Play One Line Online
One Line is a one line drawing puzzle game played with wooden pegs and braided ropes. Start at a marked peg and follow one continuous route through every rope exactly once. You may revisit a peg, but each connecting rope can be used only once.
How to play One Line online
- Choose a green-ringed starting peg.
- Follow a rope to its next peg, continuing from the last peg you reached.
- Trace every rope once to unlock the next challenge.
Controls
Tap successive connected pegs or drag through them. You may lift your finger between moves; the route still continues from the last peg. Previous and Next select a peg, and Choose peg visits it. Undo stroke reverses the last tap or drag. A cancelled or off-board stroke restores the earlier route.
A tip before you start
Before leaving a branch, check whether the remaining ropes can still be reached. If a move strands a loop elsewhere, undo that stroke and take the loop before continuing.
A one line puzzle game with growing branches
The twenty original graphs increase from four edges to twenty-three. Branching pegs increase in stages, and every starting graph has a verified complete route. The hint allowance decreases at every level, from twenty to one.
Hints check the route that remains
Hint takes one step along a finishing route when one still exists from your current peg. If an earlier choice has stranded the remaining ropes, it explains that you need to undo. It does not silently clear your earlier path.
