Sounds And Settings
Success sounds, quiet games, and per-game settings.
Sounds Are Off Until You Want Them
Success sounds in games start muted by default, per game. Turn them on from the settings gear on any game screen. Wrong answers never play sounds, on purpose.
Each Game Remembers Its Own Settings
Sound and difficulty choices are saved per game on the device, so one learner's loud game does not change another's quiet one.
