It is undeniable that the advent of digital technologies has transformed slots from simple three-reel machines with a lever to feature-rich games filled with special symbols and bonus games. This article provides extensive information about the Random Number Generators (RNGs) all modern landbased and online slots run on.

What is RNG?

The abbreviation RNG stands for Random Number Generator, a term that sounds pretty self-explanatory. However, there is more than meets the eye when it comes to the RNG. It has been a crucial component since the advent of video slots in the 1980s. It wouldn’t be far-stretched to describe it as the heartbeat of all modern slots. Think of the RNG as the digital pulse that keeps a slot game running and ensures fairness and unpredictability of outcomes.

Key Takeaways

  • The abbreviation RNG stands for Random Number Generator, essential for the fairness and unpredictability of modern slots.
  • The transition from mechanical to digital slots was made possible by the RNG.
  • Every slot game crafted after the 1980s utilizes an RNG to produce random outcomes.
  • The RNG works continuously even when nobody plays the respective slot.

Transition from Mechanical to Digital

Remember those old-school slot machines with mechanical reels? The RNG is their digital successor.  When progress ushered in digital technologies, slot machine vendors were faced with a challenge. They had to figure out how to make the digital reels produce random outcomes like their mechanical predecessors. This is where the RNG came in. It was the game-changer that paved the way for the leap from mechanical to digital, ensuring that every spin is as random and unpredictable as flipping a coin.

Understanding RNG Slots

So, what exactly are RNG slots? In layman’s terms, any slot game post-1980s is an RNG slot. Unlike their mechanical predecessors, RNG slots don’t rely on physical reels. Instead, they use software to generate millions of random numbers, each corresponding to a specific symbol on the reels. Here’s a fun fact: even when no one’s playing, the RNG is tirelessly cycling through these combinations.

The Science Behind the Spin

Each number the RNG spits out corresponds to symbols on the reels, with some symbols represented by multiple numbers. This is known as a virtual stop. When you hit that play button, the RNG selects a combination at random, determining where the reels will stop. It’s like a digital roll of the dice, ensuring each spin is a standalone event, completely unaffected by previous or future spins.

True RNG vs Pseudo RNG

The Tale of Two RNGs

In the enchanting world of random number generation, there are two distinguished characters: True Random Number Generator (TRNG) and Pseudo Random Number Generator (PRNG). While both strive to fulfill the same destiny – generating random numbers – their paths are strikingly different.

TRNG: The Unpredictable Maestro

  • The Essence of TRNG: Think of TRNG as a maestro conducting an orchestra of randomness through physical means. It’s a hardware device that relies on environmental factors like atmospheric pressure, air temperature, or even player interactions to create unpredictability.
  • Mechanism of TRNG: This hardware device measures these environmental variables, converts them into digital values, and voila! You have a result that’s as unpredictable as the weather.

PRNG: The Algorithmic Illusionist

  • PRNG Defined: In contrast, PRNG is like a skilled magician performing a well-rehearsed trick. It’s a software algorithm that generates a sequence of numbers based on a specific starting point, known as the ‘seed’.
  • The Role of the Seed: The seed is the secret sauce of PRNG. It’s the initial input that kick-starts the algorithm, leading to a chain of numbers that appear random but are actually the result of a complex mathematical dance.

Comparing TRNG and PRNG

  • Unpredictability vs Determinism: TRNG’s randomness is pure and unadulterated, as it’s derived from physical randomness. PRNG, meanwhile, is a master of illusion, creating a semblance of randomness from a deterministic process.
  • The Predictability Factor: Theoretically, if you know the seed and the mathematical principles behind a PRNG, you could predict its outcomes. TRNG, on the other hand, remains elusive and unpredictable.

Key Takeaways

  • TRNG uses physical processes to generate pure randomness, making it unpredictable.
  • PRNG employs a deterministic algorithm, making it theoretically predictable if the seed is known.
  • Both TRNG and PRNG play crucial roles in different applications, each with its unique advantages and limitations.

So, in the realm of RNG, we have two distinct yet equally fascinating characters: the unpredictable TRNG and the algorithmic illusionist PRNG. Each has its role to play in the grand scheme of randomness, bringing a unique flavor to the world of chance and probability.

Adjusting Slot Odds

The Secret Behind Slot Machine Odds

Have you ever strolled through a casino and wondered why some slot machines seem to be the lucky ones? It’s not just luck; it’s about the ‘Return to Player’ (RTP). But how exactly do casinos adjust these odds, and what does it mean for your chances of winning?

Understanding RTP

  • What is RTP?: RTP stands for ‘Return to Player’ and represents the percentage of stakes a slot machine returns to players over time. For instance, an RTP of 94% means the machine will pay back $94 for every $100 wagered, on average.
  • Variability in RTP: Slot machines, especially in places like Las Vegas, come with varying RTPs – from as low as 88% to as high as 98%. A casino might have several identical slot machines with different RTP settings like 90%, 92%, 94%, or 96%.

Placement and Adjustment of Slot Machines

  • Strategic Placement: Ever noticed how the most enticing slot machines are often near the entrance or the buffet? Casinos strategically place machines with different RTPs, but where the high-paying ones are located remains a well-guarded secret.
  • Myth Busting: RTP Adjustment During Play: Contrary to popular belief, casinos don’t – and legally can’t – change the RTP while a game is in progress. No one’s flipping a switch behind the scenes when you start winning.

The Invisible Adjustment of Odds

  • Subtle Changes in the Game: Adjusting RTP isn’t about grand gestures; it’s often as subtle as swapping a cherry for a bell on the reel. Other adjustments might include tweaking bonus awards or their frequency.
  • Consistency in Odds: One crucial aspect to remember is that the odds of winning remain constant with each spin. Whether it’s your first or hundredth time pressing the button, your odds of hitting the jackpot are the same.

Key Takeaways

  • RTP varies across slot machines and is a critical factor in the game’s payback.
  • Casinos strategically place machines with different RTPs but cannot legally alter them during gameplay.
  • Adjustments in RTP are made subtly, often going unnoticed by players.
  • The odds of winning are consistent with each spin, maintaining the game’s fairness.

In the world of slot machines, RTP is like the invisible hand guiding your fortunes. While the casinos play their strategic game, remember, each spin is a new opportunity, with odds as constant as the spin of the reels themselves.

Other Slot Factors that Play a Role in Understanding Slot Results

Beyond RNG: Understanding Slot Mechanics

When it comes to slot machines, RNG isn’t the only player in the game. Other factors like hit frequency, slot volatility, and Return to Player (RTP) crucially shape your slot experience. But how do these elements interplay to determine your fate with each spin?

  1. Calculating Hit Frequency
    • Defining Hit Frequency: It’s a percentage indicating the likelihood of a payout on any given spin. For example, a 20% hit frequency means there’s a 20% chance of winning something on a spin.
    • Hit Frequency’s Visibility: Unlike RTP, players can often sense a game’s hit frequency. Games like Mega Vault by IGT have low hit frequency but offer massive wins, while others like Enchanted Unicorn offer more frequent, smaller wins.
  2. Hit Frequency vs Payback Percentages
    • No Direct Link: Understanding hit frequency doesn’t directly reveal a game’s payback. A game designed with high hit frequency could still have a low RTP.
    • Design Adjustments: Games with lower payouts might maintain the same hit frequency by offering more frequent small wins instead of big ones.
  3. Hit Frequency and Slot Volatility
    • Indicators of Volatility: Hit frequency can be a telltale sign of a slot’s volatility. High volatility games tend to have lower hit frequencies with bigger wins, while low volatility games offer more frequent but smaller wins.
    • Game Examples: Enchanted Unicorn represents a low-volatility game with high hit frequency, whereas Mega Vault falls into the high-volatility, low hit frequency category.
  4. Understanding Slot Volatility
    • Volatility Index (VI): This index measures how often a slot triggers wins and the typical size of those wins. High volatility slots pay big wins less frequently, while low volatility slots offer smaller wins more often.
    • Volatility Types: Slots range from low to high volatility, including medium-low, medium, and medium-high variants.
  5. Volatility vs RTP
    • Different Measures: Volatility indicates win frequency and size, whereas RTP reflects the overall payback to players. Both high and low volatility slots can have high RTPs.
  6. Finding a Slot’s Volatility
    • Casino Info and Online Research: Some casinos list volatility in their slot info. Alternatively, a Google search like “Mercy of the Gods Slot Volatility” can yield results.
    • Demo Mode Exploration: Playing a slot in demo mode offers insights into its volatility.
  7. What is RTP?
    • RTP Explained: Return to Player represents the average amount a slot pays back to players over time. For instance, a slot with 96% RTP is expected to return $96 for every $100 wagered.
    • RTP’s Long-Term Nature: Remember, RTP is calculated over millions of spins, so short-term results can vary widely.

Key Takeaways

  • Hit frequency and slot volatility are critical in understanding a slot’s behavior.
  • High hit frequency doesn’t always equate to high payback.
  • Volatility affects the size and frequency of wins.
  • RTP gives a long-term perspective on a slot’s payback potential.

Understanding these elements can significantly enhance your slot-playing strategy, providing a deeper insight into what to expect with each spin. Ready to spin with a newfound perspective?


What Is a Random Number Generator (RNG) in Slot Machines?
