What Does “RNG” Mean in Gaming?


In gaming, RNG stands for “Random Number Generator,” a system that generates random outcomes in game mechanics. It can refer to unpredictable elements like loot drops, enemy spawns, damage dealt, or any other aspect of a game where chance plays a significant role.

In the world of digital gaming, the term RNG has become a ubiquitous term. But, what does it really signify? In essence, RNG, or Random Number Generator, is a mechanism that injects a hint of capriciousness into a game, making each playthrough a unique experience.

The Definition of RNG in Gaming

RNG (Random Number Generator) refers to an algorithm or a device that produces a series of numbers devoid of any discernable pattern, thus qualifying as random. When applied to video games, RNG influences various in-game events, making them different each time you play. This could entail anything from the probability of a critical hit to the rarity of an item you might stumble upon during your virtual journey.

RNG – The Game Changer

RNG could be the deciding factor in many contemporary games. It is the secret behind the uniqueness of the Pokémon you encounter, the unpredictability of the items you discover in Mario Kart, and the randomness of the treasures you uncover in Diablo.

Games that are procedurally generated, such as Minecraft and The Binding of Issac, are heavily reliant on RNG. On the other hand, rhythm games like Dance Dance Revolution or Guitar Hero, and competitive multiplayer games like Rocket League and Mortal Kombat, have a negligible dependency on RNG.

However, it’s crucial to note that not all competitive games steer clear of RNG. For instance, Counter-Strike: Global Offensive employs RNG to determine bullet impacts, while DOTA 2 uses RNG to ascertain the frequency of ability effects on opponents.

RNG – The Spice of Gaming Life

RNG is the secret ingredient that saves games from becoming monotonous. It is the catalyst of curiosity and the harbinger of risk, making it an invaluable tool for keeping a game fresh and exciting.

Take Tetris, for instance. The blocks in this game are chosen randomly. If this randomness were taken out of the equation, the game would lose its fun, stress, and unpredictability. It would boil down to a mere memorization game, devoid of any risky or clever moves.

However, in RNG-heavy games like Hearthstone, skill can often be overshadowed by luck. This has often led to a debate among gamers, especially those engaged in competitive gaming, where they feel that RNG undermines their skills.

The Art of RNG Manipulation

Despite its inherent randomness, RNG can be manipulated in certain cases. As RNG algorithms are math-based, they require variables to produce random values. These variables could be anything from the console’s internal clock to the number of objects on screen or even the sequence of buttons you’ve pressed since starting the game.

In some games, these numbers are predictable enough to be manipulated. This is somewhat akin to card counting, albeit a bit more complicated. While RNG manipulation isn’t a part of competitive gaming, it plays a crucial role in classic RPGs and retro video games, where RNG algorithms were relatively simple. By counting and pressing seemingly random buttons, gamers can secure rare items or perfect Pokémon.

The Two Faces of RNG – True and Pseudo

RNG is broadly classified into two categories – True RNG and Pseudo-RNG. True RNG involves using a physical device known as a hardware random number generator that leverages minute physical processes, such as electronic noise, to generate random numbers.

On the other hand, Pseudo-RNG uses an algorithm that performs mathematical operations on a seed value to generate a random number. A seed that’s as random as possible is used to ensure different outputs each time. While Pseudo-RNG isn’t truly random, it’s convenient, fast, and good enough for video games.

Diving into the Practical Applications of RNG in Gaming

Let’s delve into some practical applications of RNG in games to better understand its impact.

Loot RNG

RNG plays a pivotal role in loot-based games like Destiny, Borderlands, and Diablo. The reward that drops when you defeat an enemy or open a treasure chest is determined randomly each time, thereby adding a thrilling unpredictability to the game.

RNG in Determining Chance Percentages

RNG is often used to calculate the probability of specific events. For example, in RPGs, RNG determines the frequency of battles with wild Pokémon and the creatures you encounter.

Procedural Generation Through RNG

RNG forms the backbone of procedurally generated games, where game content is created through an algorithm instead of manually. Minecraft and Spelunky are popular examples of such games.

RNG and Speedrunning

RNG adds an element of unpredictability to speedrunning, where gamers aim to complete a game as fast as possible. While it often poses challenges, RNG isn’t always detrimental to speedruns. Having some variance between runs can make the game more appealing as it’s easier to improve your time with a bit of good luck.

The Good, The Bad, and The RNG

RNG is the lifeblood of many games, pumping in unpredictability and freshness. It offers variety, keeps things fresh, and adds a dash of excitement to the gaming experience. However, many competitive gamers feel that RNG undermines skill, leading to debates within the gaming community.

Wrapping Up

RNG, or Random Number Generator, is a critical component in many games, lending an element of unpredictability and freshness to each playthrough. Next time you’re engrossed in a video game, appreciate the subtle nuances brought in by RNG. And remember, whether you hit a jackpot with a rare item or land a critical hit on your opponent, RNG is at play.
