Why there are two builds
The app ships two APK builds because Android phones come in two processor flavors. The 64-bit build is made for modern phones and the 32-bit build keeps the game working on older devices. Both contain the exact same game: same 2019 content, same unlocked heroes, same features. The only difference is which phones can run them.
How to check your phone
The fastest check: if your phone was made in the last several years and runs Android 8 or newer, it is almost certainly 64-bit. To be sure, open Settings, go to About Phone, and look at the processor or Android version info, or check the kernel architecture with a free device info app. Phones with 2 GB of RAM or less and very old Android versions are the main candidates for the 32-bit build.
The 64-bit build
This is the default choice for nearly everyone. It matches the architecture of modern phones, which means smoother performance and fewer surprises. If you are unsure, start here. You can find both builds on the app download page.
The 32-bit build
The 32-bit build exists for old budget phones that cannot run 64-bit apps. If the 64-bit APK throws a Parse Error on install, that is your signal to switch to 32-bit. Gameplay is identical; you just get compatibility with legacy hardware.
Can you switch builds later?
Yes, but you must uninstall the old build first, since the two have different signatures and Android will not install one over the other. Your local progress will not carry over, so only switch if you need to. New players should follow the installation guide after picking their build.
