Signed Apk should work because I have tested it on my device having android OS 13..if it's not working may be the game is not compatible for your device.. first check whether the playstore version is compatible for your device.Can't install on my phone android 9.. already try all file
Can u check bro @Usogui ☆
If PS ver is compatible then, the only solution (which I know) is you have to install any virtual/VM app like VMOS, VPhoneGaga, F1VM etc or use emulator if you can play on PC.
