In split screen, 2-4 players can race against each other on a single device. This feature works best on a TV-connected device like a console or Android TV.
To play split screen, you'll need to have 2-4 game controllers connected to your device. Once you have the controllers connected, click the "Split Screen" button, and follow the instructions!
For mobile platforms like Android TV and Fire TV, you can find information about different types of controllers and how to set them up on this web page. You also will need to purchase the "Premium" version of the game.
(Please note, BBR does not support Chromecast. You need to connect your device with an HDMI cable, or play on a directly connected device like Android TV.)
