The game only runs in landscape mode and it will auto-rotate to this mode at startup. If you have locked your device's rotation, please unlock it.
- The device could have its rotation locked and hence be overriding the landscape orientation
- Please check the device’s auto-rotate settings to make sure auto-rotate is ON
- Then start the game with the device in the landscape orientation
To check auto-rotation settings, go into the Settings app, select Accessibility and then make sure Auto-Rotate Screen is checked.
