All guides →How to Install an XAPK
- An XAPK is a ZIP archive with the APK and extra game data.
- Rename the file from .xapk to .zip and extract it.
- Install the APK file inside the extracted folder.
- Copy any Android/obb folder to the same place on your storage.
How to Install OBB Data
- Install the game APK first, but do not open it yet.
- Open a file manager and go to Android/obb on internal storage.
- Copy the folder named after the game package (for example com.example.game).
- Open the game; it will find its data automatically.
How to Verify the File
- Copy the SHA-256 checksum shown next to the download.
- Calculate the checksum of your file with a hash app or certutil on Windows.
- If both values match, the file is exactly the original.
- Updates install over the old version only if the signature is the same.
