Mobile gaming has long gone beyond a simple pastime, turning into a complex industry with an internal economy, where resources often have real value. Many users, faced with the impossibility of passing a difficult level or wanting to try out the mechanics without long grinds, think about how to change the value in the game on Android. This could be an increase in the amount of gold, a change in the character's health, or an adjustment of experience points to speed up pumping.
The process of modifying game data is based on the principle of operation of the device's RAM. When you run the application, it loads variables (numeric values of health, currency, ammo) into RAM, assigning them specific addresses. Memory editor is a specialized tool that scans the memory sector allocated to the process, finds the desired value and allows you to replace it with another. However, modern data protection and encryption systems make this process not always trivial.
It is worth immediately noting that changing local variables in online games with server-based authorization verification (MMORPG, ranked shooters) is most often useless or leads to account blocking. In such projects, critical data is stored on a remote server, not on your device. However, for offline projects and simulators, this method remains the main way to gain an advantage or learn mechanics.
The principle of memory operation and types of values
Before you begin practical actions, you need to understand how the computer represents numbers. In the device memory, data is stored in binary form, and each value occupies a certain number of bytes. Data Type determines how many bytes are allocated for the number and how it is interpreted. An error in selecting a type during a search may result in you either not finding the cell you need, or changing an adjacent parameter, which will cause the application to crash.
The most common type is Double Word (32 bits or 4 bytes), which is used to store most integers in games. For very large numbers exceeding the range of a 32-bit system, QWord (64 bits) is used. If you are working with fractional numbers, for example, exact coordinates or health percentages with tenths, you should look in the format Float or Double.
There is also the concept of a “frozen” value. When you change a number in memory, the game may overwrite it back in a split second if the value is controlled by an internal timer or counter. In such cases, the editors offer a “freeze” function, which forcibly holds the value at the selected address, preventing the game from updating it. This is especially useful for infinite health or ammo.
- 🔢 Integer (DWord): standard type for integers, used 90% of the time for currency and points.
- 📐 Float/Double: data types for floating point numbers, needed to find coordinates or health with a fractional part.
- ❄️ Freeze: force-fixing function to prevent outsiders from changing it game engine.
⚠️ Attention: Trying to change string data (text) or complex structures without understanding offsets is almost guaranteed to lead to unstable operation of the application. Always start with simple numeric variables.
Required tools and device preparation
To successfully modify game data, standard Android tools are not enough. The operating system isolates application processes from each other, and one app cannot just “crawl” into the memory of another without special permissions. Therefore, the first step is to obtain advanced access rights, known as root access. Without them, the functionality of editors will be severely limited, allowing you to work only with applications running in an emulator or through special virtual environments.
The most popular and powerful tool today is GameGuardian. This utility supports many processor architectures (ARM, x86, x64) and can work with various number formats. An alternative could be Cheat Engineported to Android, but it often requires a USB connection and the use of ADB commands, which is less convenient for the mobile platform. There are also simpler editors tailored for specific games, but they are less universal.
If obtaining superuser rights on the main device is impossible or undesirable due to the risk of losing the warranty, you can use Android emulators on a PC, such as NoxPlayer or LDPlayer. In them, root access is often enabled by default or activated in the settings. For real devices, there are also virtual spaces (for example Parallel Space with plugins or VMOS), which create an isolated environment with root access already built-in, allowing you to run memory editors inside this "bubble".
It is important to ensure system stability. Before starting, it is recommended to close all background applications to free up RAM and speed up the scanning process. It is also worth checking if the power saving mode is turned on, as it can limit the background activity of the memory editor, interrupting the process of searching for values.
Step-by-step guide: searching and replacing values
The process of changing a value in the game is based on a sequential search refinement algorithm. Since there may be millions of cells in the memory of a running application with a value, for example, "100", we need to filter out the unnecessary ones. We use the "elimination" method, changing the value in the game and telling the editor what to look for now.
First, start the game and get to the point where the target value (for example, the number of coins) is visible. Then, without closing the game, activate the memory editor. Select the desired game from the list of processes. If there are several processes with a similar name, choose the one that consumes the most memory. In the search field, enter the current value and click "New Search", selecting data type Auto or DWord.
1. Start the game and remember the value (for example, 500 gold).2. Open GameGuardian and select the game process.
3. Enter 500 in the search field and click Start.
4. Return to the game and spend some of the gold (for example, buy an item for 100).
5. In the editor, enter a new value (400) and click “Refine”.
6. Repeat until 1-2 addresses remain.
After several cycles of “changed in the game - clarified in the editor” the list of found addresses will be reduced to a minimum. Often there is only one line left. Double clicking on a value allows you to change it to any other value. If after the change the number in the game is not updated immediately, try to perform any action in the game (exit to the menu and return) so that the interface is redrawn.
☑️ Checklist before modification
Working with unknown and encrypted values
Game developers do not always store values in clear text. Often simple encryption is used, for example, a health value of 100 is stored in memory as 105 or 199. In such cases, directly searching for the exact value will not yield results. For this purpose, editors have a function Unknown initial value (Unknown initial value).
The algorithm for working with unknown values is based on tracking changes. You start a search using the "Unknown" type, then change a parameter in the game (take damage or be healed). After that, in the editor, select a filter: “Increased”, “Decreased” (Fell) or “Changed”. By repeating this operation several times, you will cut off millions of cells that did not change along with your parameter.
Another obstacle may be double values. The game can store a number in two cells at the same time: one as is, and the other as its inverse value (for example, 100 and -100, or 100 and 4294967196 for a 32-bit system). This is done to check the integrity of the data. If you change only one cell, the game will detect a discrepancy and reset the value or crash. Therefore, when searching, group operations are often used or pairs of values are searched.
| Search type | When to use | Complexity | Efficiency |
|---|---|---|---|
| Exact Value | The number is visible on the screen and is not encrypted | Low | High |
| Unknown | The value is hidden or encrypted | High | Medium |
| Range | The approximate range of numbers is known | Medium | Low |
| Fuzzy | For floating point numbers | High | Average |
⚠️ Attention: Game interfaces and protection methods are constantly being updated. What worked in version 1.0 may change in patch 1.1. Always check the relevance of scripts and methods on specialized forums.
Automating processes through scripts
Manually changing values every time you start the game is a tedious process. For automation, memory editors such as GameGuardian provide support for scripts in the Lualanguage. A script is a ready-made code that itself finds the necessary addresses, applies changes and can perform additional functions, for example, turning on “immortality” only during battle.
Scripts allow you to implement complex logical chains. For example, the script can monitor the number of cartridges and, when it becomes less than 5, automatically add another 30. This eliminates the need to constantly switch between the game and the editor. Ready-made scripts can be found in modder communities, but launching them requires caution, since the code may contain malicious Payload.
How to check the security of a script?
Open the script file in any text editor before launching. Look for suspicious commands such as downloadFile, writeFile, or launching external URLs. If the script simply operates on memory addresses (read, write, searchFloat), it is most likely safe.
Loading and running scripts often requires an internet connection within the memory editor itself. In the GameGuardian settings there is a "Lua" section where you can paste a link to the file .lua. After downloading, the script will appear in the selection menu and will be ready to be activated along with the game process.
Risks, anti-cheats and account security
Using modified clients or interfering with the game’s memory violates the user agreement of most projects. In offline games, the maximum risk is the unstable operation of the application. However, in online projects the situation is more serious. Anticheats (protection mechanisms) constantly monitor the integrity of memory and signatures of running processes.
There is a concept of “hardware ban” (HWID ban), when not just an account is blocked, but the unique identifiers of the device itself. This makes it impossible to create new accounts from this smartphone. In addition, modified versions of games (mod-apks) downloaded from third-party resources may contain Trojans that steal passwords from Google accounts or banking applications.
To minimize risks, experienced users use separate devices to test mods, without linking their main accounts to them. It is also recommended to use tools to hide root access, such as Magisk Hide or Zygisk, which mask the fact of interference in the system from scanning applications.
Use the "Save List" function in the memory editor. If the game is updated and the addresses are lost, you can quickly check which of the old addresses are still valid without starting the search again.
⚠️ Attention: In online games with a PvP component, the use of cheats spoils other people and can lead to eternal blocking. Use the knowledge responsibly only in modes or on private servers.
Frequently asked questions (FAQ)
Is it possible to change the value in an online game without root access?
Technically, this is only possible through emulators on a PC, where root access is built-in, or using virtual spaces on Android (VMOS). On a regular non-rooted device, the editor application will not have access to the memory of another process due to Android security restrictions (Sandbox).
Why does the value immediately go back after changing?
This means that you changed the local copy, but the server or the main game thread continues to overwrite it with the current value. Either you found the display address (UI), and not the storage address of the variable. Try looking for a related value (for example, health + max health) or using the Freeze function.
Is it safe to use GameGuardian on your main Google account?
No, it’s not safe. There is a risk that your account will be blocked by the game developers or Google Play itself for violating the terms of use. Always create test accounts to experiment with memory and cheats.
What to do if the search returns thousands of results?
Use more specific filters. If you are looking for health, which is rarely greater than 1000, limit your search range (0 to 1000). If the value is fractional, change the type from DWord to Float. Changing the search type to "Changed value" after an action in the game also helps.
Do you need the Internet for the memory editor to work?
For the memory changing function itself, the Internet is not needed, everything happens locally in RAM. However, the Internet may be required to download scripts, update the signature database, or if you are using cloud settings profiles.
Key takeaway: Changing values in a game is a powerful tool for learning how software works, but it requires caution, an understanding of memory structure, and awareness of the risks of blocking in an online environment.
