#SelfieTennis is a sandbox sports game that places players in a unique tennis simulation. The core mechanic involves hitting a ball over the net, which then teleports the player to the opposite side to continue the rally. The game features sophisticated AI "Ball People" who inhabit the court and interact with the player, adding a layer of unpredictable chaos.Beyond traditional tennis, #SelfieTennis provides a variety of sandbox upgrades, including items like lightsabers and bows and arrows, and a ponycorn for traversal. For enhanced physical engagement, the game supports the HTC Racket tracker peripheral, enabling dual-wielding rackets for an intense workout. A GIF recording and Twitter sharing feature, dubbed #SelfieStick, allows players to capture and share their gameplay moments.
