Mobile gaming has long ceased to be just entertainment for short sessions on the subway; today they are complex ecosystems with real economies and fierce competition. However, the desire to gain an advantage over other players or simply complete a difficult level without unnecessary grinding (monotonous leveling) pushes users to search for tools to modify the gameplay. One of the most powerful and accessible tools for these purposes is Cheat Engineported to the Android platform.
This tool, originally created for the PC, allows you to work with the RAM of running applications in real time. With its help, you can find and change the values of variables responsible for health, currency, ammunition or other game parameters. The process is not a magic spell, but is a technical procedure for analyzing the state of RAM your device.
It is important to understand that interfering with the operation of the app code carries certain risks. Incorrectly changing bytes can lead to application crashes, corrupted saves, or account blocking by game developers. This article provides only technical information about the principles of working with memory and debugging tools.
⚠️ Attention: Using third-party software to change data in online multiplayer games often violates the user agreement. This may lead to permanent blocking of your account by the project administration.
The principle of operation of the memory scanner on mobile devices
The work is based on the mechanism of scanning the address space of the process. When the game starts, it reserves a certain amount of RAM for storing variables. For example, the amount of gold can be stored as an Integer at a specific address in memory. The user's task is to find this address and change the value. Cheat Engine lies the mechanism for scanning the process address space. When the game starts, it reserves a certain amount of RAM for storing variables. For example, the amount of gold can be stored as an Integer at a specific address in memory. The user's task is to find this address and change the value.
On the architecture Android this process is complicated by the security system and application isolation (Sandbox). Each application runs in its own container and does not have direct access to the memory of other processes without special privileges. That is why for the full operation of the memory scanner, root access (superuser rights) are required.
Without root access, the capabilities of the tool are severely limited: you will be able to analyze only those processes that belong to your user and are not protected by the system, but changing them will be extremely difficult or impossible. With root access Cheat Engine gets access to system calls ptracethat allow you to attach to other processes and modify their memory.
The search algorithm is usually based on the filtering method. You don't know the exact address of the variable, but you know its current value. The scanner makes a list of all addresses where this number is stored. Then you change the value in the game (spend gold, take damage) and re-search for a new value, filtering out unnecessary addresses.
Preparing the environment: Root and installing software
The first and most critical step is to obtain superuser rights on your device. Without this step, further actions are pointless. The rooting procedure is unique for each smartphone model and version Android, but the most universal solution today is to use a manager Magisk.
After obtaining root access, you need to install the memory scanner itself. The official version Cheat Engine for Android is available as an APK file. When first launched, the application will ask for permission to use superuser rights - it must be provided, otherwise scanning other processes will be impossible.
☑️ Preparing the device for hacking
It is worth considering that many modern games use root access detection. If the game refuses to run with Magisk, you will need to use the Magisk Hide or Zygisk function to hide the fact of system modification from a specific application. This adds an additional layer of complexity, but is necessary for working with protected projects.
⚠️ Attention: Obtaining root access will void the warranty on the device in most service centers. This also increases the system's vulnerability to malware.
Searching and modifying numerical values
The main use case is searching for mutable resources, such as currency or experience points. Let's say you have 1500 coins. In the scanner interface, you enter the value 1500 in the field Value and select the scan type Exact Value (Exact value). The data type is most often 4 Bytes (integer number), but it can also be Float (floating point number) if we are talking about health with fractional values.
Press the button First Scan. The scanner will analyze the memory and produce a list of thousands of addresses where the number 1500 occurs. Now return to the game and change the number of coins: spend 100 or earn 50. Let's say it becomes 1400.
Enter a new value 1400 in the scanner field and press Next Scan. The list of addresses will be drastically reduced. Repeat the procedure until 1-3 addresses remain. A change in the value in the found address will be instantly reflected in the game.
If the value in the game is displayed as 1500, but you cannot find it in memory, try looking not for the number itself, but for its double value or a value with an offset. Some games use simple obfuscation algorithms.
Search for unknown values is available for advanced users. If the game does not show the exact number of health (only a bar), you can select the scan type Unknown initial value, then after receiving damage select Decreased value. This allows you to find variables even without knowing their exact numeric equivalents.
Working with data types and encodings
The wrong choice of data type is the most common cause of hacking failures. Games store information in different ways. Integers (number of items) usually occupy 4 bytes (DWORD). But money in complex economic simulations can be stored as 8-byte numbers (QWORD) or floating point numbers (Float/Double) to support fractional percentages or large amounts.
Text strings, such as a character's name or item name, are encoded in String or Unicode. Trying to change a string using a number search is doomed to failure. To work with text, Cheat Engine provides a separate scanning mode Stringthat searches for byte sequences corresponding to ASCII or UTF-16 table characters.
| Data type | Description | Usage example | Size |
|---|---|---|---|
| 4 Bytes | Integer | Gold, ammo, level | 32 bits |
| Float | Floating point number | Health (HP), X/Y coordinates | 32 bits |
| Double | Double precision number | Precise scientific calculations, large amounts | 64 bits |
| String | Text line | Nickname, item name | Variable |
| Array of byte | Byte array | Search for unique code signatures | Any |
There is also a type Encrypted Valueused in games with the simplest protection. The value in memory is not stored in its pure form, but with an encryption key applied (for example, XOR). Cheat Engine can automatically select a key if the value changes in a predictable way, but this requires enabling a special option in the scan settings.
What is XOR encryption in games?
This is the simplest method of protection, where the real value (A) is mixed with the key (B) bit by bit. The result A^B is stored in memory. When reading, the game does the operation again and gets A. The scanner can find such values if you know how they change, even without knowing the key.
Advanced techniques: Pointers and freezing values
Simple address modification has one critical drawback: dynamic memory allocation. When you restart the game or even when loading a new location, the address of the variable will change. You will have to do a long search again. The solution to this problem is to work with Pointers (pointers).
A pointer is an address that stores another address. Games use chains of pointers to access player data, which is always located in static memory locations. By finding a chain of pointers (Pointer Scan), you gain access to the variable regardless of where it moved in RAM the next time it is run.
Function Freeze (Freeze) allows you to fix the value at the address. If you freeze your health at 100, then no matter what damage you take in the game, the script will instantly return the value back to 100. This creates the effect of immortality. However, in online games this is often detected by anti-cheat due to the abnormal frequency of sending packets with the same data.
To implement complex scripts, you can use the built-in assembly language or Lua. This allows you to write automatic scripts that perform actions when certain conditions occur, for example, automatically picking up objects or shooting when an enemy appears in sight (aimbot).
⚠️ Attention: The freezing function creates a high load on the processor, since the script is executed every screen refresh cycle. This can cause overheating of the device and throttling.
Compatibility issues and anti-cheats
Modern mobile games, especially popular shooters and strategies, use powerful server-side anti-cheats, such as BattlEye or publishers' own developments. They check the integrity of the game files and the presence of extraneous processes in memory. Detection Cheat Engine in the list of running applications can lead to an instant kick from the match.
Even if you managed to change the value on the client (on your phone), the server may not accept this data. In Server-Side Authority architectures, all important calculations happen on the server. You may see that you have 9999 rounds of ammunition, but the server knows that you have 30 and simply won’t let you shoot an extra time. This is called Desync.
In online games with server verification (MMORPG, shooters), hacking through the Cheat Engine is practically useless for gaining a real advantage and only leads to a ban. This tool is effective mainly in offline single player projects.
Some developers implement Anti-Debugging protection. The application checks to see if a debugger is attached to its process. If the check is positive, the game closes. Bypassing such protection requires deep knowledge of reverse engineering and modification of the application's own binary code (APK), which goes beyond simply using a memory scanner.
Security and Ethical Considerations
Using memory modification tools requires responsibility. Downloading ready-made cheat tables (.CT files) from unverified sources carries the risk of infecting your device with viruses or Trojans. The script in the table may contain malicious code that will steal your passwords or bank card data.
Always check the reputation of the table author and scan files with an antivirus before importing into Cheat Engine. Remember that you are giving the executing code full root access on your device. An error in the script can lead to a “bootloot” (infinite reboot) of the system if critical system processes are affected.
Respect the work of developers and other players. The use of cheats in multiplayer spoils the experience of the game for honest users and undermines the economics of the project. It is recommended to use the acquired knowledge exclusively for training, testing your own applications or completing single games for entertainment purposes.
Is it possible to get a ban for using it in an offline game?
In purely offline games (without an Internet connection), there is no risk of a ban, since there is no server to record violations. However, if the game requires a constant connection to verify the license (DRM), a hacking attempt may be considered a violation of the license.
Is Root required for Cheat Engine to work on Android?
Yes, to scan and change the memory of other applications (games), root access is required. Without them, you will only be able to analyze the processes of the Cheat Engine itself or system processes with very limited rights, which makes hacking games impossible.
Why does it immediately go back after changing a value in the game?
This means that you did not change the main address of the variable, but the temporary mapping, or the value is protected and is constantly overwritten by the game loop. Try using the "Freeze" function or finding a Pointer to the true data storage address.
Is it safe to use Cheat Engine in online games?
No, it is extremely unsafe. Anti-cheats for online projects easily detect the presence of a memory scanner process or abnormal variable values. The result is almost guaranteed to be an account ban (Ban) without the possibility of recovery.
What to do if the game crashes when trying to scan?
The game probably has debugging protection or you selected the wrong data type, which led to a memory conflict. Try hiding root access through Magisk Hide for this particular application or use softer scanning methods.
Is it possible to hack a game if the values are encrypted?
Yes, but it is more difficult. Cheat Engine supports searching for Encrypted Values if the encryption algorithm is simple (for example, XOR with a constant). Complex encryption will require disassembling the game code and finding a decryption function.
