Is your child playing Kodable without headphones on? You can mute the game music while keeping the instructions and sound effects on. To mute the music from Fuzztopia, tap the green settings gear icon, then tap the orange "Music" button.
If your learner is in the middle of playing a game, tapping the yellow pause button in the corner will bring up the "Music On/Off" option, as well.
These options look and function the same way across all devices, including the web version game.kodable.com.
