You’ve definitely had this experience: Pick up your phone planning to play Candy Crush or Merge Dragons! for just 5 minutes, but when you look up, an hour has quietly passed. Even though you know repetitive tapping and matching actions are meaningless, you still can’t help swiping the screen—even if your fingers ache and your eyes feel dry, you just can’t stop.
Many people attribute this “loss of control” to “weak willpower,” but the truth is far more complex. The reason we can’t get enough of minigames is essentially that our brains are accurately manipulated by minigame designers, who gradually pull us into a carefully crafted “dopamine trap.” Dopamine, this brain messenger often mistaken for a “pleasure hormone,” is the core code that makes minigames addictive. Today, we’ll break it down layer by layer to see how minigames manipulate dopamine and make us willingly “succumb.”

First, Clarification: Dopamine Is Not a “Pleasure Hormone”—It’s a “Messenger of Expected Rewards”
Before we uncover the truth, let’s correct a common misunderstanding: Dopamine ≠ pleasure. Many people think that the more dopamine is secreted, the happier we are, but neuroscientific research shows that dopamine’s core function is to “predict and anticipate rewards,” not to directly produce pleasure.
There is a “dopamine reward pathway” in the brain, originating from the ventral tegmental area (VTA) and extending to regions such as the nucleus accumbens (NAc) and prefrontal cortex. The nucleus accumbens is responsible for receiving “reward signals,” the prefrontal cortex judges the value of rewards and controls behavior, and dopamine is the messenger that transmits “rewards to anticipate” along this pathway.
For example, when you see a bowl of hot rice when you’re hungry, your brain secretes dopamine in advance, telling you “eating this bowl of rice will satisfy you” and motivating you to eat. When you finish a task and receive praise, dopamine starts to secrete even before the praise comes, reinforcing the perception that “hard work pays off.” Under normal circumstances, dopamine secretion is moderate; it motivates us to pursue valuable goals such as studying, working, and exercising, keeping us in a positive state.
But the terrifying thing about minigames is that they break the normal pattern of dopamine secretion. Through a series of elaborate designs, they keep the brain in a state of “high expectation and high reward,” eventually making the dopamine reward pathway “sensitive and greedy” and forming an addictive cycle. The underlying logic of all this was revealed decades ago by psychologist B.F. Skinner’s classic experiment.
Key Experiment: Skinner’s “Superstitious Pigeons” Hides the Nature of Minigame Addiction
In 1948, behaviorism master B.F. Skinner conducted an influential experiment—the “superstitious pigeons” experiment. This experiment perfectly replicates the core mechanism that makes minigames addictive and explains why we are so obsessed with “unpredictable rewards.”
Skinner placed 8 hungry pigeons in separate “Skinner boxes.” The food dispenser in each box was set to drop one pellet every 15 seconds, regardless of what the pigeon was doing at the time. In other words, the pigeons received food unrelated to any of their behaviors—a phenomenon known in psychology as “non-contingent reinforcement,” where rewards appear randomly and unpredictably.
After a few days of the experiment, a magical phenomenon occurred: 6 out of the 8 pigeons developed unique “signature behaviors,” as if these actions could “summon” food. One pigeon repeatedly turned counterclockwise, making 2-3 turns between feedings; one always stretched its head toward the corner above the box, as if “begging”; others raised their wings, shook their heads and tails, or even performed movements similar to “dancing.”
These behaviors had never appeared before the experiment, and the truth is: the food dropped automatically at fixed intervals, completely unrelated to the pigeons’ actions. But by chance, the pigeons found that when they performed a certain action, food happened to drop. The reward of food reinforced that action—they firmly believed that their behavior had brought the reward, so they repeated it continuously and gradually became “superstitious.”
More surprisingly, when Skinner stopped dropping food pellets, these “superstitious behaviors” did not disappear immediately: the most stubborn pigeon repeated its “dancing” action more than 10,000 times before it gradually faded. Skinner’s conclusion was clear: when rewards are random and unpredictable, animals (including humans) will repeat a certain behavior more frequently because the brain continuously secretes dopamine, anticipating the next “accidental reward.”
Minigames, in essence, are a “digital Skinner box.” Just like those pigeons, we are manipulated by “random rewards,” repeatedly performing simple actions such as tapping and swiping. What drives us is the continuous secretion of dopamine in the brain. Subsequent research further confirmed that the amount of dopamine secreted by random rewards is much higher than that by fixed rewards. When rewards are predictable, the brain gradually adapts and dopamine secretion decreases; but when rewards are unpredictable, the brain remains in a state of high expectation, and dopamine stays at a relatively high level, making us more and more addicted—even 5-10 times more attractive than fixed rewards.
Breaking It Down: 4 “Precise Tactics” Minigames Use to Manipulate Dopamine
If “random rewards” are the core of minigame addiction, minigame designers also use 4 precise tactics to amplify dopamine’s effect, making the “trap” more hidden and harder to escape. Each of these tactics accurately hits the brain’s weaknesses, making us unknowingly “kidnapped” by dopamine.
Tactic 1: Instant Feedback, Making Dopamine “Secrete in Seconds”
The brain is extremely sensitive to “instant feedback,” and the core design principle of minigames is “tap and get feedback, operate and get rewards,” allowing dopamine to secrete in an instant and bring immediate satisfaction.
For example, in Candy Crush, when you tap two identical candies, they disappear immediately, accompanied by a “Match Successful” prompt, a crisp sound effect, and even screen shaking (vibration) and instant frame pauses. These seemingly simple feedbacks are actually sending a signal to the brain: “You’re doing well, there’s a reward.” Dopamine secretes the moment you tap, giving you a “pleasurable rush” and making you unable to resist tapping the next candy.
Another example is Merge Dragons!: when you tap two low-level items, you can instantly merge them into a high-level item. The item’s appearance and special effects upgrade immediately, and you may even get a “Merge Successful! Rare Item Obtained” prompt. This “instant feedback” allows the brain to get “reward signals” without waiting, keeping dopamine in a low-level excited state. Every tap is a small “dopamine rush.”
In real life, however, any valuable thing we do requires waiting for feedback: studying hard takes months to see results; working hard takes years to get a promotion; sticking to exercise takes weeks to see changes. This “delayed feedback” makes dopamine secretion in the brain weak, so it’s naturally difficult to get the same immediate satisfaction as from minigames—which is why many people subconsciously open minigames to seek “quick dopamine supplements” when they feel tired or bored in reality.
Tactic 2: Random Rewards, Making the Brain “Always Anticipate the Next One”
This is the most core and effective tactic minigames use to manipulate dopamine, and it’s also the core logic of Skinner’s “superstitious pigeons” experiment. Minigames deliberately design “unpredictable rewards,” making it impossible for the brain to predict what it will get with the next tap, thus continuously secreting dopamine and maintaining high expectation.
For example, the “lottery system” in many minigames: you spend a few in-game items to draw a prize, and you may get ordinary items, rare items, or even worthless junk. It’s this “uncertainty” that keeps the brain in a state of “expectation” and dopamine continuously secreted. Even if you draw junk several times in a row, your brain will tell you “maybe you’ll get a rare item next time,” motivating you to keep drawing—just like those pigeons that kept dancing, firmly believing “one more dance will bring food.”
Another example is the “critical hit reward” in Candy Crush: normally, matching candies only gives you 10 points, but occasionally you’ll trigger a “critical hit” and get 100 or even 1000 points. In Merge Dragons!, there’s “lucky merge”: occasionally, a single tap can merge into a high-level item far beyond expectations. This “accidental surprise” makes dopamine surge instantly, bringing a stronger sense of satisfaction than ordinary rewards. This satisfaction reinforces your “continue tapping” behavior—you’ll always anticipate the next “critical hit” and pursue the next “surprise,” unable to stop.
More subtly, minigames deliberately control the “probability of random rewards”: they won’t let you draw rare items all the time (otherwise the reward will become predictable and dopamine will decrease), nor will they let you draw junk all the time (otherwise you’ll give up). Instead, they adopt a model of “occasional big wins and frequent small rewards,” keeping the brain always expecting “one more try.” This is the so-called “intermittent reinforcement”—a reinforcement method that makes behaviors extremely persistent. Even if you know the reward probability is low, you can’t help but keep trying, which is why many people are addicted to the lottery and treasure chest functions in minigames.
Tactic 3: Fragmented Design, Making Dopamine “Activable Anytime”
Another fatal design of minigames is “fragmentation”—no need to download large clients; you can play them directly in WeChat, TikTok, or other apps. A single game only takes 1-3 minutes, so you can play a round even in fragmented time such as queuing, waiting for the bus, or taking a short break at work. This design lowers the “activation threshold” of dopamine to the minimum, allowing us to get dopamine satisfaction anytime, anywhere.
The brain has no resistance to “easily obtainable rewards.” For example, when you’re queuing for the bus and feeling bored, your brain will subconsciously seek stimulation. At this time, opening Candy Crush and playing a round in just 1 minute can give you instant feedback and dopamine satisfaction, which is more “efficient” than scrolling through short videos—scrolling requires passively accepting content, while playing minigames allows active operation, bringing a stronger sense of “control” and “reward,” and more obvious dopamine secretion.
More importantly, fragmented gameplay makes us form a “habitual tap”: whenever we have free time, we subconsciously open minigames and play one or two rounds—even just a few minutes can supplement the brain’s dopamine. Over time, this “habitual tap” becomes a conditioned reflex, just like we subconsciously check our phones when they light up. Playing minigames becomes an instinctive behavior without thinking, and addiction is inevitable.
At the same time, minigames use “multimodal feedback” to strengthen this habit: the “click” sound when tapping, the vibration feedback when getting a critical hit, the visual gradient effect when leveling up. These multiple stimuli of hearing, touch, and vision make the brain more sensitive to the “reward signals” of minigames. Even just hearing the sound of a minigame will make dopamine secrete in advance, motivating us to open the game.
Tactic 4: Goal Breakdown + Progress Visualization, Keeping Dopamine “Secreting Continuously”
Minigames break down a seemingly distant “big goal” into countless simple and achievable “small goals.” At the same time, they make progress visible through progress bars, levels, badges, and other methods. This design keeps the brain in a state of “having expectations and being able to achieve them,” allowing dopamine to secrete continuously and motivating us to complete goals step by step until we become addicted.
For example, the “level design” in Candy Crush: the goal of each level is very simple, such as “match 10 red candies,” “reach 500 points,” or “pass in 30 seconds.” These small goals are easy to complete, and after completion, you can immediately unlock the next level and get rewards such as badges and in-game items. In Merge Dragons!, there’s the “level design”: every time you merge an item, you get experience points. When the experience points accumulate to a certain level, you level up, unlocking new items and new scenes, so you always have new goals to pursue.
Neuroscientific research shows that when goals are clear and achievable, the brain continuously secretes dopamine, motivating us to complete them; when goals are vague and difficult to achieve, dopamine secretion decreases, and we are more likely to give up. The goal breakdown design of minigames precisely hits this point—completing each small goal is a “reward,” and dopamine secretes the moment you complete the goal, giving you a sense of accomplishment of “I can do it,” while making you anticipate the completion of the next small goal, forming a cycle of “complete a goal → secrete dopamine → anticipate the next goal.”
More cleverly, minigames deliberately design “almost there” scenarios: for example, in Candy Crush, you’re one candy away from passing the level. At this time, the brain secretes a lot of dopamine, telling you “just a little more effort to get the reward,” motivating you to keep playing. Or in Merge Dragons!, you’re one fragment away from merging a rare item, and the brain remains in a state of high expectation, making you unable to resist tapping until you merge it successfully. This “almost there” design maximizes dopamine secretion, and it’s also the key reason why many people say “just one more round” but end up playing countless rounds.
Warning: Long-Term Addiction Will Make Dopamine “Malfunction”
Playing minigames for a few minutes occasionally to relieve stress and get a little dopamine satisfaction is not a bad thing in itself. But if you become addicted for a long time, irreversible changes will occur in the brain’s dopamine reward pathway, eventually making dopamine “malfunction” and trapping you in a vicious cycle of “the more you play, the emptier you feel; the emptier you feel, the more you play”—this is the ultimate harm of the dopamine trap.
Playing minigames for a long time keeps the brain in a state of high dopamine. To adapt to this high-intensity stimulation, the brain activates a “self-protection” mechanism: it reduces the number of dopamine receptors (also known as dopamine receptor desensitization and downregulation), making the brain less sensitive to dopamine. Just like long-term medication leads to “drug resistance,” the brain needs more dopamine to achieve the same sense of satisfaction as before.
As a result, you’ll find that at first, playing for 10 minutes can make you feel satisfied, but later you need to play for 30 minutes or an hour to get the same feeling. At first, playing simple levels can make you happy, but later you need to challenge harder levels and draw more prizes to get a little satisfaction. What’s more terrifying is that when you leave minigames and return to real life, you’ll find that you’re not interested in anything—studying, working, exercising, even hanging out with friends can’t make the brain secrete enough dopamine, because the “rewards” in real life are far less stimulating than those in minigames.
At this time, you’ve fallen into the dopamine trap: minigames have become your only way to get dopamine. You can’t live without them, but you feel deep emptiness and guilt after playing. You want to quit, but because of the brain’s “craving” for dopamine, you can’t help but pick up your phone again and again—this is not weak willpower, but the brain’s neural pathways have been changed, forming a double dependence on physiology and psychology. Just like those pigeons in Skinner’s experiment that kept dancing even without food, you’re trapped in an inescapable “superstitious cycle.”
How to Escape the Dopamine Trap? 3 Simple and Practical Methods
Understanding how minigames manipulate dopamine, we no longer have to blame ourselves for “being addicted”—addiction is not your fault; it’s just that minigame designs are too precise and the brain’s weaknesses are too obvious. But this doesn’t mean we can only surrender. As long as we master the correct methods, we can take back control of our brains and escape the dopamine trap.
Method 1: Set Limits on Minigames to Break the “Instant Feedback Cycle”
Since the core of minigames is “instant feedback + playable anytime,” we need to start with “limiting time and scenarios” to break the cycle of continuous dopamine secretion. For example, only allow yourself to play minigames for 10 minutes a day, set a timer on your phone, and close the game immediately when the time is up—never procrastinate. Or only allow yourself to play during fragmented time such as queuing or waiting for the bus, not at home, at work, or while studying, to avoid forming “habitual taps.”
At the same time, we can deliberately “delay feedback”: for example, when you want to play minigames, force yourself to do something else for 5 minutes first (such as drinking water, stretching, or reading a few pages of a book) before playing. This helps the brain gradually adapt to the state of “not getting rewards immediately” and reduces the excessive craving for dopamine.
Method 2: Replace Minigames’ “False Rewards” with “Valuable Goals”
The rewards minigames give us are “false”—they can only bring short-term dopamine satisfaction, but cannot improve our quality of life or help us achieve real growth. The key to escaping the trap is to replace these false rewards with “valuable goals,” allowing dopamine to return to its essence: motivating us to pursue meaningful things.
For example, you can set some simple and achievable small goals for yourself: read 10 pages of a book a day, exercise for 15 minutes a day, or learn one new knowledge point a day. Like the small goals in minigames, these goals are simple and achievable. After completing them, you can get a real sense of accomplishment—this sense of accomplishment will make the brain secrete an appropriate amount of dopamine, and the satisfaction brought by this dopamine is far more lasting and valuable than that from minigames.
At the same time, you can set “progress visualization” for these goals just like minigames do: for example, use a notebook to record your daily learning progress, use a fitness app to track your daily exercise time, or reward yourself with badges. This keeps the brain in a state of “having expectations and being able to achieve them,” making dopamine a driving force for our growth rather than a chain of addiction.
Method 3: Do More “Low-Stimulation, High-Reward” Things to Repair the Dopamine Pathway
Long-term addiction to minigames makes the brain dependent on “high stimulation” and lose interest in “low stimulation.” Therefore, we need to deliberately reduce “high-stimulation” input (such as playing fewer minigames and scrolling through fewer short videos) and do more “low-stimulation, high-reward” things to help the dopamine pathway return to normal.
For example, reading, writing, painting, gardening, chatting face-to-face with friends, walking, and meditating—these things may not have the instant feedback and strong stimulation of minigames, but they can bring lasting satisfaction and happiness. Moreover, they can make the brain’s dopamine secretion return to a moderate state and repair the overstimulated dopamine receptors.
It should be noted that repairing the dopamine pathway takes time—maybe a few weeks or even a few months. During this process, you may feel bored, irritable, or want to play minigames—this is normal, because the brain is adapting to the “low-stimulation” state. At this time, be patient with yourself and don’t blame yourself for occasional “slip-ups.” As long as you persist, you’ll gradually find that your craving for minigames becomes weaker and your interest in real life becomes stronger.
Finally: Minigames Are Not Guilty—The Key Is to Control Our Brains
In the end, minigames themselves are not a scourge. Their essence is a form of entertainment—a “tool for instant happiness” created by designers using neuroscientific and psychological principles. And dopamine is not a “bad thing”; it’s a “source of motivation” given to us by the brain, which can motivate us to pursue valuable goals.
The core reason minigames are addictive is never “the games are too fun,” but that they accurately manipulate the law of dopamine secretion, taking advantage of the brain’s instinct to “anticipate rewards” and its preference for “instant feedback” and “random surprises,” gradually pulling us into the trap. The key to escaping the trap is not to “quit minigames,” but to “take back control of our brains”—understand the truth about dopamine, see through the design logic of minigames, and use reason and patience to let dopamine return to its essence, so that entertainment serves our lives rather than kidnapping our lives.
Next time, when you can’t help but open a minigame, stop and think: it’s not that I have weak willpower, but that my brain is anticipating dopamine rewards; it’s not that I want to play, but that the minigame is manipulating my brain. When you see this clearly, you’ve already taken the first step to escape the dopamine trap.
