I don’t have any sound when I play the app.
Our apps have the ability to toggle sound on and off, so start by checking the app itself. If sound is enabled but you still cannot hear anything, check your device’s volume switch, which is usually located on the top or side of your device. iOS users can also swipe upwards from the home screen, to bring up their settings and enable or disable sound from there.
