Use the Siri Remote for game play on Apple TV
The Siri Remote included with Apple TV 4K and Apple TV HD (Late 2017) has an accelerometer, gyroscope, and built-in compass for playing a variety of games. Depending on the game, you can hold and move the remote in three dimensions (pitch, roll, and yaw). Some games respond to movements you make in the air with the remote.
Use the Remote Loop
Attach the Remote Loop (sold separately) and maintain a secure grip on the Siri Remote to prevent injury or accidental damage to the Siri Remote or other property.
To enhance game play, some apps may also work with a third-party Bluetooth® game controller or other accessory, or may require the use of a third-party Bluetooth game controller. Game controller requirements are provided in the app’s product page on the App Store. See Connect Bluetooth devices to Apple TV.
