Tennis Racketeering is a game which features the use of the Android Wear device or another Bluetooth phone as a racket. Like any motion game from Wii of Nintendo.
Phone sensors cover strength and direction of a hit. You can play it solo, or multiplayer. If you are afraid of breaking your phone and don’t have a watch, you still can play by tapping the screen =)
Use your Chromecast to maximize the fun.
