Actually, it is a little bit of a trap for “young players” (not that I’m actually young).
The iPad has a little button at the top-right-rear, which is “Silence Ringer”. When you switch it, it says “Ringer Silent”.
Well…. unbeknown to me, that button silences the game sound as well as notifications.
I do recall switching that switch “on” when I first got the device, because at that time it was for my parents, and they didn’t want to be getting rings (they weren’t expecting any anyhow).
When I got no sound from my game, I tried other ways of getting sound: I went to YouTube for example. That still works even with the “silence” button on, which is why I thought it was the “game’s fault” that there was no sound.
The other day, I noticed that button again for some reason and a light bulb dinged on….
