Colorblind mode
The train colors come from one palette chosen to stay distinct for most kinds of color blindness. Colorblind mode, in Settings, goes further: it adds a shape badge to every train and station, so you can match them by shape.
Reduced motion and sound
Reduced motion turns off shake, particles and confetti. The lit route stays: it is information, not decoration.
Sound effects, Music and Haptics switch on and off one by one.
Themes and languages
Theme offers three colors for the board. The app speaks 36 languages, Arabic and Hebrew included; it follows your phone, and Language lets you pick another. See Settings.
