Explore 240 puzzles across 16 chapters. Trace a single line through folded spaces, discover new angles, and return for a daily challenge.
One line. A different way to see.
SIGHTLINE is a minimalist perspective puzzle game where your path travels across floors, walls, and raised planes. Connect the start to the finish in one continuous line, reach the required nodes, and find your way through folded space.
Explore 240 main puzzles across 16 chapters. Begin with simple connections, then take on increasingly intricate routes with branching paths, one way tracks, and limited ink. Later puzzles ask you to change your viewpoint and think across layers.
Look closely before you draw. A route that seems out of reach from one angle may make sense from another. Follow connections between planes and discover how each part of the space fits together.
Play at your own pace. Undo a move, restart a puzzle, or return to an unfinished attempt. When you need a little help, three levels of hints let you choose how much of the solution to reveal.
Return for a daily challenge and revisit recent challenges from the archive. Keep your completed runs in your collection, watch your route again, and share a short highlight video or a challenge card that keeps the solution hidden.
Enjoy clean geometry, restrained color, sound, and haptic feedback. Adjust sound and haptics, enable high contrast, or reduce motion to make the experience more comfortable.
Your progress is saved on your device. Play the main puzzles offline, with no login required and no in app purchases or subscriptions.
Find the connection. Change your perspective.
