Video game creators have long grappled with a core reality: pure randomness often feels unfair to players, even when the odds are mathematically in their favor. XCOM’s legendary designer Jake Solomon solved this problem by subtly manipulating probability calculations behind the scenes, increasing how often players succeed without anyone noticing. Now, the developers of Dispatch, a superhero comedy game from AdHoc Studios, have adopted the same psychological trick for their dispatching minigame. At a recent Game Developers Conference talk, directors Nick Herman and Dennis Lenart explained how they drew from XCOM’s odds-adjusting method to make their game feel fair while secretly tilting things in players’ favor—a strategy that prevents frustration from undermining the experience, even if the math doesn’t fully add up.
The Study Underlying Unfair Fairness
The fundamental problem that both XCOM and Dispatch address is strikingly unintuitive: true randomness doesn’t seem random to players. When a 95% success chance falls through, players don’t think “well, that’s the five percent.” Instead, they assume the game is cheating against them. This disconnect between mathematical reality and human perception has haunted game designers for years. Players want fairness, but they measure fairness through their subjective feelings rather than mathematical precision. A run of unfortunate outcomes, even if entirely valid, produces the sensation that the game is fixed. This psychological bias is so powerful that developers have learned to embrace it rather than oppose it.
Adhoc’s approach was well-designed: acknowledge that players need reassurance more than they require genuine unpredictability. By guaranteeing success on anything above 76%, the developers stripped away the most frustrating edge cases while preserving the illusion of genuine probability. The system then adapts based on player performance, taking away the safety net after three straight victories and reinstating it after a defeat. This generates a dynamic difficulty curve that feels fair because it stops both consecutive wins and defeats from growing frustrating. The genius exists in giving players a sense of agency while the game quietly manages their emotional state through invisible probability adjustments.
- Deliver success rates exceeding 76% to eliminate frustrating near-misses
- Eliminate safety mechanism following three consecutive player wins
- Reactivate automatic success following any failure exceeding 76%
- Adjust low-probability events separately for even difficulty
The Dispatch Hidden Success Mechanics
The 76 Percent Assurance
Dispatch implements a surprisingly straightforward rule at its foundation: any assignment with a likelihood of success above 76% is assured of success. This threshold isn’t arbitrary—it’s precisely tuned to eliminate the most frustrating instances of frustration without making the game trivial. By automatically succeeding on high-confidence assignments, Adhoc ensures that players who make smart tactical decisions are rewarded immediately, rather than punished by unlikely dice rolls. The threshold creates a mental safety space where players believe their tactical decisions will pay off more often than not.
What gives this system especially clever is its hidden nature. Players fail to notice the safety net catching them; they just encounter fewer severe failures on decisions they confidently made. This preserves the appearance of real probability while shielding players from the unusual patterns that would otherwise feel like letdowns. The 76% cutoff represents the sweet spot between maintaining substantial risk and avoiding the kind of momentum-killing failures that make players question the game’s fairness.
Safeguarding Against Losing Runs
The system becomes even more sophisticated when handling player momentum. After three straight successful assignments, Dispatch removes the automatic success guarantee and pushes players back into actual probabilities. This stops the game from seeming too easy once players reach a winning streak. However, the moment a player struggles on a mission with over 76% success chance, the safety net instantly kicks back in. This establishes a dynamic equilibrium that prevents both runaway success and brutal losing runs from dominating the experience.
The appeal of this strategy lies in its imbalance. Players never experience prolonged stretches of unfavorable outcomes because the system steps in to reestablish equilibrium. Conversely, players can’t exploit the system by building unstoppable winning streaks. The underlying system constantly modifies difficulty to sustain player interest, ensuring that no individual result—victory or failure—feels like it’s moving outside the player’s control or ability.
- Three consecutive victories activate return to actual odds
- One unsuccessful attempt exceeding 76 percent immediately restores guaranteed success guarantee
- System dynamically equilibrates winning and losing streaks dynamically
Creating a Well-Proportioned Challenge Progression
Dispatch’s probability manipulation represents a carefully considered design strategy that prioritizes player satisfaction over pure mathematical fairness. By implementing invisible guardrails, Adhoc guarantees planned moves feel acknowledged regularly without crossing into trivial territory. The system acknowledges a basic principle about game design: players prioritize less true randomness than they do about believing their selections have impact. When a player strategically picks characters matched with a task’s obstacles, they expect success more often than not. Dispatch fulfills that promise through refined numerical tweaks that reinforce the connection between smart planning and positive outcomes.
This method changes what could be aggravating chance mishaps into moments that strengthen player autonomy. Rather than penalizing thoughtful choices with unexpected failures, the game subtly guarantees that carefully planned approaches work out. The designers recognized that conventional chance mechanics produces emotional conflict—players retain the high-probability miss far more intensely than the dozen successful 60% assignments. By dampening the extremes, Dispatch sustains dramatic stakes and player choice while eliminating the kind of chance-based disappointments that leave players feeling robbed by the system.
| Success Range | Game Behavior |
|---|---|
| 76% and above | Automatically succeeds (until three consecutive wins) |
| 15% to 75% | True probability odds apply without modification |
| 1% to 14% | Automatically fails to prevent unlikely catastrophes |
| After losing streak | Three auto-wins granted to restore player confidence |
When Training Wheels Come Off
Dispatch’s chance mechanics isn’t designed to coddle players indefinitely. After three straight winning missions, the game takes away the training wheels and exposes players to true randomness for the very first time. This moment marks a subtle shift in difficulty that many players might not actively notice, yet it fundamentally changes how the game feels. The transition occurs silently, without fanfare or notification, allowing seasoned players to discover that their luck has shifted. This creative decision respects player competence by assuming that after a few victories, they’ve gained sufficient experience to handle genuine uncertainty.
The system restores its guardrails the moment a player experiences a loss above 76% odds, quickly granting three automatic wins to prevent severe downturns. This creates a adaptive challenge system that reacts to player outcomes in real time, tightening or loosening its grip based on real results rather than fixed challenge levels. It’s a sophisticated balancing act that understands players want both challenge and reassurance. The game effectively poses: are you willing to face the actual chances, or do you want the support back on? The answer is always merely one defeat away.
- Three consecutive victories trigger removal of automatic success guarantees
- Any failure above 76% immediately reactivates safety features
- System adapts difficulty according to performance patterns
Why Gamblers Fail to Detect the Exploitation
The brilliance of Dispatch’s odds structure exists in its invisibility. Players experience what seems like genuine randomness because the manipulation occurs at the extremes—the instances when true chance would appear most unfair. When a player sees a 95% likelihood of success and it fails, they’re annoyed by what appears to be bad luck rather than doubtful about the game’s mechanics. Conversely, when they try a 10% chance mission and it surprisingly succeeds, they take pride in their boldness rather than challenge the odds. By preserving the middle range of probabilities genuine, Dispatch upholds the illusion of fairness while safeguarding players from the worst statistical outcomes.
This psychological trick works because players rarely analyze the data behind their experiences. They fail to monitor success rates across numerous campaigns or detect trends in when the game appears to manipulate outcomes. Instead, they remember the dramatic moments—the last-minute triumphs and crushing defeats—which feel justified or chance-based rather than engineered. The system honors player autonomy by only intervening when odds grow unrealistic, making the manipulation feel like chance rather than intention. It’s a lesson that sometimes the best game design is the kind players don’t actively notice, only feel.
