Our take on One Line

Rather than building around timed rounds, scores, or competitive targets, this puzzle centers on a single path across each board. Its structure is a sequence of 50 levels, with new mechanics introduced as the puzzles become harder.

What is One Line?

One Line is a puzzle game built around drawing a single path that fills the whole board.

Use the mouse or arrow keys to draw, then undo moves or erase part of the path with a right-click. New mechanics appear as play progresses, adding difficulty across 50 levels with progressive challenge. There is no tutorial, score, or timer: play starts directly, and puzzles can be solved at the player’s pace. The game focuses on finding a route through each board, with mistakes handled by revising or removing the drawn line.

How One Line plays

02Progressive levels

03Untimed play
