You can set the orientation of the screen, as well as Left/Right Controls, from the Settings menu.
When set to Landscape, the screen will be fixed to a landscape orientation during races. When set to Portrait, the screen will be fixed to a portrait orientation (as has been the case since the game's launch) during races. When set to Portrait / Landscape, the game will switch between these two modes during races depending on the current orientation of your device.
When the orientation is set to Portrait / Landscape, or Landscape, you can adjust your Landscape control method with the following options:
・Same as portrait mode
・Left side: Steer / Right side: Use items
・Left side: Use items / Right side: Steer
Notes:
・The tutorial and Practice While Downloading races do not support landscape mode.
・When using an iOS device with Portrait Orientation Lock set to On, the game will be prevented from displaying in landscape (regardless of the in-game Portrait / Landscape setting).
