Hiya DigitalDiamal!
With most APKs, you can simply rename the .apk file to a .zip file and extract it from there, or use an application like 7-Zip to directly unpack the APK. Also, some game data is found in OBB (.obb) files, which are usually found either on your device in the proper "obb" folder, or within XAPK (an app package containing both an .obb and an .apk) files. APK, XAPK, and OBB files can all be unpacked in the same fashion as referenced above.
Hope this helps, cheers!
