• Android 7.0 or newer, on a phone or a tablet.
  • Landscape. The game turns itself sideways, on tablets and foldables too.
  • Space for a large download. Every line in the game is spoken and every scene is painted, so it is much bigger than most games of its kind. Downloading it over Wi-Fi is a good idea.
  • No internet connection is needed to play. The game only goes online to ask Google Play whether the full game has been bought, and it remembers the answer, so a bought game keeps working offline.

Everything that is spoken also appears on screen as text, so you can play with the sound off. The Settings panel has separate volume sliders for Music, Narration and Effects; see Controls.
