One-stroke puzzle game

Trace it in one line.
Lift too early, start over.

Every level is a tangle of glowing lines. Your job: trace all of them without lifting your finger — no matter how tangled it looks, it's always solvable.

How it works

One rule. Endless variations.

No tutorials to sit through. The whole game is one rule, and every level is a new way to test it.

01

Start on the glowing dot

Every level has one or two valid starting points. Find one, put your finger down.

02

Trace every line, once

Drag through the whole tangle without lifting your finger. Cross every line exactly once.

03

Lift early, start over

No hints, no available-path highlighting. Plan the route in your head before you commit.

Every 10th level

Then a boss levels hits.

Dense hub intersections where five or six lines meet at once. Pick the wrong one and you strand yourself with no way out — always solvable, never easy.

levels 1–9, then a boss. every time.
"Every corner is a decision."
"Save the lonely edge for last."
"The busiest dot is the trap."

Every level, scored
