The lighthouse beam sweeps the maze all night. Roll your marble from shadow to shadow and reach the green harbor light without being seen.

Shadeslip is a quiet, tense tilt maze. Every wall casts a real shadow, the beam sweeps round on a steady rhythm, and the only safe place is the dark. Stay in the light too long and you are spotted.

How it plays
• Tilt your phone to roll the marble, or drag anywhere on the screen to tilt the board.
• Walls cast shadows. Wait behind one until the beam has passed, then make your dash.
• Each level hides three pieces of sea glass. Collect them all for a perfect escape.
• The mazes grow, the beam turns faster and a second beam joins in as you go deeper.
• Clear a level to unlock the next. Play any cleared level again to beat your best time.

Made to be picked up and put down
• Short levels, easy to pick up and put down.
• Your progress and best times are saved on your phone. No account and no sign-in.
• Works offline.
• Choose tilt or touch controls, set the tilt sensitivity, switch off vibration or sound, and turn on Reduce motion if moving scenery bothers you.
• Menus work with large text sizes and with screen readers. (The maze itself is a picture: it cannot be played by screen reader.)
• Graphics adapt to your phone, with a battery saver that draws 30 frames a second.
• Plays on phones and tablets.

About ads
The game's only ad is an optional video. If the beam catches you, you can choose to watch a short video to carry on from where you were, or simply try the level again. There are no ads between levels. Where the law asks for it, the game first shows Google's privacy choices, which you can change later in Settings.
