Why Games Cheat Their Own RNG (And Why You Like It)

Many players swear that video game randomness is rigged. You miss three 90% shots in a row, enemies land impossible hits, or a crucial coin flip goes the wrong way and you rage-quit to social media. But in a lot of modern games, your hunch that the numbers are being massaged is absolutely correct — the game is cheating. What’s surprising is that, more often than not, it’s cheating in your favor.

Strategy series like XCOM popularized this idea with systems that secretly adjust hit chances behind the scenes. Newer narrative and indie games, including titles like Dispatch, have started borrowing similar tricks. Rather than using pure, unforgiving randomness, they use a curated version of RNG (random number generation) tuned to feel less cruel and more dramatic.

Understanding RNG: More Than Just Dice Rolls

At its core, RNG is exactly what it sounds like: a way for computers to generate unpredictable outcomes. Technically these are pseudorandom numbers, but for gameplay purposes they’re close enough to random that players can’t predict the next result.

Developers use RNG in a wide range of systems:

• Combat resolution (chance to hit, critical strikes, dodges)
• Loot tables (what drops from enemies or chests)
• Procedural generation (level layouts, enemy spawns, events)
• Branching narratives (random outcomes or events between key story beats)

In theory, a truly random system is simple: you give it a probability and it produces outcomes that, over a large number of trials, match that probability. The trouble is that players rarely experience “large numbers of trials” in a single session. They live inside the short runs where streaks and bad luck feel deeply unfair.

Why Perception Matters More Than Pure Math

From a statistical perspective, hitting or missing a 90% shot three times in a row is unlikely but perfectly possible. From a human perspective, it feels like being personally targeted by the game. Psychologists have long documented how people misjudge probabilities and randomness:

• Gambler’s fallacy: expecting a heads result after a streak of tails, even though the next coin flip is still 50/50.
• Clustering illusion: perceiving patterns in random data (like seeing meaningful streaks that are just noise).
• Negativity bias: remembering painful experiences — like a missed 95% shot — more vividly than normal successes.¹

These biases create a gap between what is mathematically fair and what feels fair. Game designers live in that gap.

Why Designers Deliberately Bend the Rules

When a designer chooses to “lie” about RNG, they’re usually chasing a few key goals: perceived fairness, strong emotional arcs, and long-term engagement. Strategy games and story-forward titles aim to keep tension high without making players feel helpless.

Protecting Players From Statistical Cruelty

In any game with hit percentages, streaks are inevitable. A tactical mission can swing from victory to disaster on a handful of die rolls. For many players, that level of volatility crosses from exciting to infuriating. Even professional gambling operations work hard to manage how often customers experience devastating losses because feelings of unfairness push people away.²

By nudging probabilities after a streak of bad luck — or by slightly exaggerating how effective your actions are — designers can:

• Reduce the chance of catastrophic chains of failures.
• Preserve the fantasy that smart play is usually rewarded.
• Keep difficulty high while smoothing out the worst edges.

Serving Narrative and Emotional Beats

Games like Dispatch and other narrative-driven adventures also manipulate randomness to support pacing. A perfectly random system might produce:

• Two big story reveals back-to-back, leaving later sections flat.
• Long stretches with no dramatic events, boring the player.
• Sudden failures that undercut carefully scripted emotional scenes.

By layering soft rules over RNG — for example, “don’t spawn two major events within five minutes” or “never allow the player to fail at this particular moment” — designers use randomness as a tool for variety rather than a tyrant that dictates the story.

XCOM’s Approach: Visible Percentages, Hidden Help

XCOM is often cited in discussions of RNG because it confronts players with explicit hit percentages. When you see “95% to hit” on the screen and miss, your brain logs that as a betrayal.

To fight that reaction, some XCOM titles and similar strategy games implement systems often referred to as pseudo-RNG or compensation mechanics. The general idea (details vary by game and version) is:

• Each time you miss a high-percentage shot, your hidden chance improves for the next similar shot.
• Each time you hit an improbably low-percentage shot, the game might slightly reduce your odds next time to avoid unrealistic positive streaks.

Valve has described using pseudo-RNG in Dota 2 for similar reasons — to make chance-based procs, like critical hits, feel more consistent over time rather than extremely streaky.³ The core concept is identical: clamp the extremes so short-term experience matches human expectations for what randomness “should” look like.

How This Relates to Newer Narrative Games

While XCOM’s version is tactical and visible, a narrative game like Dispatch uses RNG to decide events, outcomes, and variations in dialogue. If such a game used pure randomness, players might hit:

• Runs where everything goes wrong, making the story feel frustrating rather than tense.
• Playthroughs where key content simply never appears.

To avoid that, a designer might quietly guarantee that certain critical beats happen in every run, or that sequences with many negative outcomes eventually give way to something more favorable. They’re not trying to deceive you maliciously; they’re curating your experience.

Common RNG Tweaks Developers Use

Here are several techniques developers apply to make RNG feel better than raw probability:

When Does RNG Feel Unfair?

Not all randomness is created equal. Players complain loudly when RNG crosses into a few problem areas:

Randomness That Overrides Skill

If a game’s outcome depends more on dice rolls than on the decisions you make, frustration builds quickly. Academic work on motivation and games has shown that people are most engaged when they feel their skills matter and their effort leads to progress.⁴ When RNG regularly nullifies smart play, the experience feels arbitrary.

Designers try to avoid this by:

• Increasing the number of rolls, so no single outcome decides everything.
• Letting skill influence the odds (e.g., better positioning = higher hit chance).
• Providing safety valves like partial success, chip damage, or fallback options.

Unclear or Misleading Information

Another fairness pitfall is poorly communicated odds. Some games display percentages that don’t match reality or fail to explain how modifiers work. That disconnect damages trust more than any single unlucky streak.

Compare two experiences:

• Transparent system: You miss a 65% shot, but you saw cover penalties and distance indicators, so you understand why.
• Opaque system: You miss several attacks with no clear explanation, and the UI never shows odds.

In the second case, even a very generous behind-the-scenes algorithm will feel unfair because you don’t know what rules you’re playing under.

Why Designers Sometimes “Lie” About Percentages

A more controversial tactic is displaying one probability while using a slightly different one internally. For example, the UI might say you have a 90% chance to hit, but the game could actually be giving you 93% or 95% to reduce feel-bad misses.

Developers take this risk for a few reasons:

• Consistency with human intuition: Players often expect fewer failures than real statistics allow, especially at high percentages.
• UI readability: Showing very granular odds (e.g., 93.6%) may clutter the interface and feel overly technical.
• Expectation management: Round numbers are easier to reason about, even if they’re not perfect representations.

This is likely what happens in some games that consciously follow in the footsteps of XCOM: they adopt both its clear percentage displays and some of its forgiving algorithms. To most players, the result feels more honest than strict accuracy because it matches how humans expect probability to behave.

Design Lessons from XCOM and Dispatch-Style Games

Taking inspiration from games that openly wrestle with RNG leads to a few practical guidelines for any system that relies on chance:

1. Expose Enough Information to Build Trust

Showing hit chances, loot odds, or at least qualitative descriptors (“unlikely,” “very likely”) helps players understand the stakes. When a miss happens at a high percentage, the blow is softened if the player knew they were taking a risk.

2. Use RNG to Add Texture, Not Chaos

Randomness should:

• Introduce variety from run to run.
• Create moments of surprise, both positive and negative.
• Force adaptation rather than following a solved script.

It should not repeatedly invalidate good choices or turn outcomes into a slot machine. Narrative games like Dispatch balance this by letting RNG color the details while keeping core story beats stable.

3. Smooth Extremes with Pseudo-RNG

If your game is prone to streaks that ruin sessions — like a tactical campaign where one mission gone wrong can snowball — consider using systems that:

• Track recent outcomes and adjust odds moderately.
• Guarantee success after a certain number of failures for key actions.
• Provide escalating consolation rewards when luck is bad.

Done well, this feels like a generous universe rather than a rigged one.

4. Decide How Honest You Need to Be

There’s an ethical and aesthetic question at the heart of RNG manipulation: should designers reveal exactly how the numbers work? Different genres answer differently:

• Competitive PvP games lean toward strict, transparent math to protect competitive integrity.
• Single-player strategy and narrative games have more freedom to cheat in the player’s favor for the sake of drama and pacing.

Borrowing the XCOM-style approach makes the most sense when the goal is an evocative story of close calls and hard-won victories, not a lab-grade simulation.

FAQs About RNG and Hidden Game Mechanics

Does every game cheat its RNG?

No. Many games, especially competitive titles and roguelikes with a hardcore audience, stick to pure or near-pure randomness. Others selectively adjust specific systems (like critical hits or loot drops) while leaving the rest untouched.

Is it unethical for developers to change odds behind the scenes?

It depends on context and expectations. If a game sells items based on stated percentages (for example, regulated loot boxes), then accuracy and transparency are critical. In single-player experiences where RNG manipulation primarily makes the game more enjoyable, players often accept or even prefer subtle behind-the-scenes adjustments.

Why do I remember bad RNG more than good luck?

This stems from well-known psychological effects like negativity bias: we pay more attention to negative outcomes than positive ones, especially when they impact our goals or sense of control.¹ That’s why a single missed 95% hit sticks in your memory more than a long run of expected successes.

How can I tell if a game is using pseudo-RNG?

Short of reading developer documentation or digging through the game’s code, you can only infer it from behavior. If your hit rate over many attempts seems closer to the stated percentage than streaky intuition would suggest — or if failure chains mysteriously “break” — the game may be smoothing outcomes.

Should designers show or hide fail-streak protection?

Opinions differ. Some designers worry that exposing it will make systems feel fake, while others think transparency is always better. A middle path is to describe the philosophy in patch notes or interviews (“we reduce long streaks of bad luck”) without publishing exact formulas.

Final Thoughts: When the Game Is on Your Side

From XCOM’s tactical firefights to story-focused games like Dispatch, modern design often treats randomness as a raw ingredient, not a finished product. The pure output of a random number generator rarely aligns with how humans expect chance to behave or with the kind of emotional journeys games aim to deliver.

By bending probabilities — sometimes even fibbing a little about them — designers protect players from the worst cruelties of statistics while preserving the thrill of uncertainty. The next time you land a clutch shot at 30% or survive a tense encounter by a hair’s breadth, remember: the universe might be rigged in your favor, and that might be exactly what makes the story worth telling.
