Overview
A shape made of dots and edges, one finger, and a single unbroken line to draw it all. The rule is the classic one-stroke challenge: press on a dot, drag along the edges, and cover every segment without ever retracing your path. Trace the whole figure before the 60-second countdown ends and the level is yours. It is the headline mode of a small puzzle collection - a hall of minigames with more brain-teasers behind its doors - but the fifty-stage one-stroke ladder is where the journey starts.

Objective and input
How to Play
Pick a starting dot and press down, then drag a continuous stroke along the shape's edges. Each edge you trace stays marked, and the game refuses to let you retrace a segment, so the route has to cover everything in one go. Finish every edge before the 60-second timer runs out to clear the level and unlock the next of fifty. When the clock wins, a fail panel offers a retry. Beyond one-stroke, the hall hosts other minigame modes - including a maze variant on a longer 80-second clock - that unlock as you progress.
Mobile Controls
Touch a dot and drag one continuous stroke along the edges without lifting your finger.
Retracing a segment is not allowed; plan the full route before you start.
Watch the countdown: each level gives you 60 seconds to finish the figure.
What stands out
Features
True one-stroke puzzles
Every figure is an Euler-path riddle: cover all edges in one unbroken line, with retracing blocked by the rules themselves.
A fifty-stage ladder
The one-stroke mode runs fifty levels, from a simple triangle to dense multi-cornered figures.
A real clock
Each level runs on a 60-second countdown, turning a calm tracing exercise into a focused sprint.
A hall of minigames
One-stroke is the centerpiece of a broader collection; the hall holds further modes, including an 80-second maze variant.

Gameplay Tips
- 1
Read the whole figure before touching a dot; a five-second plan beats a failed stroke.
- 2
Start from an unusual corner - figures with odd junctions usually only work from one end.
- 3
Drag steadily rather than fast; the stroke only counts edges it truly touches.
Common questions
Frequently Asked Questions
Is there a time limit?
Yes. Each one-stroke level gives you 60 seconds; the maze mode runs on 80 seconds. Running out brings up a fail panel with a retry.
What happens if I try to retrace a line?
The game blocks it. Each edge can only be traced once, which is the core of the one-stroke rule.
How many levels are there?
The one-stroke mode offers fifty stages, and the collection hall holds additional minigame modes beyond it.
Does it work with a mouse on desktop?
Yes. Pressing and dragging with the mouse traces the same strokes as a finger on touch screens.
