a sequence of random numbers that can’t be predicted in any way. In simple terms, the RNG produces numbers non-stop, even when the game isn’t played. When a gambler spins the reels, this RNG assigns a particular set of numbers that correspond to symbols on the reels. 

How Does a Slot Algorithm Work?

To understand how slot algorithms work, there are several important elements you should know:

• RNG: It guarantees that every spin outcome is random and independent. 
• Reel mapping: A range of symbols located on every reel is known as a reel strip, and the RNG selects symbols based on their positions on the reels.
• Paylines: Slot machines have predefined paylines, and when symbol combinations align accordingly, a player wins this round. This is the algorithm that checks symbols on the reels and defines whether they give a winning payout.
• Payout value: Every symbol has a special payout value, which the algorithm calculates based on the outcome.
• Return-to-Player (RTP): This is the percentage of wagers returned to a player over time, and the algorithm ensures that payouts are aligned with the RTP rate.
• Volatility: This index defines how frequently a payout is received, and the algorithm is adjusted to guarantee the volatility a game developer sets.
• Bonus feature: The algorithm also triggers a bonus game using RNG.

To ensure fairness, slot algorithms are regularly tested and certified by independent regulators. Additionally, game developers continuously monitor their slots, making necessary adjustments to guarantee balance and fairness in gameplay.

Slot Game Algorithm Evolution

There are two major types of RNGs: True or Hardware RNGs and Preudo or Software RNGs. The first ones are more complex and costly, so they aren’t used in slots very often. You are more likely to see software RNGs that rely on algorithms and math formulas that guarantee randomness. However, slot algorithms are evolving constantly, having transitioned from mechanical systems to digital and more sophisticated ones. Naturally, players can observe various changes in slot algorithms nowadays, so let’s take a closer look at these developments.

Shifting from Mechanical to Digital

One-armed bandits rely on physical reels and simple RNGs, so they have limited possibilities with a restricted number of paylines and symbols. Modern online slots use enhanced RNG algorithms, which make games more dynamic and feature thousands of potential combinations.

Cryptographic RNGs

Cryptographic RNGs differ from traditional ones, with more complex encryption techniques to guarantee slot randomness and security. These RNGs are tamper-proof, so they aren’t vulnerable to hack attacks and don’t allow predicting outcomes.

What to Expect from Slot Algorithms in the Future?

The development of technology shapes the future of gambling in general and slot algorithms in particular. Anticipated advancements include the integration of artificial intelligence and machine learning.  These technologies could lead to the creation of more sophisticated RNGs that can adapt to players’ behaviors. This adaptation may allow for adjustments in volatility and create a more personalized gambling experience, enhancing player engagement.

Additionally, blockchain technology is set to revolutionize the fairness of slot gambling. It allows for the development of transparent and reliable RNGs that players can verify in real time. Furthermore, the rise of virtual and augmented reality is anticipated to make the gambling experience more immersive. As these technologies become mainstream, software providers will need to consider developing more advanced RNGs that can support the complexities and dynamics of immersive gameplay.
