What Candy Crush and similar games do to your brain
Candy Crush, Candy Saga, and games like them are designed to keep you playing longer than you intend. They use patterns that trigger the same reward centers in your brain that respond to gambling or shopping. Each level you pass releases a small amount of dopamine — the chemical that makes you feel accomplished — which makes you want to play "just one more level."
The games are free to read, but they make money by slowing you down. After a certain number of moves, you run out of "lives" and must wait 30 minutes to play again, or pay real money to continue when ready. This wait is intentional. It creates frustration that makes paying feel like relief rather than spending.
For seniors, this matters because the games are designed by teams of psychologists and data scientists whose job is to figure out exactly how long to make you wait and how much to charge before most people will pay. You are not weak-willed if you spend more than you planned — you are playing against professionals who study human behavior for a living.
Key Takeaways
- Candy Crush and similar games use wait times and small payments to generate revenue, not because the game needs the money to run.
- The games are designed to trigger reward patterns in your brain similar to gambling, making it hard to stop at a planned stopping point.
- Most players who spend money on these games spend between $5 and $20 per month, but some spend far more without realizing it.
- Setting spending limits before you play, not during, is more effective than trying to control yourself while playing.
- Turning off in-app purchases entirely in your phone settings prevents accidental or impulsive charges.
How the money mechanics work
When you run out of moves on a level, the game offers you three choices: wait 30 minutes, watch an advertisement (usually 30 seconds), or pay $0.99 to $4.99 to continue now. The prices are small enough that they feel harmless, and the game does not show you a running total of what you have spent in a session or a month.
Some games also sell "boosters" — temporary power-ups that make levels easier. These cost money and are often presented as the only way to pass a particularly hard level. In reality, the levels are designed to be passable without boosters, but the game makes boosters seem necessary by making the level extremely difficult without them.
The games also use "events" — limited-time challenges that offer rewards for spending money during a specific week. These create urgency and make spending feel like you are taking advantage of a special offer rather than paying for the same game you played yesterday.
How much people actually spend
Most people who pay anything on Candy Crush spend between $5 and $20 per month. Some spend nothing. A small percentage spend $50 to $100 or more per month without realizing it, because each individual purchase feels small and the game does not remind you of your total.
The game tracks your spending in your app store account (Apple App Store or Google Play), not in the game itself. To see how much you have spent, you have to leave the game and check your account settings. This separation is intentional — it makes it easier to spend without thinking about the total.
If you have a grandchild or family member with access to your phone or tablet, they can also make purchases. Many accidental charges happen this way. A child taps what looks like a free reward and accidentally buys a booster pack.
How to set limits before you play
The most effective way to control spending is to turn off in-app purchases entirely before you start playing. On an iPhone, go to Settings, then Screen Time, then Content & Privacy Restrictions, then iTunes & App Store Purchases, and set In-App Purchases to "Don't Allow." On an Android phone, go to Google Play Store, tap your profile icon, then Payments and Subscriptions, then Manage Payment Methods, and remove any saved payment methods.
If you want to allow some spending but set a limit, you can instead set a spending cap. On iPhone, go to Settings, then Screen Time, then App Limits, and set a daily limit for the game itself. This does not prevent purchases, but it locks you out of the game after a certain amount of time each day. On Android, you can set a monthly spending limit in Google Play by going to Settings, then Family, then Parental Controls.
Another approach is to use a separate device for games — an old tablet or phone that is not connected to a payment method. This way, you can play for free (with ads and wait times) without any way to accidentally spend money.
Why these games are hard to quit
Candy Crush and similar games use a technique called "variable reward scheduling." This means you do not know when you will win. Sometimes you pass a level on your first try. Sometimes it takes 20 tries. This unpredictability is more addictive than a game where you always know what will happen, because your brain keeps hoping the next try will be the lucky one.
The games also use "near-miss" design. Levels are often set up so that you almost win but fall just short. This makes you want to try again when ready. If you had lost by a lot, you might walk away. But losing by one move makes you feel like you were close, which makes you want to spend money on a booster to try again.
The games also send you notifications. "You have a free life!" or "Your friends are playing!" These are designed to pull you back in during moments when you were not thinking about the game. Turning off notifications in your phone settings can help break this cycle.
What to watch for if you play regularly
If you play Candy Crush or a similar game several times a week, check your app store account once a month to see what you have actually spent. Many people are shocked when they add it up. A few dollars here and there adds up to $50 or $100 over a few months without you noticing.
Watch for signs that the game is affecting your sleep, your mood, or your relationships. If you are playing late into the night, getting frustrated when you lose, or choosing to play instead of spending time with family, those are signs that the game has moved from entertainment to something that is taking up too much of your life.
If you notice charges on your credit card or bank statement that you do not remember making, contact your app store when ready. Both Apple and Google have processes to dispute charges and get refunds for accidental purchases. You have a better chance of getting a refund if you report it within 30 days.
Free games that do not use these tactics
If you enjoy puzzle games but want to avoid the spending pressure, some games charge a one-time fee upfront instead of using wait times and in-app purchases. These games are less common in app stores because they make less money, but they exist. Look for games labeled "premium" or "paid" rather than "free."
Some games are truly free with no spending option at all. These are usually older games or games made by smaller developers. They may have fewer features or less frequent updates, but they will not pressure you to spend money.
Puzzle games that are not on phones — board games, card games, or books of crosswords and sudoku — offer the same mental engagement without any spending pressure or time limits. Many libraries have free puzzle books you can borrow.
Frequently Asked Questions
Is it safe to give my credit card information to these games?
Your credit card information goes to Apple or Google, not to the game itself. Both companies have fraud protection. However, if you do not want to risk any charges at all, do not store a payment method on your device. Use a device with no payment method attached, or turn off in-app purchases in your settings.
Can I get a refund if I spent money by accident?
Yes. Contact Apple Support or Google Play Support within 30 days of the charge and explain that the purchase was accidental. They grant refunds for accidental in-app purchases fairly often, especially if it is your first request. After 30 days, refunds are harder to get.
Why does the game get harder the longer I play?
The game adjusts difficulty based on how much you are spending. If you are not spending money, levels get harder to encourage you to buy boosters. If you are spending regularly, levels stay easier so you keep playing and keep spending. This is called "dynamic difficulty" and is built into the game's code.
What should I do if a family member is spending too much on these games?
Have a conversation about the spending without judgment. Explain how the games are designed to encourage spending. Then work together to turn off in-app purchases or set up a device without payment methods. If the person is an adult, you cannot force them to stop, but you can help them understand what is happening.
Are these games actually bad for my brain?
Playing puzzle games is good for your brain — it keeps your mind active and engaged. The problem is not the puzzle part, it is the spending pressure and the design that makes it hard to stop. A puzzle game that does not use wait times or in-app purchases is genuinely good for you. A game that uses these tactics is designed to take your money, not to help you.
