Air Cube · How to play

A few steps before you start

• Put your hand behind the phone

  Point the phone at the space the cube lives in and gesture in front of the lens. Only your two fingertips show on screen — never the camera feed.

• Pinch with thumb + index

  Pinch to grab a face, hold still a moment to lock it, then turn your two fingers to twist it.

• Turn your fingers to twist

  Once locked, keep pinching and rotate your two fingers to twist that face; open your fingers to unlock and grab another.
