While I realize that there are games on the market that are multi-platformed, but those games were designed that way.  Castle Clash however was not it was designed as stand alones.  In regards to playing your Android account, the only means would be with an Android device or an Android emulator compatible with your device.  Sorry I don't know of any to refer to you.  However you also have the option of playing on a PC, again with the assistance of an Android emulator.
