A minimalist path puzzle · On Google Play
One Line
One unbroken line.
Every cell, exactly once.
Calm to play, quick to read and still something to think about. Thousands of levels, each one designed by hand, on a clean board with nothing on it you do not need.
The rules
One unbroken line.
Start on the glowing cell and keep going.
Every cell, exactly once.
The board is solved when the line has passed through every open cell.
Wrong turn? Trace back.
Draw back over your line and it takes the steps back with you.
Go around the walls.
Dark cells are carved out of the board. Later, numbers ask to be reached on their exact step.
Three ways to play
Saga
Numbered levels, one by one, across a map. Every tenth level leaves a few words to keep.
Zen
No clock, no pressure. Honeycomb boards and nothing else.
Endless
Beat the clock and keep the streak going.
Your line
Comet, neon, ink, stars
The line can wear a comet's tail, a neon tube, a stroke of ink or a scatter of stars, and the board takes its colours from the accent you pick.
Made to be comfortable
