Can anybody help with what might be a stupid question? I have downloaded Fishing Paradise 3D onto my HTC One M7 and run it no problem with wifi connected. However, it's offered on Google Play as an 'offline game', so I'd like to play it offline if I need to. With wifi off, the game checks for a connection, refuses to load and I only get the option to quit. If I start the game with wifi on, I thought I might be able to the switch off wifi, but if I press the Back button nothing happens? If I press the Home button to get to wifi settings, the game is quit automatically. How do I play this, or any other 'offline game', offline?
