Well, it comes down to a difference in processor architecture. There is a big difference between ARM and x86/64 processors. ARM is mostly used in mobile devices like phones/tablets and x86/64 is typically laptops/desktops. If a game (or program) is going to be released on a certain platform, then it needs to be specifically created using that platform's architecture. That's why your laptop doesn't run Android/iOS apps and why Windows/Mac programs and games don't work for Android/iOS. A developer has to make their game for that specific computing architecture. Think of it like trying to insert a bluray into a dvd player, sure they are both movie formats, but the format themselves are targeted for a specific device (in this case dvd players vs bluray players).
